Hybridization between perennial ryegrass and Italian ryegrass in naturalized Japanese populations

Grassland Science, 2008
AbstractIntroduced Lolium species, including perennial ryegrass (Lolium perenne) and Italian ryegrass (Lolium multiflorum), have been widely utilized in Japan for forage, turf and soil conservation. These ryegrasses have escaped from cultivated areas and become naturalized, and this has become a serious issue in recent years.

THE CRUDE‐PROTEIN CONTENT OF ITALIAN RYEGRASS

Grass and Forage Science, 1961
The effects of variety, date of cutting flush growth and level of nitrogenous manuring on the crude‐protein content of Italian ryegrass were studied on plots cut five times in 1958.Raising the level of nitrogenous fertilizer from 174 lb. to 348 1b. N/acre reduced the percentage of dry matter from 0·5 to 2·0 and increased the percentage of crude protein

Chlorotic Streaking in Italian Ryegrass

Plant Pathology, 1974
SUMMARY A virus apparently indistinguishable from the ryegrass.chlorotic streak virus in New Zealand has been found in Britain where it appears to be similar to, if not identical with, isolates of barley yellow dwarf virus transmitted specifically by Rhopalosiphum padi .

Hybrids between tetraploid Italian and perennial ryegrass

Theoretical and Applied Genetics, 1977
Hybridization frequency was investigated between tetraploid perennial and Italian ryegrass (Lolium perenne X multiflorum) without emasculation by using genetic markers. The Italian phenotypes, fluorescentroots and awned florets, were dominant. About 82% of the plants in perennial X Italian and nearly 93 % of the plants in the reciprocal crosses were ...

Italian ryegrass as a perennial fodder crop

Proceedings of the Annual Congresses of the Grassland Society of Southern Africa, 1976
Italian ryegrass (Lolium multiflorum Lam.) may be re-established from seedfall if the appropriate management practices are applied, and may thus function as a perennial fodder crop. Annual seedbed preparation and seeding are eliminated in this way.Keywords: botany; fodder; grasses; italian ryegrass; lolium multiflorum; management; ryegrass;

Identification of companion small grains for midmar Italian ryegrass

Journal of the Grassland Society of Southern Africa, 1988
In a preliminary investigation four small grain species, oats (Avena sativa) rye (Secalae cereale), wheat (Triticum aestivum) and triticale (Triticum x secalae) were planted alone and in combination with Lolium multiflorum cv Midmar under irrigation. The dry matter (DM) yield of Midmar was also compared to that of four other annual ryegrass cultivars ...

Identification of companion legumes for midmar Italian ryegrass

Journal of the Grassland Society of Southern Africa, 1987
In a preliminary investigation seven legumes were planted alone and in combination with Lolium multiflorum cv. Midmar. The pure stands of legumes were harvested at either four, five of six week cutting intervals, while the pure stands of Lolium multiflorum and the ryegrass/legume mixtures received in addition to the cutting treatments 0, 200 of 400 kg ...

Tetraploid Italian ryegrass (Lolium multiflorum Lam.)

Euphytica, 1958
1. Some preliminary experiments are described with C2- and C3-generations of tetraploid Italian ryegrass. In all cases the tetraploids had a lower dry matter content than the diploids. 2. A C3-generation produced by mass selection equalled or surpassed the diploid mother strains in dry matter yield in some small experiments on several ...

NITROGENOUS FERTILIZATION OF ITALIAN RYEGRASS IN SPRING

Grass and Forage Science, 1968
A series of experiments in eastern Scotland, carried out over a 7–year period, on the application of N fertilizers to Italian ryegrass for producing early spring grass, indicated that maximum yields are likely to be produced if the fertilizer is applied not later than the middle of March in most seasons.

Nitrogen requirements for italian ryegrass seed production

1993
Italian ryegrass cv. Grasslands Tama was grown outside in pots given solutions containing concentrations of nitrogen (N) ranging from 32.5 to 910 μg/g; all other nutrients were adequately supplied. Plants were harvested during active vegetative growth (spring) or when seed was ripe.
