Abstract

The present invention provides an agent for inducing stress tolerance in plants which exhibits excellent stress tolerance inducing action on plants; a method for reducing a decrease in rice quality; asummer heat-mitigating growth method for turf grass; a method for inhibiting spindly growth of seedlings; a method for inhibiting growth failure of flowers; a method for reducing deterioration in thequality of fruit trees; and a method for reducing deterioration in the quality of vegetables. This agent for inducing stress tolerance in plants includes, as an active ingredient, a compound having aquinone skeleton represented by general formula (I) (in general formula (I): R1 represents hydrogen, a hydroxyl group, an amino group, a halogen, an alkyl group, an alkenyl group, an alkoxy group, anaryl group, or a -CHR6-CH2CH=C(CH3)2 group; R2 represents hydrogen or the like; R1 and R2 may bond to each other to form a benzene ring; R3 represents hydrogen or the like; R4 represents hydrogen orthe like; R5 represents hydrogen or the like; and R6 represents hydrogen, a hydroxyl group, or a group including an ester bond).

Description

technical field [0001] The present invention relates to a plant stress tolerance inducer containing a compound having a quinone skeleton as an active ingredient, a method for suppressing rice quality deterioration, a method for easing growth of turfgrass in summer heat, a method for suppressing excessive growth of seedlings, a method for suppressing poor growth of flowers, and quality of fruit trees A method for suppressing deterioration and a method for suppressing quality deterioration of vegetables. Background technique [0002] It is generally known that when plants are exposed to various environmental stresses, they will exhibit stress defense responses, such as expressing stress response genes and the like. However, in recent years, due to the rapid deterioration of the environment and heat stress such as global warming, poor growth of plants, especially a reduction in the productivity of crops has become an international problem. In Japan in recent years, there have ...
