cynodon dactylon life cycle

Origin. Pl. ... C4 - C4 photosynthesis that makes a four-carbon sugar during the Calvin cycle instead of two three-carbon sugars as in C3 plants. [21][24] Care must be taken to remove all aerial growth repeatedly throughout the growing season when clipping and mowing are used as a control measure. Arizona Flora. Box 1662, Weldon, CA 93283; (619) 378-2531. Rb phosphorylation and mRNA levels of cyclin E were significantly reduced. The rhizome system is superficial as well as deep, which may account for the ability of this species to infest both arable and waste lands in a variety of conditions. When nitrogen is limiting, and the growth conditions unfavorable, fructosans accumulate in the rhizomes. Several techniques are helpful in controlling Bermuda grass. Fluorescence-activated cell sorting (FACS) data revealed that it also induced apoptotic cell death. [10][4] Large amounts of Bermuda grass, including the giant-type, grow along the edge of Roosevelt dam in Arizona, where it survives submergence under water for part of the year and provides food for cattle during the dry periods. 1969. Belsky, A. J. [9] [30], Single-bud rhizomes were planted and monitored throughout several growing seasons. The inhibition is proportional to the concentration of plant material. The following is a description of the general life-cycle of Cynodon dactylon. Life cycle Vivacious . Shade tolerance studies on Bermudagrass and other turfgrasses. Cynodon dactylon and Medicago sativa are two important species using in ecological restoration. However, careful monitoring may show this to not be the case. The temperature, precipitation, humidity and elevation will determine the optimal control technique. Cooperative Extension, which staffs local offices in all 100 counties and with the Eastern Band of Cherokee Indians. [3] A large amount of available nitrogen is required for maximal above-ground growth; this element is often the limiting factor for Cynodon dactylon. [1], Cynodon dactylon grows throughout the warmer regions of both hemispheres. Elongation of the internodes on the shoot is followed by the development of up to twenty buds per node. Effect of temperature, daylength, and solar radiation on production of coastal Bermudagrass. The University Press of Hawaii, Honolulu, Hawaii. In fact, the red Gramigna is perfectly suited for cultivation even in areas with particularly dry sandy soil. Cynodon dactylon Bermudagrass. [29] The open growth pattern of Bermuda grass's stolons provides for greater land coverage than seen with species which lack stolons, such as Sorghum halepense; the average monthly area increase in the warm season for Cynodon dactylon and Sorghum halepense is 1.6 m2 and 1.3 m2, respectively. Abstract: Seed germination and seedling establishment is a critical stage in the life cycle. Weinmann, H. 1961. Ayurveda Health Benefits and Uses of Durva Grass or Cynodon Dactylon. A substantial amount of the world's salable seeds of this "giant" Bermuda grass is grown near Yuma, Arizona. Cynodon dactylon . Crop Sci. 1987. 1969. Cynodon dactylon can be an invasive and competitive weed. Growth habit Grows up to 2 ft. tall; goes dormant in winter and turns brown. Growth is greater on heavy clay soils than on light sandy soils in dry regions; this may be due to the greater water holding capacity of the clay. The burn resulted in a drastic reduction in Bermuda grass from 14.7 g/m2 to 0.2 g/m2 as compared to the increase in Johnson grass from 0.2 g/m2 to 27.4 g/m2. Studies to determine the optimal native species to be used and re-vegetation schedule to be followed must be conducted. Growth begins at temperatures above 15 °C (59 °F) with optimum growth between 24 and 37 °C (75 and 99 °F); in winter, the grass becomes dormant and turns brown. 1846. Hardison, J. In some turf settings, it is considered very invasive and difficult to control weed. Very poor shade tolerance. Accepted name. Since Bermuda grass is low growing and not always readily apparent, some type of marking system should be employed in order to expedite the yearly measurements. 