The Dense Perennial Grass

English ryegrass (Lolium perenne) is a dense sod-forming perennial plant from the grass family (Poaceae).

English ryegrass is both natural and sown in the Netherlands. Netherlands lies in the heart of English ryegrass genes. Dutch breeding companies have created numerous varieties. It is not a very advanced state of high feed nutritious grass. English ryegrass is also resistant to entry of humans and animals. It is sown in pastures, lawns and play sports. In the latter two cases, not a sharp mower sometimes difficult to browse through the large vascular bundles in the veins, which are called flags arise.

The name dates back to English ryegrass grass seed that was imported from England. The earliest cultivation of grass already took place in early 1600 in Oxfordshire in England and spread rapidly in England strongly. This seed was on the mainland under the name English ryegrass marketed.

The plant is 30-60 cm tall with erect, smooth stems. The foliage is light green, hairless and shiny greasy. The stabbing veins well above the leaf surface off. It is up to 20 cm long. The leaves are in a young stage folded along the midrib. The sheath at the base is often pink. The tongue (ligule) is annular and 2 mm high.

Inflorescence a spike with a flat back and bent back flat spindle. The spikelets are in packages of eight to ten flowers are sessile and ovoid, and flattened. The number of packets can vary from 18 to 24 per spike. These are alternately arranged on either side of the axis in a small erosion of the road. The kelkkafjes are about 1.5 times as long as the husk. The lemma (lower husk) is about needle.

English ryegrass of different types are distinguished on the flowering time. The earliest type ("early hay type) blooms from mid May to late May The late type (pasture type) flowers in the first half of June. After mowing or grazing only the type of hay early again in bloom.

The fruit is a fruit crop.

The shape of the plants vary in the stage of vegetative propagation is very flat to very upright habit. Early hay types have a more upright growing form and pasture types are more flat-growing forms, especially in plants in old pastures. Grazing by these types of surviving because of this type may be relatively less grazed.

The types of lawn chairs and remain low strongly (that is, they get to the ground shoots). By tillering you get a nice thick turf with good standing.

English ryegrass in late summer can be especially strongly affected by crown rust (Puccinia lolii coronota f.). There are large racial differences in resistance to crown rust.
