Stickstoffausnutzungsvermögen von Lolium perenne und Lolium multiflorum‐Sorten
Journal of Agronomy and Crop Science, 1988Abstract 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.

Isolation, Culture and Regeneration of Lolium Perenne and Lolium Multiflorum Protoplasts
1988For 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.

SUMMARYA previously unrecorded virus with isometric particles 27 nm diameter, has been isolated from Lolium perenne L. and Cynosurus cristatus L. from Eire and from C. cristatus from Yorkshire, and named lolium mottle virus (LMV). The virus could be inoculated into cultivars of wheat, oats, barley and rye, and Lagurus ovatus L.

Chromosoma, 1976
Cytomixis is a spontaneous process occurring through the formation of cytoplasmic bridges between adjacent pollen mother cells. This phenomenon was observed in the pollen mother cells of 3 genotypes of Lolium perenne which had been subjected to directional selection for productivity of green material.

Photosynthesis and Photorespiration inLolium multiflorumandLolium perenne
Journal of Experimental Botany, 1971The 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 ...

Chromosoma, 1978
Eighteen plants displaying varying degrees of asynapsis ranging from weak to very strong were found among four out of six populations of Lolium perenne L. (2n=14) which had been subjected to three cycles of directional phenotypic selection for productivity of green material.

The genetics of meiotic chromosome pairing in Lolium temulentum x Lolium perenne tetraploids
Theoretical and Applied Genetics, 1985The 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 ...

Theoretical and Applied Genetics, 1982
Populations of induced polyploids invariably contain a substantial proportion of aneuploid individuals. A model is described which can predict the level of aneuploidy in successive generations of a closed population of Lolium tetraploids. The results demonstrate clearly that the proportion of aneuploid individuals increases sharply for two to three ...

Australian Journal of Botany, 1983
The genus Lolium is represented in Australia by the following five species: L. perenne, L. multiflorum, L. rigidum, L. loliaceum and L. temulentum. L. remotum is probably extinct in Australia as it has been found only associated with flax crops which are no longer grown locally.