159pp. Johnsongrass- two decades of progress in control. California Press, Berkeley. Digitaria ciliaris Echinochloa colona. Jameson, D. 1963. NVS code Help. Warm-season perennial with stolons and rhizomes. Refer to TurfFiles for cultural and chemical management. Temperate and Subtropical Old World to Australia, Full sun (6 or more hours of direct sunlight a day). Some winter kill is to be expected when winter temperatures dip below 10 degrees F. Needs regular dethatching. Removal of the aerial portion of perennial plants may slow the growth by limiting the accumulation of carbohydrates. However, with the exception of extremely dry conditions or long periods of fire suppression, both of which result in hot fires that may damage the rhizomes, most rhizomatous grasses, such as Cynodon dactylon tend to benefit from fire. Full publication details for this name can be found in IPNI: urn:lsid:ipni.org:names:126098-3. In the spring when the temperature begins to increase new stolons elongate and aerial shoots sprout (Horowitz 1972a). Bermuda grass is used in warm regions around the world as a lawn and pasture grass and for golf greens. [34] However most burning experiments conducted in swampy areas result in the increase in abundance of Bermuda grass. Abstract: Seed germination and seedling establishment is a critical stage in the life cycle. Life Span : Perennial: Growth Form : 1.5-2.0 feet tall, decumbent, presents stolons and rhizomes, (sod type growth). [5][6][3] Although widespread, this species "thrives only under extreme disturbance and does not invade natural grasslands or forest vegetation". [12], An increase in nitrogen fertilizer from 0 to 900 pounds per acre results in an increase in height (2.5 inches to 6.5 inches), percent protein, yield (1.6 tons to 11.0 tons of hay), stem length (6.0 to 17.0 inches), internode length and node number, and a decrease in leaf percentage and seed head frequency (5% to 2%). recommend the fall spraying of herbicides for maximum effectiveness. In September while the plants where in full bloom, one week before spraying 2% glyphosate from a boom-sprayer, the field was irrigate to encourage growth. As a desirable turfgrass, bermudagrass is typically maintained at less than 1 inch mowing height. Cynodon dactylon (L.) Pers. Nitrogen fertilizers are routinely used in order to increase the forage and turf value of Bermuda grass. Couch grass can be used as a cover crop in orchards and used for erosion control purposes. An alternative to desiccation is freezing. Bermudagrass is a fast growing warm season perennial grass that spreads rapidly by seed, underground rhizomes and surface stolons (runners). [8] Average daily temperatures above 24° C are necessary for substantial growth and temperatures of 38° C result in maximum growth rates. (C. dactylon) is a perennial herb, who is one of the dominant species in the riparian zone. [4] In areas of low rainfall it commonly grows along irrigation ditches and streambeds. Many years of spot control may be required until all remaining Bermuda grass is removed or until the ground is covered by the native vegetation. Holm, L. G., P. Donald, J. V. Pancho, and J. P. Herberger. Genus Cynodon Species dactylon Variety Cultivar Common names Bermudagrass Family POACEAE Specimen number S14002 Data source Allergy p122;BtrflyCa p205;BtrflyCa p209;BtrflyCa p227 Life cycle Life form Terrestrial Life cycle Various Life span Annual cycle Not applicable Stature Grass Growth form Not applicable Growth habit Decumbent Overall height Overall spread Echinochloa crus-galli ssp. [30] Germination tests will determine the fertility status of the variety in question. [9] Concentric growth, outward from the original rhizome sprout, of the rhizomes corresponds to the circular above-ground growth pattern. 2 pictures total. Changes in sod area can be determined by comparing the area of the annual concentric circle growth size drawn on a contour map, plotted by making a grid with poles spaced 1 m apart and then subtracting the size of the bare areas. Effect of nitrogen fertilization on the carbohydrate content of coastal Bermudagrass (, Prine, G., and G. Burton. Family: Poaceae Life Cycle: Perennial Type: Grass Description: A warm-season species that spreads by aggressive rhizomes and stolons.It is often considered a weed in lawns and landscapes, but improved varieties are widely used for lawns, golf, and athletic turf due to its resiliency and tolerance of low mowing heights and traffic. Weeds of the U.S. and their control. Similar inflorescence to Digitaria species, but the foliage on Cynodon dactylon is more robust and stiff. [16], Carbohydrate levels in Bermuda grass do not generally follow a consistent pattern. Greater than 48 hours of drying over an ammonium chloride solution kills actively growing stolons, whereas greater than 96 hours is required to destroy post-dormant fragments. 