Growth Responses to Air-and Soil-Temperatures of Orchardgrass and Perennial Ryegrass

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...

Dry Matter Production of Orchardgrass and Perennial Ryegrass at Five Irrigation Levels

cultivar Paiute, which originated from a single plant introduction (PI-109072) (Alderson and Sharp, 1994), Within the Great Basin, availability of irrigation water throughout very little breeding has been done to develop improved the growing season is the limiting factor in the development of improved pastures. The choice of species and their water requirements cultivars of cool-season perennia...

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...
