alpha-Ketol unsaturated fatty acid derivative and plant growth regulating agent using same

摘要

alpha-Ketol unsaturated fatty acid derivatives represented by the general formula (1); and plant growth regulators containing the same, which develop plant growth regulation performance such as flower bud formation acceleration in low concentrations and are excellent in stability: wherein R1 is straight-chain C1-5 alkyl or a straight-chain unsaturated C3-5 hydrocarbon group having one or two double bonds; and R2 is straight-chain C1-15 alkylene or a straight-chain unsaturated C2-15 hydrocarbon chain having one to three double bonds, with the proviso that the number of carbon-carbon double bonds is at most four.
