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.

The genetics of meiotic chromosome pairing in Lolium temulentum x Lolium perenne tetraploids

Theoretical and Applied Genetics, 1985
The degree of preferential pairing of homologous chromosomes was estimated in a series of tetraploid hybrids of Lolium temulentum x Lolium perenne by means of cytological and genetic analyses. The correlations between the frequency of bivalents at first metaphase of meiosis in the hybrid tetraploids and the degree of preferential pairing calculated ...

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 ...

Aneuploids of perennial ryegrass (Lolium perenne)

Euphytica, 1982
Aneuploid plants of perennial ryegrass (Lolium perenne L.) with 2n=15 to 30 chromosomes were obtained by crossing a near-triploid (2n=3x+1=22) with a diploid or on open-pollination with diploids and tetraploids. Aneuploids occurred with a frequency of 83% in near triploid × diploid progeny and 92% on open-pollination with diploid and tetraploid plants.

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.

The chemical composition of the surface wax of lolium perenne

Phytochemistry, 1969
Abstract The surface wax of Lolium perenne has been separated into three fractions by application of thin-layer and column chromatography using silica gel. Fraction I consists entirely of normal hydrocarbons with C 27 , C 29 , C 31 , and C 33 , predominating.

Photosynthesis and Photorespiration inLolium multiflorumandLolium perenne

Journal of Experimental Botany, 1971
The response of net photosynthesis to changing light-flux density by leaves of Lolium multiflorum (S. 22) and L. perenne (S. 321) is more adequately described by current models when a term allowing for photorespiration is included. The magnitude of this term was determined from the changes in the slope of the light-response curves for net ...

Lignin-carbohydrate complexes from Lolium perenne

Phytochemistry, 1974
Abstract Lignin-carbohydrate and lignin-hemicellulose complexes were extracted sequentially from four varieties of Lolium perenne which had previously ...

Hybrid production in Lolium perenne based on incompatibility

Euphytica, 1993
SI-hybrids were produced by crossing 30 partially inbred lines in 3 sets of 5×5 factorial crosses. Annual dry matter yields from 3 successive years and 2 locations were on average 9.5 T/ha for the hybrids compared to 8.9 T/ha for their parental lines, with the best hybrid yielding 10.3 T/ha. Heterosis was up to 20%.

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
