Brassinolide is a steroidal plant growth regulator.
Brassinolide's function includes:
1. Promote the growth of plant to increase yield.
2. Raise the ratio of fruit bearing and increase the unit weight.
3. Enhance the resistance of the plant to drought and cold weather.
4. Enhance the immunity of the plant. Used in tissue culture, regulate the differentiation of the tissue.
