Physical and Chemical Properties

White crystal, Melting point: 225-258; The solubility in water is 5mg/L, can dissolve in methanol, ethanol, THF and acetone etc.

Function and characteristic

Brassinolide can increase the activity of RNA polymerase and content of RNA, DNA; Increase the activity of membrane potential and ATP enzyme; Strengthen auxin effect.

1Promote the growth of root system and seedings: If brassinolide used to deal with seeds, it can increase enzyme activity, then promote seeds activity. So it has obvious promotion to root system (length and number of root) and crop height.

2Promote vegetative growth: Brassinolide has the double action to promote cell division and expansion. It can increase the chlorophyll content and enhance plants photosynthesis.

3Promote reproductive growth: Brassinolide can increase fruit bearing rate and fructiferous rate by promoting the germination and elongation of pollen tube, benefiting to crop fertilization. It can also regulate the distribution of photosynthetic products, promote the synthesis of protein and content of sugar, then improving crop quality.

4Increase crop resilience: At low temperature, drought and salinity conditions, brassinolide can increase plant resistance to adverse environment by enhancing water absorption ability of plants, stabilizing the structure and function of membrane system, sustaining higher metabolism, regulating physiological environment in cell, promoting normal physiological and biochemical metabolism.

Application

The dosage of brassinolide is very low, and it can be made SP, AS etc.

Brassinolide can used foliage spraydrip irrigation or with water soluble fertilizer. Recommend dosage: foliage spray 0.01-0.1 mg/L; drip irrigation 0.01-0.05 gram (a.i)/667m2; With water soluble fertilizer 0.05-0.5 g (a.i)/ 667m2.
