Sampling ryegrass to assess the risk of annual ryegrass toxicity

Australian Veterinary Journal, 1993
SUMMARY Most stock losses caused by annual ryegrass toxicity occur because stockowners unknowingly allow their stock to graze annual ryegrass (Lollum rigidum) Infected with the bacterium Clavlbacter toxicus. To help stockowners avoid losses we have developed criteria for a testing service to determine the risk of poisoning before the pasture is grazed.

Trisomics of ryegrass and their transmission

Theoretical and Applied Genetics, 1981
Primary trisomics of perennial ryegrass, Lolium perenne L., were studied for meiotic behaviour, fertility, morphology and trisome transmission. Trisomics differed from each other in mean meiotic association, pollen fertility, seed set and morphology. The combined cytomorphological data suggested that the investigated trisomic plants included trisomes 2

The role of perennial ryegrass endophyte in Italian ryegrass

NZGA: Research and Practice Series, 2006
Italian ryegrass (Lolium multiflorum) and short-term hybrid ryegrass (L. boucheanum) have reliable establishment and high cool season growth, but varying persistence after the first summer. In Northland, there is increased stress on ryegrass from invertebrate insect attack.

Ryegrass Staggers: The Presence of Lolitrem Neurotoxins in Perennial Ryegrass Seed

New Zealand Veterinary Journal, 1982
Abstract Extract Sir:- Recently, two potent neurotoxins named lolitrem A and lolitrem B were isolated from herbage collected from pastures on which the livestock disorder ryegrass staggers (RGS) occurred. et al.(1) We now wish to report that samples of perennial rygrass (Loliun yeretzrze L.) seed obtained from several locations in New Zealand contained

Trisomics and aneuploids of ryegrass

Theoretical and Applied Genetics, 1972
Primary trisomics (2 n + 1 = 15), double trisomics (2 n + 1 + 1 = 16) and aneuploids with 24 to 30 chromosomes, as well as a diploid and tetraploids, were found in the progeny of a hypertriploid (2 n = 22) plant of perennial ryegrass, Lolium perenne L.

Prevention of Ryegrass Staggers

New Zealand Veterinary Journal, 1982
Abstract Extract Sir:- We recently obtained some interesting results in significantly reducing ryegrass staggers (RGS) in young Friesian calves by preventative drenching with Nutrimol (liquid seaweed animal health aid).

Effect of ryegrass mosaic virus on the quality of perennial ryegrass

Annals of Applied Biology, 1979
SUMMARYIn 1976 fields of perennial ryegrass located on two farms in the west of Scotland were found to be far more severely and extensively infected by ryegrass mosaic virus (RMV) than had been seen in earlier surveys of ryegrass fields in 1972 and 1973.The chemical analysis of samples of ryegrass from 10 of the fields examined in 1976 showed that RMV ...

Haploidy in ryegrass

1997
Both Lolium perenne and L. multiflorum are strong outbreeders that exhibit severe inbreeding depression (Bean & Yok-Hwa, 1972; Matzk, 1974) and possess a strict gametophytic self-incompatibility system which involves two major gene loci with modification by the genetic background (Lawrence et al., 1983).
