Application | One of the most widely used plant growth regulator in agriculture, forestry and horticulture in China. It has following physiological functions: changing male/female ratio of flowers, inducing monogenetic reproduction, stimulate fruit setting and growing, breaking domance of seeds and accelerating germination, promoting stem elongation, and enlarging leaf surface. It can help accumulation of metabolites in phloem, activate cambium, inhibit prematuration and retard aging. |