355 pp. The characteristic prostrate growth of Bermuda grass lasts for one to several months, early in the season, before flowering culms develop. However, Bermuda grass is sensitive to shade and frost damage, and only invades disturbed land. [13] Increasing the level of nitrogen while maintaining a low light setting results in a further reduction in growth; nitrogen fertilizer increases the retarding effect of low light on shoot, root and rhizome yield, and decreases the amount of reserve carbohydrates while increasing the amount of crude proteins. 1: 85 1805. Cynodon dactylon (L.) Pers. Revegetation of artificial disturbances in grasslands of the Serengeti National Park, Tanzania; colonization of grazed and ungrazed plots. The effects of late winter litter burn on the composition, productivity, and diversity of a 4-year old fallow-field in Georgia. 1988. [10], In addition to competing with native plants for nutrients, Cynodon dactylon presents a direct threat to agricultural crops and possibly to natural vegetation by acting as an alternate host to eleven arthropods, twelve nematodes and numerous viruses.[9][41]. Yellow and purple nutsedges (Cyperus esculentus L. # CYPES and C. rotundus L. # CYPRO) are herbaceous perennial weeds that are among the worst pests known.Holm et al. [3] It grows on soils with a wide range of pH values, however alkaline soils are tolerated more than acidic ones. p.1. 2a. Watch for mites. The following is a description of the general life-cycle of Cynodon dactylon. Life Span : Perennial: Growth Form : 1.5-2.0 feet tall, decumbent, presents stolons and rhizomes, (sod type growth). Removal of the weed in the adjacent land may be required if invasion occurs frequently. ... Life Cycle. Diseases, Insects, and Other Plant Problems: No serious insect or disease problems. 1973. Fire and disease. [18], New stolons are formed at the basal node of shoots which had developed from over-wintering rhizomes. [30] New stolons can grow 75 cm in the first six weeks after sprouting. Ischaemum rugosum Bermuda grass, (Cynodon dactylon), perennial turfgrass of the family Poaceae, native to the Mediterranean region. Plants spread rapidly, and can make 3 feet or more of horizontal growth in a season. In general, if conducted at the correct time, burning will slow down the growth of perennial grasses. Aphid populations in northern India decline in response to heavy winter rainfall and hail. comm., Silberman pers. aridus Harlan & de Wet. Common name: Bermudagrass Latin name: Cynodon dactylon L. Pers. Uninfested sites with bare or unshaded spots surrounded by areas containing Bermuda grass: If the site is undisturbed than most likely Bermuda grass will not invade it. Most of these techniques are not economically or practically feasible in a non-agricultural setting. Thus if land adjacent to invaded areas remains covered by natural vegetation, Bermuda grass will be unable to spread into it. Please mention your ailment or if there are any side effects you are facing. 178 pp. comm.). The extensive stolon and rhizome system provide a means of rapid expansion. Cynodon dactylon's competitiveness is thought to stem from its ability to reduce the level of nutrients to below the necessary amount needed by Acacia smallii; this assumption is based on the increase in Cynodon dactylon's growth in the mixed over the mono-culture treatments, its drastic increase in the fertilized, mixed culture plots, and the growth reduction by 70% to 90% of Acacia smallii in the fertilized mixed plots. Crampton, B. Maximum extension is measured by determining the distance from the center of the sod to the tip of the furthest stolon. [31] However Bermuda grass had a greater inhibitory effect on the competing plants, with a reduction in the yield of Johnson grass, Torpedo grass and Cogon grass by 55%, 38% and 43%. Fire: its effect on grasslands, including swamps-southern, central and eastern Africa. It is a robust plant that survives even the hottest and driest summers. [9][3] The rhizomatous and stoloniferous growth and, depending on the cultivar, the abundance of minuscule seeds, leads to the extensive spreading capabilities of Bermuda grass. 