A substituted fluorine-containing β-indolebutyric acid compound represented by the formula:
where in Y stands for one member selected from the group consisting of hydroxyl group, alkoxy group, amino group, and alkylamino group, at least one of R¹ and R² stands for one member selected from the group consisting of halogen atom, alkyl group, alkoxy group, aryl group, nitro group, amino group, and alkylamino group, and the remaining one, if any, for a hydrogen atom, a plant growth regulating agent having as a substantial main component thereof the substituted fluorine-containing β-indolebutyric acid compound, and a method for regulating the length of roots sprouting from plant seeds and the length of hypocotyls by causing adhesion of the substituted fluorine-containing β-indolebutyric acid compound to the plant seeds.
