Plant growth enhancing compositions using gibberellins, indoleacetic acid and kinetin

摘要

A plant growth enhancing composition comprising as an active ingredient a synergistic mixture of (a) gibberellins, (b) the heteroauxin indole-3-acetic acid and the cytokinin 6-(4-hydroxy-3-methyl-2-trans-betenylamino) purine in definite proportions. Application of the composition to the locus of various plants or to the seeds of a plant produces a wide variety of plant growth enhancing responses including, increasing yields; stimulating seed germination and breaking of dormancy; increasing flowering and fruiting; preventing lodging and freeze injury; aiding in the recovery of damaged crops and increasing root proliferation.
