Fungal development, respiration and activity of oxidative enzymes in rice plants inoculated with Pyricularia oryzae in both compatible and incompatible combinations



Fungal development, respiration and activity of oxidative enzymes in rice plants inoculated with Pyricularia oryzae in both compatible and incompatible combinations



Korean Journal of Plant Protection 21(3): 113-122



Appressorial formation of P. oryzae on leaves showed no marked difference between highly resistant Tongil and susceptible Norin No.6. Race N-2 of the fungus penetrated directly into motor cells of the latter and spreading hyphae then developed, in contrast to Tongil where no further hyphal extension occurred after penetration. Infected tissues of Tongil discoloured rapidly, and the percentage of discoloured cells was higher than in susceptible cultivars.