1966. Jeff Weigel, Director of Stewardship, The Nature Conservancy, P.O. In order to prevent the sprouting and establishment of the remaining Bermuda grass rhizomes, native plants and shade material should be installed immediately after the eradication stage. Carbohydrate accumulation of coastal Bermuda grass and Kentucky bluegrass in relation to temperature regimes. Cutting Bermuda grass on hot, dry days has a much greater inhibitory effect than cutting on cool, moist days. Ross, M. 1986. 9:534-537. comm.). Distinguishing characteristics - morphological . Means of propagation - method of reproduction. Long rhizome fragments and dormant stolons require long periods of drying in order to destroy the activity of the buds. Effects of desiccation and submergence on the viability of rhizome fragments of Bermudagrass and Johnson grass and tubers of Nutsedge. Control experiments were employed to test the effects of temperature and humidity on the germination of the two pioneer species. Bermuda grass's notoriety as a tremendous colonizer comes from the spreading ability of both the rhizomes and stolons. 1970. Herbage Abstract 40:233-238. [8] Forty years ago Bermuda grass was considered the leading cause of hay fever in Arizona. The culms take root at the lower nodes. The following people "eyeball" the distribution of the grass: No specific research on Bermuda grass control in natural plant communities is being conducted presently. [19] In the first month a primary shoot and four roots develop from the rhizome. The date of the initial introduction of Bermuda grass into the United States is uncertain, but most likely it occurred in the mid-1800s. This plant requires high light intensity to thrive. [20] The greatest amount of growth occurred at 30° C/24° C (day/night temperatures) whereas the greatest amount of starch in the stem bases and rhizomes of Coastal Bermuda grass occurred in the 13° C/7° C treated-plants. During late spring or early summer adult female ground pearls, which are pink in color, emerge from their pearl cysts, migrate, and then lay up to 100 eggs into a chamber consisting of a wax-like filament. Reproduction. comm., Heathman pers. [15] Half the amount of rhizome and root growth occurred in the 64% shade treated-plants than in the control plants. Common name: Bermudagrass Latin name: Cynodon dactylon L. Pers. [11], Shading drastically affects both above- and below-ground growth. How to convert a Bermudagrass lawn to a gravel or desert landscape. These rhizomes growing deep in the soil provide an over-wintering structure as well as, when they surface, additional above-ground growth.[19]. John Wiley and Sons Ltd., NY. Cynodon species and their value for grazing and hay. Risser, P., E. Birney, H. Blocker, W. May, W. Parton, and J. Wiens. 1950. [3] Bermuda grass can survive long periods of flooding, but little to no growth occurs without adequate soil aeration. Cynodon dactylon, known as Bermuda grass, Dhoob, dūrvā grass, ethana grass, dubo, dog's tooth grass, Bahama grass, devil's grass, couch grass, Indian doab, arugampul, grama, wiregrass and scutch grass, is a grass that is native to most of the eastern hemisphere. comm.). Eliminating aerial growth reduces the carbohydrate availability in the rhizomes. 1971. A reduction in dry weight, leaf area and seed output was most likely due to the large size of the wheat plants which caused shading of the Bermuda grass. 1954. dactylon (from here on referred to by the species name), which have spread to other countries. Various schedules of mowing, grazing, tilling, desiccating and herbicide applications should be studied at different locations. 1977. Weed science in the tropics; principles and practices. Element Stewardship Abstract-, Carey, Jennifer H. 1995. [9] Cynodon dactylon's success as a weed is thought to be a result of the adaptive rhizome characteristics. The depth of penetration is restricted by compaction and aeration. Keck). common bermudagrass Cynodon dactylon . Inconsistent results have been obtained on the effects of burning as a control for Bermuda grass. New rhizomes form only at temperatures greater than 15° C to 20° C; sprouting of rhizome buds is maximal at temperatures between 23° C and 35° C and is inhibited by temperatures below 10° C.