The effect of copper on Lolium perenne seedlings
Chemosphere, 1989The present study looks at the effects of copper on perenial ryegrass seedlings that have been grown in hydroponic solutions and the uptake of some essential elements.

A novel nanoparticulate adjuvant for immunotherapy with Lolium perenne
Journal of Immunological Methods, 2009Specific immunotherapy implies certain drawbacks which could be minimized by the use of appropriate adjuvants, capable of amplifying the right immune response with minimal side effects. In this context, previous studies of our group have demonstrated the adjuvant capacity of Gantrez AN nanoparticles, which can effectively enhance the immune response ...

A possible virus disease in Lolium perenne
Euphytica, 1956Two types of abnormal plants have been observed in clonal plantations of perennial ryegrass. Plants of the first group were characterized in early spring by a dense dwarfed growth of distorted blue-green leaves. Those of the second group became recognizable later in the season, because of their somewhat stunted growth and the yellow, orange or pale-red

Chromosome Size in Lolium temulentum and L. perenne
Nature, 1958MORPHOLOGICALLY the grasses Lolium perenne and L. temulentum are markedly dissimilar and easily distinguished from one another. They differ also in habit and in their breeding system; the former is perennial and outbreeding, while the latter is an annual and inbreeding. Despite their divergencies in form and habit, the species can, however, be crossed,

Fructan and cryoprotection in ryegrass (Lolium perenne L.)
New Phytologist, 1990summaryChanges in carbohydrate content and composition of ryegrass (Lolium perenne L.) cv. Reveille field‐grown in Normandy were investigated from May 1987 to May 1988. During the winter period, the concentrations of high DP (degree of polymerization) fructan were the lowest whilst those of ethanol‐soluble carbohydrates were the highest.

Perennial Ryegrass (Lolium perenne L.)
2006A protocol that facilitates rapid establishment of Agrobacterium-mediated transformation for perennial ryegrass is described. The synthetic green fluorescent protein (sgfpS65T) reporter gene is introduced in combination with the nptII selectable marker gene into axillary bud derived embryogenic calli of perennial ryegrass (Lolium perenne L.) by co ...

Genotype–Environment Interactions in Lolium perenne
Nature, 1955UNTIL recently, the importance of genotype–environment interactions, though generally recognized by plant and animal breeders, has been largely neglected in most quantitative studies. Despite their possible removal by scaling1, theoretical objections to this procedure have been made and these objections are underlined by recent results in, for example,

Subtribe‐specific monoclonal antibodies to Lolium perenne
Clinical & Experimental Allergy, 1999Background and objectivesThe ability to measure personal exposure to airborne grass pollen is important in the understanding of allergic diseases. Visual identification is time consuming and it is difficult to distinguish between many grass pollens morphologically.

The genetic control of incompatibility in Lolium perenne L.
Genetica, 1971An examination of the incompatibility mechanism of Lolium perenne using the pollen stigma reaction has revealed that no precise one or two locus system is operative in this species.
