EPOXYCYCLOHEXANE DERIVATIVE AND PLANT GROWTH REGULATOR

摘要

A plant growth regulator containing an epoxycyclohexane derivative represented by general formula (1) and another plant growth regulator containing both the epoxycyclohexane derivative and a brassidosteroid as the active ingredient. In said formula, R1 represents hydrogen, C1-C6 alkyl or C3-C6 cycloalkyl; and R2 and R3 either represent each independently C1-C6 alkyl or are combined together to represent C2-C3 polymethylene that may be substituted by C1-C6 alkyl. The above derivative has a potent plant growth regulating effect equivalent or superior to that of abscisic acid and is useful as a plant growth regulator, e.g., plant growth accelerator, germination accelerator, transpiration/wilting inhibitor, cold resistance enhancer, and accelerator for the growth, thickening or ripening of fruits, roots, stems or bulbs. The combination of the derivative with the steroid produces a synergistic effect.
