Brassinolide is a highly potent plant growth regulator and is recognized internationally as the most active, broad-spectrum, non-toxic plant growth regulator. At very low concentrations, it can significantly increase the vegetative growth of plants and promote fertilization. Some of its physiological functions are characterized by auxin, gibberellin, and cytokinin. So what is the role of brassinolide? How much is the use of brassinolide?
The role of brassinolide
1. Promote cell division, increase leaves, and promote fruit enlargement;
2. Promote photosynthesis, increase chlorophyll content, and delay leaf senescence;
3. Break the top advantage and promote the germination of side buds;
4. Improve pollen fertilization and increase fruit set rate;
5. Regulate the distribution of nutrients in plants and improve the synthesis of nutrients such as protein and sugar;
6. Promote the development and growth of vulnerable organs;
7. Improve plant physiological metabolism;
8. Break the dormancy and promote seed germination;
9. Enhance disease resistance and stress resistance, and reduce the harm of unfavorable environment (temperature, disease, pesticide , salt and drought);
10. There is a role in balancing other plant hormones.
The efficacy of brassinolide
Due to the addition of efficient and safe imported auxiliaries, it has strong penetrability and fast internal absorption; it effectively increases chlorophyll content, improves photosynthesis efficiency, promotes roots and strong seedlings, preserves flowers and preserves fruit; improves crop cold resistance, drought resistance, salt and alkali resistance, etc. Resistant to stress, significantly reduce the occurrence of disease; and can significantly alleviate the occurrence of phytotoxicity, detoxification after the occurrence of phytotoxicity, so that crops can quickly restore growth and eliminate disease spots; brassinolide can significantly increase yield and Improve the quality of crops. Dilution factor at the time of use: 1200-1500 times solution.
The amount of brassinolide
Soybean seed germination and seedling growth can be promoted by soaking seeds with suitable concentration of brassinolide and spraying with stems and leaves. Within the concentration range of 0.01-0.5 mg/L, solanin lactone soaking can promote soybean germination; At 0.5 mg/L, hypocotyl rupture is easy to occur. Seedling stage 0.1 mg/L stem and leaf treatment can significantly increase the accumulation of fresh weight, root fresh weight and dry matter of soybean, and the growth of bean seedlings is strong. The effect of fresh weight increase of tea treated with 0.02mg/kg was more significant. Brassinolide can be sprayed on the surface of the leaves, or soaked or seeded. The desired effect can be achieved with a concentration of 2500-5000 times.
