Function Characteristics

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.

1,Promote 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.

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

3,Promote 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 photosyntheticproducts, promote the synthesis of protein and content of sugar, then improving crop quality.

4,Increase 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 physiologicalenvironmentin cell, promoting normal physiologicaland biochemical metabolism.

Application

The dosage of brassinolide is very low, and it can be made SP, AS, EC etc. Common dosage: 0.01%,0.1%SP, 0.01% EC, 0.01%,0.1% AS.

Brassinolide can used foliagespray,dripirrigationor with Water flush fertilizer. Recommend dosage:foliagespray0.01-0.1 mg/L; Dripirrigation0.01-0.05 g (a.i)/mu; With water soluble fertilizer 0.05-0.5 g (a.i)/mu.
