Abstract

Drops of conidia suspension of Piricularia oryzae were mounted on the detached leaf pieces of rice plant, at the points pricked by capillary glass tube, and kept at 25-28°C for 24 hrs. in the moist chamber.
These drops were then collected and centrifuged for 20minutes by 3000rpm. The supernatant of these drops showed strong inhibiting action against the germination of conidia of this fungus. The active principle, phytoalexin of Müller, is considered to be produced by the host plant as a result of interaction between rice plant and the blast fungus P. oyyzae.
In the experiment to see the quantitative difference of phytoalexin prodcution between resistant or susceptible varieties of rice plant to blast fungus, it was shown that phytoalexin was more vigorously produced in the resistant varieties (Kameji and Norin No. 22)than in the susceptible ones (Asahi and Omachi).
