PROBLEM TO BE SOLVED: To provide a method for imparting drying tolerance to a plant easily usable and capable of sufficiently performing the opening of pores in irrigation, and to provide a plant drying tolerance imparting agent used therefor. ! SOLUTION: A method for imparting drying tolerance to a plant includes scattering at least any of a compound represented by formula, its derivative and their salts. In the plant drying tolerance imparting method, preferably, ABA8'-hydroxylase is specifically suppressed to increase the concentration of internally generated abscisic acid. In the plant drying tolerance imparting method, more preferably, the concentration of internally generated abscisic acid is increased without suppressing the growth of a plant. !