[18] No dormancy period is found in rhizomes; sprouting occurs once apical suppression is relieved by fragmentation. In general, total available carbohydrates in the rhizomes increases in the fall, peaking between November and December, decreases in late winter and begins increasing in late spring, reaching a second, but lower, peak in May, and then decreasing in the summer. [18] The total rhizome length of single node rhizome fragments planted in July increases from 36 m per plant in December to 95 m the following July, indicating greater rhizome growth in early summer than in late summer. 2011. Horowitz (1972a)[30] found approximately 70% of the rhizome weight of two and a half year old plants in the upper 20 cm of the soil and no rhizomes below 40 cm. [35] In wet areas, the rhizomes are protected from the heat of the fire. Total available carbohydrates in grasses and legumes. comm., ).[47]. A downward movement of the herbicides most likely coincides with the spring and fall rhizome growth period. 522 pp. polevansii (Stent) J. R. Harlan & de Wet In the list of world’s worst weeds nutsadge (Cyperus rotundus) ranks first and hariali (Cynodon dactylon) second position. Pers. Burton, G., J. Hook, J. Butler, and R. Hellwig. Two major stages, not necessarily temporally separated, are essential for restoring the native flora: eradication of the weed and encouragement of native plants, preferably large, if appropriate. Bermuda Grass (Cynodon Dactylon) The grass known by the scientific name Cynodon dactylon is, by far, the most widely used in both garden lawns and sports fields in some parts of the United States and Southern Europe.Not only is it easy to maintain but it will not be necessary to water it too often. [16] Tall dense trees greatly reduce Bermuda grass growth, and complete canopy cover eventually kills the grass. Greater than 60% of the subterranean weight (600 g/m3) occurs within 1 m of the plant center, 30% in the next meter, with the remaining 10% in the 2 to 3 m range. [30] In two and a half years the average sod area of a single plant is 25 m2, with a maximum growth rate of 2 m2 per month in the summer months. The early establishment of native plants which can shade the Bermuda grass is important to eradication, maintenance and re-vegetation. However understanding the annual carbohydrate cycle is not helpful since rhizome sprouting is not correlated with carbohydrate levels, thus clipping should proceed throughout the entire growing period. [30] Within three and a half months eight stolons from the main shoot and seven stolons from secondary shoots develop, resulting in 570 cm of stolon length. Wilcut, J., B. Truelove, D. Davis, and J. Williams. The eggs hatch several days after being laid. This page was last modified 20:40, 18 June 2014 by. However, this species, which requires high temperatures and high light levels to thrive, grows only in disturbed areas. RESPONSE TO MANIPULATIONS AND ABIOTIC FACTORS: Harlan, J. 1681 pp + supplement. Pers. [30] A random sampling of segments of the infested field may provide sufficient information for large scale problems. Element Stewardship Abstract; Dara Newman, 2001. bermudagrass, common bermudagrass, devilgrass. Friedman, T., and M. Horowitz. var. Cynodon dactylon and Medicago sativa are two important species using in ecological restoration. [26] Actively growing stolons are more susceptible to desiccation than post-dormant stolons. Competitive interactions between, Ramakrishnan, P., and S. Kumar. The characteristic prostrate growth of Bermuda grass lasts for one to several months, early in the season, before flowering culms develop. The weeds with similar morphological characters, life cycle, requirements of soil , water, […] Cynodon dactylon var. A single treatment or combination of clipping, tilling, shading and herbicide application for several years should result in complete eradication of this weed. Journal of Ecology 74:419-437. Journal of Range Management 26(1): 13-18. The greatest regrowth occurred around the irrigated trees. Objectives of knowing the life cycle of weed To determine the correct method of controlling the weeds. comm., Diamond