摘要：

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-degrees-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-degrees-C for 15 sec than that of 55-degrees-C for 10 sec. Cycloheximide pre-treatment also suppressed leaf necrosis formation under light.
