GA3 is widely used as a plant growth regulator in agriculture, forestry and horticulture. GA3 can promote fruit formation and growth of vegetative organs, break seed dormancy, increase germination, delay aging, and regulate blossoming. In addition, GA3 can change the ratio of male to female flowers; produce parthenogenetic propagation’s accelerate stem elongation; enlarge leaf surfaces; promote the growth of young twigs; and inhibit ripening.

| Advantages︰ | 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. |
