Seed production studies on perennial ryegrass, timothy and prairie grass. 1. Effect of tiller age on tiller survival, ear emergence and seedhead components


, : Seed production studies on perennial ryegrass, timothy and prairie grass. 1. Effect of tiller age on tiller survival, ear emergence and seedhead components. Journal of the British Grassland Society 20(1): 63-71

A 2-year study involving tiller identification according to month of origin enabled the contribution of individual tillers of perennial ryegrass Grasslands Ruanui, timothy Grasslands Kathu and a local New Zealand ecotype of Bromus unioloides to be determined at seed harvest. The distribution of seed-heads in different arbitrary emergence groups was also determined so as to allow analysis of individual seed-head components within each group.
