Investigation into plant characters affecting the competitive ability of perennial ryegrass (Lolium perenne L.).

Abstract

In a number of pot and tray experiments in soil and in sol. culture the same clone of 6 perennial ryegrass clones tested was always the most competitive both in the vegetative phase and the reproductive phase, while another clone always showed the least competitive ability. The most competitive clone had the relatively greatest root system, the least competitive clone the relatively smallest root system. The soluble carbohydrate content in tillers and stubbles of the clones did not yield any evidence on competitive ability. (Abstract retrieved from CAB Abstracts by CABI’s permission)
