Effects of thermal and cycloheximide pre‐treatments on light dependent‐necrosis formation by Pyricularia oryzae toxin(s) on cv. Sekiguchi‐asahi were investigated. Thermal treatments of rice leaves at 55 °C for 10 and 15 sec significantly suppressed leaf necrosis formation. Such heat‐induced insensitivity of rice leaves to toxin(s) was greater at a thermal treatment of 55 °C for 15 sec than that of 55 °C for 10 sec. Cycloheximide pre‐treatment also suppressed leaf necrosis formation under light.
