Germination Responses of Ryegrass (Annual vs. Perennial) Seed to the Interactive Effects of Temperature and Salt-Alkali Stress

Frontiers in Plant Science, 2018
Ryegrass is considered a useful grass species for forage production and turf purposes. Annual ryegrass (Lolium multiflorum Lam.) and perennial ryegrass (Lolium perenne L.)are two species of ryegrass with similar genomes. So far, little information exists

The resistance of the perennial ryegrass cultivar Endura to ryegrass mosaic virus

Annals of Applied Biology, 1980
SUMMARYThe perennial ryegrass cv. Endura is particularly resistant to infection with two ryegrass mosaic virus isolates, RMV‐Roth and RMV‐Sax. A few plants appeared immune to RMV‐Roth but were infected by RMV‐Sax. Two plants that developed only mild symptoms after infection with RMV‐Roth contained few virus particles, but passage through these ...

Evaluation of the Relationship between Cultivar, Endophyte and Environment on the Expression of Persistence in Perennial Ryegrass Populations Using High-Throughput Phenotyping

Agronomy, 2023
Perennial ryegrass (Lolium perenne L.) is a commonly grown pasture species in temperate agriculture, mainly serving as a primary energy source for dairy cows. However, its limited persistence often leads to missed production potential and early resowing,

Manipulation of the pre-partum diet of dairy cows to promote early adaptation to perennial ryegrass herbage

Irish Journal of Agricultural and Food Research, 2021
The diet of dairy cows in Ireland traditionally changes abruptly from predominantly pasture silage before calving to grazed perennial ryegrass immediately after calving.

Evaluation of competitive ability of perennial ryegrass in mixtures with red clover and lucerne subjected to different levels of N [PDF]

Biotechnology in Animal Husbandry, 2018
Grass-legume mixtures represent complex communities of grasses and legumes that make better use of resources and have a number of positive traits in comparison to monoculture.

Scarabaeid Larvae- and Herbicide-Resistant Transgenic Perennial Ryegrass (Lolium perenne L.) Obtained by Agrobacterium tumefaciens-Mediated Transformation of cry8Ca2, cry8Ga and bar Genes

Journal of Integrative Agriculture, 2012
Insect pest and weeds are two major problems for forage and turf grasses. In this study, scarab larvae- and herbicideresistant transgenic perennial ryegrass (Lolium perenne L.) was obtained by transforming it with cry and bar genes simultaneously via the

Seed lipid profiles of perennial ryegrass: Global patterns and differentiation of ryegrass cultivars and Epichloë endophytes

Grassland Research, EarlyView.
Seed lipid profiles from three ryegrass cultivars infected with AR501 show distinct changes in the medium‐chain diacylglycerols, triacylglycerols and sphingolipids. The differential peal LN745.5052_5.78 can be identified as PG 16:0_18:2 with the supporting ms2 fragmentation spectrum. Abstract Background Forage perennial ryegrass (Lolium perenne L.) has

Can irrigating more frequently mitigate detrimental heat wave effects on perennial ryegrass growth and persistence?

, 2020
Heat waves are problematic for grazing livestock systems in regions dependant on temperate (cool-season) pasture species, owing to the often minimal heat tolerance (thermotolerance) of these pastures. A field experiment in north-west Tasmania, Australia,

Optimising Sulphur Fertilisation in Ryegrass–White Clover Swards Reduces Leached Nitrate Nitrogen Losses, While Increasing Plant Yield and Nitrogen Off‐Take

Journal of Plant Nutrition and Soil Science, EarlyView.
The inclusion of sulphur at two inorganic nitrogen rates (0 and 150 kg N ha−1) improves plant productivity in a ryegrass–white clover sward and reduces nitrate‐N loss to groundwater in a free‐draining sandy loam soil. ABSTRACT Background Reducing nitrogen (N) losses to water, lessening reliance on inorganic fertiliser and maintaining agricultural ...

Comparison of herbage yield, nutritive value and ensilability traits of three ryegrass species evaluated for the Irish Recommended List

Irish Journal of Agricultural and Food Research, 2015
This study examined 169 of the newest varieties of three ryegrass species, perennial (Lolium perenne L.), Italian (Lolium multiflorum Lam.) and hybrid (Lolium boucheanum Kunth), from Recommended List trials in Ireland. The traits examined were yield, dry
