As a plant growth endogenous hormone, brassinolide is the most active and functional found so far, there is no doubt that "naturally extracted" has high activity, because chemically synthesized ones have to be transformed in the plant body to stimulate receptors in order to achieve the effect.
However, "naturally extracted" from rapeseed pollen is more expensive, extraction amount is small, and chemically synthesized brassinolide has become mainstream product in the market.
It is not very important which kind of brassinolide is good, the most important thing is which product has a better effect and can bring benefits to growers in increasing yields.
Bright-BR (28-epihomobrassinolide 0.01%) SL
1. Improve crop cold resistance and stress resistance.
Bright-BR has the function of inducing resistance, producing more defensive enzymes, improving immunity, and enhancing stress resistance. It has been proved that the use of Bright-BR has higher crop stress resistance and can reduce frost damage in cold and low temperature environment.
2. Increase crop pollination, plump grain.
Bright-BR can improve plant photosynthetic rate, improve peroxidase and nitrate reductase activities, promote crop carbon and nitrogen metabolism, enhance plant absorption of water and fertilizer and dry matter accumulation, effectively promote crop pollination, accelerate the absorption of crop fertilizer, promoting firmness and fullness of grains.
3. Promote flowering and protect flowers, protect and strengthen fruits.
4. Bright-BR can regulate hormone balance in plants, promote flower bud differentiation, protect flowers and prevent falling fruit.
