Influence of the ryegrass endophyte (Neotyphodium lolii) in a cool moist environment IV. Plant parasitic nematodes

摘要

Abstract The influence of the ryegrass endophyte on plant‐parasitic nematodes in a cool moist environment in New Zealand was evaluated in a pot and a grazing experiment. Nematodes of the genus Paratylenchus made up 99% of the fraction of plant‐parasitic nematodes and their numbers were higher (P > 0.05) on endophyte‐free plants in the pot experiment and in fields containing mono‐cultures of endophyte‐free ryegrass. Nui endophyte‐free plants and pastures had higher dry matter yields than endophyte‐infected plants and pastures. The effect of endophyte strains on nematodes was inconclusive.