pers. Subterranean growth begins earlier in the spring than aerial growth. [17], The principle means of propagation of Cynodon dactylon is through the rhizomes and stolons. Four feet by four feet shade mats (mulch) were placed around the trees to reduce the sprouting of the remaining rhizomes. Bermuda grass is difficult to control once it has been nurtured and has become established. On 22nd day the animal was induced to develop PCOS. [40], Asexual reproduction, not sexual reproduction, is responsible for the spread of most Bermuda grass. Bermudagrass (Cynodon dactylon) is a widely used warm‐season turfgrass species with superior stress tolerance except for cold. Combinations of herbicides and tilling were less effective. Agronomy Journal 62:285-287. [36], The increase in the amount of Cynodon dactylon due to cattle grazing is well documented. When grown as a turfgrass, mow regularly to a height of 3/4" to 1.5" tall, fertilize during the growing season (May to August) and use soil barriers to prevent spread into adjacent areas. [17] The cultivar and the environmental conditions greatly influence the reserve carbohydrate quantity and quality. [42] A late winter fire in Georgia drastically reduced the amount of Bermuda grass. 1981. Gould, F. 1951. [32] C. dactylon grew 1.5 to 2.4 times larger in mixed cultures than in mono-cultures, with a yield increase of 30% to 50% when grown with Acacia. In the spring when the temperature begins to increase new stolons elongate and aerial shoots sprout. Bermuda Grass (Cynodon Dactylon) The grass known by the scientific name Cynodon dactylon is, by far, the most widely used in both garden lawns and sports fields in some parts of the United States and Southern Europe.Not only is it easy to maintain but it will not be necessary to water it too often. 1085 pp. This grass produces good quality hay, grazing and foggage. Tall Timbers Fire Ecology Conference 11:175-199. Crop Science 3:5-9. Creeping stems, branched (digitate) flower heads. Information on both optimal manipulation and native competitor establishment must be specific for the problem site. comm., McWhorter pers. Bermuda grass is a mat-forming, medium- to fine-textured grass that is suitable for lawns and public areas. Results: C. dactylon extract exhibited significant cytotoxicity and arrested cell cycle in HNK-1 cells in a dose-dependent manner. The characteristic prostrate growth of Bermuda grass lasts for one to several months, early in the season, before flowering culms develop. Threats due to completely decayed residues should not be overlooked. Warm humid Transition zone Environment. Depending on the extent of coverage by the weed and on the site parameters a combination of the following manipulations may aid in controlling Bermuda grass: mowing and clipping, tilling and plowing, burning, shading, and chemical control. Read our Commitment to Diversity | Read our Privacy Statement. Biological activity of subterranean residues of. Humphrey, R. 1977. Herbicides are helpful in controlling Bermuda grass. Accepted name. Cynodon dactylon and Medicago sativa are two important species using in ecological restoration. Herbicide application in conjunction with tilling and desiccation may be the most effective control technique. [19] Inflorescences develop on the center shoot one and a half months after late spring planting. Carbohydrate reserves of grasses: a review. Cynodon dactylon (Linn.) form a strategic partnership called N.C. Knowledge of the extent of the underground rhizome and root system is important for manipulating the entire infested area; no additional measurements are required since the underground growth pattern parallels the aerial development. 