Fructan and cryoprotection in ryegrass (Lolium perenne L.)

New Phytologist, 1990
summaryChanges 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.)

2006
A 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 ...

Isolation, Culture and Regeneration of Lolium Perenne and Lolium Multiflorum Protoplasts

1988
For the application of most genetic manipulation techniques a reliable system for plant regeneration from single cells and protoplasts is a prerequisite. In the Gramineae plant regeneration from protoplasts has been achieved only when morphogenically competent cell suspensions were used for protoplast isolation.

Stickstoffausnutzungsvermögen von Lolium perenne und Lolium multiflorum‐Sorten

Journal of Agronomy and Crop Science, 1988
Abstract Selection for improved nitrogen‐utilization in Lolium In a 3‐year study the responses of 14 Lolium perenne‐varieties and 14 of Lolium multiflorum to different nitrogen fertilization (75, 150, 300 kg N/ha) were investigated. The varieties were classificated into four types of nitrogen utilization. “Low input varieties” can be found in type III.

Stability of Lolium perenne extract.

Annals of allergy, 1984
The stability of Lolium perenne extract was studied during a year in different conditions of storage. The changes of allergen activity were measured periodically by both in vivo and in vitro techniques, and structural modifications were examined by polyacrylamide gel electrophoresis and isoelectric focusing. Lyophilised extracts did not show any change

The effect of copper on Lolium perenne seedlings

Chemosphere, 1989
The 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.

Genotype–Environment Interactions in Lolium perenne

Nature, 1955
UNTIL 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,

Selection for seed yield in lolium perenne L.

1981
The results of one cycle of phenotypic recurrent selection within a population of Lolium perenne showed that: (1) Selection for high seed yield led from 7.14 g/plant (unselected control) to 14.67 g/plant with a realized heritability of 40%; (2) Selection for 1000-seed weight gave an absolute response of 156.4 mg (10.1% of the unselected control) with a

A possible virus disease in Lolium perenne

Euphytica, 1956
Two 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

Über einige Aminosäuren in Lolium perenne

Recueil des Travaux Chimiques des Pays-Bas, 1943
AbstractIn Lolium perenne wurden das freie Arginin, Tyrosin und Tryptophan bestimmt; es wurde gefunden, dass ein konstantes, vom Alter des Grases unabhängiges, Verhältnis zwischen diesen drei freien Aminosäuren besteht; durchschnittlich: Auch zwischen dem im Eiweiss gebundenen Arginin, Tyrosin und Tryptophan besteht ein konstantes und gleiches ...
