| 摘要 |
The present invention relates to a plant growth regulator comprising as an active ingredient an epoxycyclohexane derivative represented by general formula (1): wherein R1 is a hydrogen atom, a C1-C6 alkyl group or C3-C6 cycloalkyl group, and R2 and R3 are independently C1-C6 alkyl groups or are combined to form a C2-C3 polymethylene group which may be substituted with a C1-C6 alkyl group, as well as to a plant growth regulator comprising the epoxycyclohexane derivative and a brassinosteroid as active ingredients. The epoxycyclohexane derivatives exhibit a potent plant growth regulating action which is equivalent to or higher than that of abscisic acid, and are useful as plant growth regulators such as a plant growth accelerator, a germination growth accelerator, a transpiration and wilting inhibitor, a cold resistance enhancer, an accelerator for growing, thickening or maturing fruits, roots, stems or bulbs, etc. A synergistic effect is achieved by combination of the epoxycyclohexane derivative with a brassinosteroid. |
