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 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.

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.
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.
In 1857 an American agriculturist John Hancock Klippart, Secretary of the Ohio Board of Agriculture, reported the importance and effect of winter temperature on the germination of wheat. One of the most significant works was by a German plant physiologist Gustav Gassner who made a detailed discussion in his 1918 paper.
Elymus elymoides is a perennial bunch grass growing to around 0.5 metres (1 + 1 ⁄ 2 feet) in height. Its erect solid stems have flat or rolled leaf blades. The inflorescence is up to 15 centimetres (6 inches) long and somewhat stiff and erect, with spikelets 1 or 2 cm long not counting the awn, which may be 9 cm (3 + 1 ⁄ 2 in) long and sticks straight out at maturity, making the ...
The germination percentage is simply the proportion of seeds that germinate from all seeds subject to the right conditions for growth. The germination rate is the length of time it takes for the seeds to germinate. Germination percentages and rates are affected by seed viability, dormancy and environmental effects that impact on the seed and ...
