Brassinolide CAS 72962-43-7

what is Brassinolide ?

Brassinolide is a new type of endogenous steroid hormone in plants that can significantly increase plant nutrient growth and promote fertilization at very low concentrations. Brassinolide is internationally recognized as the most active, efficient, broad-spectrum, and non-toxic plant growth regulator. It has a dual effect of causing plant cell division and elongation, promoting root development, enhancing photosynthesis, increasing crop chlorophyll content, promoting effective absorption of fertilizers by crops, assisting the growth of disadvantaged parts of crops, promoting strong roots and seedlings, and preserving flowers and fruits; Improve the cold resistance, drought resistance, salt alkali resistance and other stress resistance of crops, significantly reducing the occurrence of diseases; And it can significantly alleviate the occurrence of drug damage. After the occurrence of drug damage, its use can detoxify, quickly restore crop growth, and eliminate disease spots; Brassinolide can significantly increase yield and improve crop quality.

what is the history of Brassinolide?

 

Brassinolide is a steroid plant hormone. In the early 1980s, brassinolide was first extracted and refined from rapeseed pollen. Due to its ability to significantly increase plant vegetative growth and promote fertilization at very low concentrations, it has received widespread attention. So far, this type of compound has been isolated and identified from dozens of cultivated objects. The growth and development of plants at various stages are controlled and regulated by their own hormones. Given that the current five major categories of endogenous hormones in plants are insufficient to explain the entire process of plant growth and development, it is widely believed that brassinolide is a new type of plant hormone. In addition, the chemical structure of brassinolide is extremely similar to animal sex hormones, therefore, its role in plant reproductive physiology has attracted increasing interest. On the basis of the above work, it was found that Epibrassinolide has a higher effect on crop yield than other natural brassinolides. Currently, the chemical replica of Epibrassinolide is used in agricultural production.If you need it, pls click e-mail sales1@faithfulbio.com

what is the Mechanism of action of Brassinolide?

Brassinolide (BR) is a steroid compound with high physiological activity that promotes plant growth. The discovery of brassinolide and its extremely high physiological activity can be considered a new milestone in the research of plant growth regulators. After years of research, scientists have discovered that brassinolide compounds are a class of natural steroid compounds widely present in many plant bodies. Brassinolide compounds have been found in various organs of plants, such as flowers (pollen), seeds, roots, and leaves. Currently, 18 compounds of this type have been discovered. The treatment concentration of brassinolide is extremely low, generally ranging from 10-1 to 10-5 (mg/L), indicating strong physiological activity. Its main characteristics are: promoting crop growth and increasing nutrient yield; Improve fruit setting rate and promote fruit enlargement; Improve seed setting rate and increase thousand grain weight; Improve crop cold tolerance, reduce pesticide damage, and increase disease resistance..

How to use Brassinolide?

Corn: The top of the corn ear experiences grain failure (i.e. baldness), which is an important factor affecting yield improvement. The whole plant spray treatment with 0.01% brassinolide emulsifiable concentrates 5ml and 50L0.01mg/L water brassinolide can significantly reduce the abortion rate of corn ear top grains and increase the yield by about 20%. The effect of pre-treatment before tasseling is better than that of spraying after silking. The frequency of spraying corn ears increases, although it can reduce the abortion rate, the effect is not as good as spraying the whole plant. The processed corn plants have darker leaf color, thicker leaves, increased dry leaf weight and chlorophyll content, and an enhanced rate of photosynthesis. The activity of the grains at the top of the ear is enhanced (i.e. the relative conductivity decreases). In addition, post-treatment of silk production also has the effect of increasing thousand grain weight. A study conducted a BR yield increase experiment, and the results showed that treating wheat with 0.01mg/L brassinolide can increase the grain setting rate and thousand grain weight of wheat ears, thereby increasing wheat by 10%. Treating corn ears with the same concentration can increase corn yield by 9.8% to 18.4%.

Wheat: After treatment with brassinolide, there is a significant increase in yield. 0.05-0.5mg/L brassinolide has a significant promoting effect on wheat roots (including root length and number) and plant height after soaking for 24 hours. At tillering stage, the effect of leaf spray treatment with this concentration was obvious. Two weeks after treatment, the chlorophyll content of the flag leaves was higher than the control, and the number of grains per ear, ear weight, and thousand grain weight all increased significantly, generally increasing yield by 7% to 15%. The ability of wheat seedlings to tolerate low temperatures in winter is enhanced after treatment with brassinolide. In addition, the lower functional leaves of the plant grow well, increasing the stress resistance of wheat and reducing the chances of infection by diseases such as bacterial wilt.
