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.
Rye (Secale cereale) is a grass grown extensively as a grain, a cover crop and a forage crop. It is grown principally in an area from Eastern and Northern Europe into Russia. It is much more tolerant of cold weather and poor soil than other cereals, making it useful in those regions; its vigorous growth suppresses weeds and provides abundant forage for animals early in the yea
Leymus chinensis is a perennial plant that is normally 40–90 cm tall and is native to northern China. [2] It is a plant that can potentially be used as a food source in future generations. Scientists have tested the effects of various stimuli on Leymus chinensis. If optimum conditions for the growth of this plant are discovered, then this ...
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.
It has been adapted by and to other countries (such as Canada) in various forms. A plant may be described as "hardy to zone 10": this means that the plant can withstand a minimum temperature of 30 to 40 °F (−1.1 to 4.4 °C). Unless otherwise specified, in American contexts "hardiness zone" or simply "zone" usually refers to the USDA scale.
Leymus condensatus also commonly referred to as [2] Canyon Prince is a type of wild rye that is part of the Poaceae (Grass Family). It grows in bunches or clumps, a bunch grass, stays green all year, and has a distinctive silver blue foliage.
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.
Once the plant has matured, the manystem wild rye grass can live a long life. The surroundings of the mature Leymus multicaulis can influence the lifespan of the plant. For example, if the mature plant is in an area with high concentration of nitrogen, it is in a healthy environment and will have a longer lifespan. If there are high ...
