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.
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 ...
Bouteloua dactyloides is a perennial plant that spreads by stolons (runners). [3] A plant may extend stolons outward to reach a length of 15 to 45 centimetres (6 to 18 in) by the end of a growing season. [4] In ideal experimental conditions stolons may grow as much as 5.71 centimetres (2.25 in) per day. [5]
Grasses may be annual or perennial herbs, [8]: 10 generally with the following characteristics (the image gallery can be used for reference): The stems of grasses, called culms, are usually cylindrical (more rarely flattened, but not 3-angled) and are hollow, plugged at the nodes, where the leaves are attached.
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 ...
The close link between soil carbon and underground biomass leads to similar responses of these carbon pools to fluctuations in annual precipitation and temperature on a broad spatial scale. Because plant productivity is limited by grassland precipitation, carbon stocks are highest in regions where precipitation is heaviest, such as the high ...
Thinopyrum intermedium, known commonly as intermediate wheatgrass, [1] is a sod-forming perennial grass in the Triticeae tribe of Pooideae native to Europe and Western Asia. [2] It is part of a group of plants commonly called wheatgrasses because of the similarity of their seed heads or ears to common wheat.
