Lolium perenne, common name perennial ryegrass, [1] English ryegrass, winter ryegrass, or ray grass, is a grass from the family Poaceae. It is native to Europe, Asia and northern Africa, but is widely cultivated and naturalised around the world.
Leymus chinensis shows 47% germination under variable temperatures ranging from 10 to 30 °C. De-husking (removing outer-covering of seeds) at constant temperature was shown to also improve germination. [3] The effects of light have had an interesting effect on the germination of Leymus chinensis. The plants were assessed according to three ...
Lolium multiflorum (Italian rye-grass, [2] annual ryegrass) is a ryegrass native to temperate Europe, though its precise native range is unknown. [3] It is a herbaceous annual, biennial, or perennial grass that is grown for silage, and as a cover crop. [4] [5] It is also grown as an ornamental grass.
There is a large range of cultivars. The primary species found worldwide and used both for lawns and as a forage crop is perennial ryegrass ( Lolium perenne ). Like many cool-season grasses of the Poaceae, it harbors a symbiotic fungal endophyte , either Epichloë or its close relative Neotyphodium , both of which are members of the fungal ...
Growing degrees (GDs) is defined as the number of temperature degrees above a certain threshold base temperature, which varies among crop species. The base temperature is that temperature below which plant growth is zero. GDs are calculated each day as maximum temperature plus the minimum temperature divided by 2, minus the base temperature.
Tall fescue is a long-lived tuft-forming perennial with erect to spreading hollow flowering stems up to about 165 cm (5'6") tall (exceptionally up to 200 cm) which are hairless (glabrous), including the leaf sheaths, but with a short (1.5 mm) ligule and slightly hairy (ciliate) pointed auricles that can wrap slightly around the stem.
Annual grasslands are dominated by non-native annual grasses and forbs, with a few native perennial grass species present. These grasslands are subject to seasonal and yearly variations in species composition and productivity, which are largely controlled by the timing and amount of precipitation and temperature.
Perennial cool-season – orchardgrass (cocksfoot, Dactylis glomerata), fescue (Festuca spp.), Kentucky bluegrass and perennial ryegrass (Lolium perenne) Annual warm-season – maize, sudangrass, and pearl millet; Perennial warm-season – big bluestem, Indiangrass, Bermudagrass and switchgrass.
