Lolium Endophyte and Sheep Performance on Perennial Ryegrass Cultivars
Some effects of l&m endophyte (Acremonium lolioe) on sheep production were evaluated using pure swards of h igh (SO%>) and low (< 5%) endophyte Nui and Ar ik i ryegrass. The proportion of infected t i l lers in high endophyte treatments increased by 19% in 15 months. Ryegrass staggers occurred on both high endophyte ryegrasses being sl ight ly worse on Nui . The peak ryegrass staggers outbreak ...
متن کاملSimulating perennial ryegrass cutting
Perennial ryegrass is one of the most commonly cultivated forage species in Europe, where grazing and mowing (cutting) are used to manage this resource. Cutting can be characterized by its intensity (height) and its frequency. Combinations of these two factors affect mono-species grasslands productivity and could also modify the genotypic composition of heterogeneous populations. Indeed, the hi...
متن کاملGrowth Characteristics of Perennial Ryegrass
Mature perennial ryegrass plants in pastures persist through the asexual reproduction of the tiller. Leaves are initiated from the flanks of the tiller stem apex. Generally, two leaves arc growing on a tiller at any one time. New tiller buds may arise from the axils of mature leaves depending on environmental conditions. Flowering results from a physiological change at the stem apex, which then...
متن کاملHeat Tolerance Screening of Field-Grown Cultivars of Kentucky Bluegrass and Perennial Ryegrass
The quality of cool-season turfgrasses frequently declines during periods of high temperature stress. Simple tests are needed to rapidly identify heat tolerant germplasm for incorporation into breeding pro grams. Facilitative screening tests have been devised, however, in the few studies that have been performed only immature and green house or growth chamber-grown plants have been evaluated....
متن کاملImproved Winter Hardiness In TurfType Perennial Ryegrass?
The market for turf-type perennial ryegrass (Lolium perenne) continues to grow with over $70 million in seed sales in 1994. Breeders in private companies are capitalizing on this increasing ryegrass popularity by continuing to make improvements in turf quality traits such as color, density, texture, mowability and disease resistance. However, all current improved turf-type cultivars do not have...
