Title:
PLANT BRANCHING INHIBITOR, METHOD FOR PRODUCING SAME, AND PLANT BRANCHING INHIBITORY COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2010/137662
Kind Code:
A1
Abstract:
A compound which has a plant branching inhibitory activity equal to or higher than that of a strigolactone, can be chemically synthesized inexpensively by a simple process, and has no or a weak promoting effect on the germination of seeds of plants of the genus Striga is developed. A plant branching inhibitor comprising a compound represented by general formula (1) or a salt thereof and a plant branching inhibitory composition comprising the plant branching inhibitor are provided. In general formula (1), R1 and R2 each independently represent a hydrogen atom (H), a lower alkyl group, a lower alkenyl group, or a lower alkynyl group.
