What is the mechanism of high-growth promoting activity of Natural Brassinolide on plants？
Mar. 9, 2020
Follow
ChinaNatural Brassinolide, with its main active ingredient, 14-Hydroxylated Brassin osteroid (CAS NO.: 457603-63-3), is a class of plant hormone with high-growth promoting activity found in pollen, anthers, seeds, leaves, stems, roots, flowers, grain, and young vegetative tissues throughout the plant kingdom with particularly high pollen contents.
In China, Rape pollen is abundant and cheap. Chengdu Newsun Crop Science Co., Ltd. developed Natural Brassinolide from rape pollen and obtained many by-products, such as various proteins and Polysaccharide (about 60%). Its use in health foods can greatly reduce the production cost of Natural Brassinolide. This approach makes it possible to industrialize the production of Natural Brassinolide.

2. The mechanisms of action of Natural Brassinolide
|
Physiological effects of natural brassinolids on plants
|
|
|
Cell level
|
Whole plant level
|
|
Effect on the protein spectrum and the amino acid composition of proteins.
|
Effect on the content of nutritive components and fruit quality improvement, dry matter increase.
|
|
Increases chlorophyll content and promotes photosynthesis, hence enhancing the carbohydrate biosynthesis in plants and increasing sugar content.
|
Effect on contents of dry matter, carbohydrates, sugar, vitamins. Total dry matter increase.
|
|
Stimulation of elongation and fission.
|
Growth promotion.
|
|
Effect on hormonal balance.
|
Increase in the success of fertilization.
|
|
Effect on enzyme activity; H+ -pump activation.
|
Shortening the period of vegetative growth.
|
|
Activation of protein and nuclear acid synthesis.
|
Size and quantity of fruits will increase.
|
|
Effect on the fatty acid composition and properties of membranes.
|
Increased resistance to unfavorable environmental factors, such as stress and diseases, and enhanced storage of fruits.
|
|
Increased photosynthetic capacity and translocation of products.
|
Quality and yield rise.
|
|
Enhanced activity of SOD in the leaves of plants. More H+ ions released from the leaves, which can minimize osmosis and protect cell membranes.
|
Enhanced defense system and immunity of plants, as well as storage of fruits.
