発明の名称 (英語) AGENT FOR INDUCING OSMOTIC PRESSURE STRESS TOLERANCE IN PLANTS, AND METHOD FOR ALLEVIATING DRYING STRESS NEW
発明の概要(英語) Provided are: an agent for inducing osmotic pressure stress tolerance in plants which exhibits excellent osmotic pressure stress tolerance inducing action on plants; and a method for alleviating drying stress. This agent for inducing osmotic pressure stress tolerance in plants includes, as an active ingredient, a compound having a quinone 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, an aryl 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 or the like; R5 represents hydrogen or the like; and R6 represents hydrogen, a hydroxyl group, or a group including an ester bond).
従来技術、競合技術の概要(英語) BACKGROUND ART
In general, a plant, when exposed to various environmental stresses, stress protective response, for example stress response genes known to be expressed and the like.However, in recent years rapid environmental degradation, such as global warming heat for example, by drought stress, poor growth of the plants, in particular international reduction in productivity of the crop in question.In Japan in recent years, a period of intense heat in the summer, by drying or heat as claimed in claim, damage to the occurrence of many instances.For example, the grass, dry air and the heat due to the intense heat of the immature white grain rice or the like and the problem of occurrence of particles.
Conventionally, such a, measures against the plant stress, various studies have been superimposed.For example, by growing agricultural materials such as a house, a method of controlling the growth environment is known.However, a large-scale construction is required and a wide range, high costs are required for the problem.In addition, by cross breeding techniques, the method according to the production of the plant stress resistance, in order to enhance the stress resistance of the plant itself fundamentally has attracted attention as a method.However, it takes time and trouble for mating, the rapid environmental degradation in the efficiency corresponding to the shape of a target plant to produce a problem that it is not possible.
Therefore, at present, and stress resistance of the stress of a plant using an inducing agent resistance induction method has been sought.As the stress-induced resistance, for example such as disclosed in Patent Document 1, studies about natural components have been switched to.Patent Document 1 is, yeast cell wall including enzymatic degradation to environmental stress tolerance of a medicament for the disclosed composition.