4 pp. Warm humid Transition zone Environment. Control experiments were employed to test the effects of temperature and … Pers. [25][26] Air drying of one-node rhizome fragments for seven days resulted in the inhibition of sprouting and a 53% weight loss, however three-node rhizome fragments continued to sprout after seven days of desiccation. Hand hoeing is practical only where the concentration of Bermuda grass is low. [5][6][3] Bermuda grass, especially the cultivar Coastal, is extremely drought tolerant, however moisture significantly increases its growth rate. Bermuda grass grows best in average, dry to medium, well-drained soil in full sun and warm temperatures. Poor … Sources of variation in. Studies on the biotypes of, Newman, D. 1989. Rensburg, H. 1970. Cynodon dactylon and Acacia smallii were grown in mixed and mono-culture plots, with and without added fertilizer in order to study the competitive ability and mechanism of the two species. Skousen, J., C. Call, and R. Weaver. Nitrogen fertilizers decrease the amount of carbohydrate reserves; clipping increases the translocation of nitrogen from the soil to the roots and carbohydrate reserves are depleted during the above-ground utilization of nitrogen. Bermuda grass (Cynodon dactylon Pers.) 1987. White grubs are the most common insect problem. Effect of temperature, light, and nitrogen on growth and metabolism of 'tifgreen' Bermudagrass. Identifying Characteristics: Seed: s Seedling: h Mature Plant: c Method of Propagation: seed Life Cycle: w Similar Species: t References: Due to the variable outcome of burning, this method is not recommended for controlling Cynodon dactylon. (in collaboration with D.D. [18] In Mauritius, the carbohydrate reserves do not decrease in the late winter, instead they increase steadily from fall to spring, and then the pattern fluctuates the rest of the summer depending on the variety. Plants also recover quickly after fire and can tolerate at least several weeks of deep flooding (Cook et al., 2005). If appropriate, planting of tall plants between the invaded and non-invaded sites may prevent spreading into the exposed area. Dicotyledonous hosts restrict the multiplication of the plasmodiophorid vector and hence are considered as fortuitous hosts that may not contribute to perpetuation of virus inoculum. [30] However, the average area increase for Cynodon dactylon is only 0.9 m2 per month. 200. Couch/ Bermuda grass – Cynodon dactylon Couch/ Bermuda grass is a strong perennial grass which has both stolons and rhizomes. Chase, and D. Hedrick. There are several methods to control weeds. [9][3], In addition to high temperatures, Bermuda grass requires high light intensities. University of Arizona Press, Tucson, Arizona. 1959. Cooperative Extension prohibits discrimination and harassment on the basis of race, color, national origin, age, sex (including pregnancy), disability, religion, sexual orientation, gender identity, and veteran status. A more drastic control plan is necessary in sites heavily infested with Bermuda grass. [3] All biotypes, regardless of their fertility, produce inflorescences which range in height from 5 cm to 40 cm. [2], The common name for all the East African rhizomatous species of Cynodon is Bermuda grass. Presently no formal monitoring programs of Bermuda grass are known. Burton, G., J. Butler, and R. Hellwig. 1989. The plant is not frost or shade tolerant and the rhizomes and stolons are susceptible to desiccation. Root penetration, distribution, and activity in southern grasses measured by yields, drought symptoms, and P32 uptake. Yearly summer monitoring of Bermuda grass should determine whether the aerial extent is diminishing with the employed control measure. Grasses of southwestern United States. Manual of the grasses of the United States, second edition. [27] The importance of the allelopathic substances produced by Bermuda grass in the field is unclear. 557 pp. comm., Weigel pers.

Temperature factors limiting the spread of Cogongrass (, Cohn, E., O. VanAuken, and J. Bush. [18], Temperature affects the level of carbohydrates by altering the ratio between the respiration and photosynthetic rate, thus influencing the growth rate. B. Youngner, F. J. Nudge and J. J. Chatterton. Cynodon dactylon (L.) Pers (C. dactylon) is a widespread perennial herb found in the riparian zone of TGR, which can survive due to the vitality in dormancy state under periodic submergence [12–14]. The following is a description of the general life-cycle of Cynodon dactylon. [18] The depletion of carbohydrates is related to nitrogen concentrations. Family: Poaceae Life Cycle: Perennial Type: Grass Description: A warm-season species that spreads by aggressive rhizomes and stolons.It is often considered a weed in lawns and landscapes, but improved varieties are widely used for lawns, golf, and athletic turf due to its resiliency and tolerance of low mowing heights and traffic.
