Smooth Crabgrass Control in Perennial Ryegrass with Repeated Low Fenoxaprop Application Rates

Simulating 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...

Growth 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...

The effects of maleic hydrazide on growth control of perennial ryegrass (lolium perenne L.CV. yarandi)

Improved 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...

Identification of genes associated with cold acclimation in perennial ryegrass.

Cold acclimation dramatically increases freezing tolerance in many temperate plant species. An understanding of cold acclimation is important for extending adaptation areas of perennial ryegrass. Freezing tolerance is greatly increased in perennial ryegrass cv. 'Caddyshack' after cold acclimation. Genes differentially regulated during cold acclimation were identified by analyzing the abundance ...
