PURPOSE:The titled regulator to control effectively germination of side buds of tobacco without exerting a bad influence on growth and yield of tobacco, having inhibitory action on buds of woody plants, comprising an N-substituted alanine derivative and an inert carrier. CONSTITUTION:A plane growth regulator comprising an N-substituted alanine derivative shown by the formula I (X is halogen, or trifluoromethyl; R is H, 1-8C alkyl, 2-4C alkenyl, metallic atom, or amine forming residue; n is 0, 1, or 2) and an inert carrier. When it is used, an emulsion form is preferable, for example, preferably the regulator is blended with a solvent such as benzene, etc., and various surface active agents, etc., diluted with water into about 1,000-5,000ppm concentratoin and used. The compound shown by the formula I, for example, is obtained by reacting a compound shown by the formula II with a compound shown by the formula III (Hal is halogen; R<1> is lower alkyl), to give a corresponding compound shown by the formula I.
