PURPOSE:The titled composition, containing a specific brassinolide based plant hormone and choline salt as active constituents and capable of activating plant hormones, promoting nutrient translocation, embryogenesis, etc., and exhibiting yield increasing effect on cultivated plants. CONSTITUTION:A yield increasing agent composition containing one or two or more 27C, 28C and 29C brassinolide based plant hormones, e.g. 2alpha,3alpha,22R,23R- tetrahydroxy-24S-methyl-B-homo-7-oxo-5alpha-cholestan-6-one, and one or two or more of choline salts as active constituents and formulated into the dosage form of powder, aqueous solution, etc., in use. The concentration thereof in using as a solution, 0.0001-3ppm, preferably 0.001-1ppm brassinolide based hormones and 5-3,000ppm, preferably 20-2,000ppm choline salts. The mixing ratio of the former to the choline salts is preferably 1:1,000-1:1,000,000. |
