It is a broad-spectrum endogenesis plant growth regulator. It can stimulate rooting system of plant's and cuttings' (herbaceous and woody ornamentals), and it can increase various fruits and melons' fruit-setting rate. It can promote cell division and cell growth, increase errant roots and fruitage; to prevent plantsfrom dropping fruit, to change the ratio of male and female flowers;It also can get inside the plant through leaves and cortices to reach the action point with the nutrient flow.
