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.
[2] [3] It is often called ryegrass, but this term is sometimes used to refer to grasses in other genera. They are characterized by bunch-like growth habits. Lolium is native to Europe , Asia and northern Africa , as well as being cultivated and naturalized in Australia , the Americas , and various oceanic islands.
The seed germinates quickly (1–7 days) depending on temperature. [5]: 2 and it often achieves full ground cover within three months of sowing. [5]: 2 This too is good for farmers when it comes to covering bare soil. The fact that Chloris gayana can grow quickly means that farmers could use it to protect the soil from eroding.
The development of perennial grains could improve the sustainability of agriculture. [8] [9] [1] [5] In contrast to annual systems, perennial systems involve plants with deep, long lived roots. A perennial system is not dependent on tilling and could reduce the dependence on chemical applications, build soil health, and sequester carbon. [1] [8]
Unfortunately, a large amount of red-listed species are specialists of semi-natural grasslands and are affected by the landscape change due to agriculture of the last century. [15] The original wild-plant communities having been replaced by sown monocultures of cultivated varieties of grasses and clovers, such as perennial ryegrass and white ...
