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 perenne, showing ligule and ribbed leaf
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 ...
Typical vernalization temperatures are between 1 and 7 degrees Celsius (34 and 45 degrees Fahrenheit). [ 4 ] For many perennial plants , such as fruit tree species, a period of cold is needed first to induce dormancy and then later, after the requisite period, re-emerge from that dormancy prior to flowering.
Common names by which it is known include annual ryegrass, a name also given to Italian ryegrass (Lolium multiflorum), rigid ryegrass, stiff darnel, Swiss ryegrass and Wimmera ryegrass. [1] It is a native of southern Europe, northern Africa, the Middle East and the Indian subcontinent and is grown as a forage crop, particularly in Australia ...
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.
They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, [6] wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. [ citation needed ] Some members of the Poaceae are used as building materials ( bamboo , thatch , and straw ); others can provide a source of biofuel , primarily via ...
The seeds are 3–6 mm (1 ⁄ 8 – 1 ⁄ 4 in) long and up to 1.5 mm (1 ⁄ 16 in) wide, and are developed from a single-flowered spikelet. Both glumes are present and well developed. When ripe, the seeds sometimes take on a pink or dull-purple tinge, and turn golden brown with the foliage of the plant in the fall.
