The role of brassinolide
1. Promote root at seedling stage
Used as seed treatment or spraying at seedbed stage, it has obvious growth-promoting effect on seedling roots of rice, wheat, corn, broad bean, tobacco, vegetables and other crops.
Compared with the control, the fresh weight of the root system increased by 20%-50%, and the dry weight increased by 15%-107%.
2. Promoting the nutritional period
Brassinolide has the dual effects of promoting cell division and cell elongation, and can also increase the content of chlorophyll in leaves, enhance photosynthesis, and increase the accumulation of photosynthetic products, so it has a significant effect on promoting plant vegetative growth and can improve crop yield.
3. Reproductive period promotion
Brassinolide can improve the germination rate of pollen, promote the elongation of pollen tubes, and is beneficial to the fertilization of plants, thereby improving the rate of seed setting and fruit setting. In the mature stage of crops, the number of grains and grain weight increased, and the fruits of melons and fruits were uniform, which improved the quality of crops.
4. Enhance resistance to stress
After the brassinolide enters the plant, it not only strengthens the photosynthesis, promotes the growth and development, but also stimulates some protective enzyme activities in the plant, which can greatly reduce the harmful substances (such as Malondialdehyde, etc.) damage to normal function.
A large number of experimental studies and field experiments have proved that brassinolide can indeed enhance the stress resistance of crops, especially in the aspects of drought resistance and low temperature resistance, the effect is more obvious.
5. Alleviate drug damage
When herbicides, fungicides and insecticides are used incorrectly, or the concentration ratio is not appropriate, phytotoxicity is prone to occur. Timely use of brassinolide + high-quality foliar fertilizer can adjust nutrient delivery, supplement nutrition, reduce damage, and accelerate crop recovery.
Note: When dealing with phytotoxicity, pay attention to the use concentration of brassinolide. Too high concentration may aggravate phytotoxicity.
