1. Physiological effect of Brassinolide
Brassinolide is the active plant growth hormone of high efficiency, broad spectrum and non-toxicity. The plant physiologist thought as follows:
Fully stimulate the potency in plants; promoting cell elongation and division in plants; enhance photosynthesis; resist the damage of low temperature, increase crop yield (using brassinolide at the flowering period can increase the yield of corn, wheat, tomato, cucumber and eggplant)
Improve resistance( brassinolide has obvious cold resistance, drought resisting and salt resistance, especially in bad natural conditions, the alleviator of adverse situation)disease resistant (brassinolide can improve the resistance of disease, but useless to rice blast and powdery mildew of cucumber)
Meanwhile brassinolide can alleviate the disease of herbicide for crop and reduce the pesticide residue in crops.

Application 

Brassinolide is a steroidal plant growth regulator. Its function includes:

Promote the growth of plant to increase yield

Raise the ratio of fruit bearing and increase the unit weight.

Enhance the resistance of the plant to drought and cold weather

Enhance the immunity of the plant. Used in tissue culture, regulate thedifferentiation of the tissue.

Packing 1 kg net aluminium bag.
