Brassinolide, a omnipotent plant hormone which has big influence on agriculture


Brassinolide is a plant hormone. The first isolated brassinosteroid, it was discovered when it was shown that pollen from rapeseed (Brassica napus) could promote stem elongation and cell division.The biologically active component was isolated and named brassinolide.
24-Epibrassinolide is a type of brassinosteroid, a plant hormone.It is sold commercially in a white powder form for use in plant culture. 24-Epibrassionlide has been shown to improve plant functions in salt- and nickel-stressed environments, as well as increasing enzyme activity.

 28-homo-brassinolide is a plant hormone from a class of polyhydroxysteroids that has been shown to have a protective role in plants under various stress situations; showing significant improvement of plant growth, water uptake, photosynthesis and yield. 28-homo-brassinolide has been shown to be the most effective of any of the brassinosteroids in mitigating plant stress effects from natural conditions such as chilling, drought, heat or salinity.
Brassinosteriods are a group of plant hormones that occur naturally in the plant kingdom. They have a variety of physiological roles including cell division and elongation, gene regulation, photosynthesis, senescence, enzyme activation and growth.


Uses & Benefits:
1)Promote root and seedling growth,enhance seed germination.
2)Promote plant growth, enhance stress resistance.
3)Enhance plant resistance.
4)Increase crop yield.

The role of gamma-aminobutyric acid in agriculture

图片
  γ-aminobutyric acid (CAS number: 56-12-2), (GABA for short), with a relative molecular weight of 103.1, is a four-carbon, non-protein amino acid, which is widely used in vertebrates, plants and Widespread in microorganisms. The content of GABA in plant tissues is extremely low, usually between 0.3 and 32.5 μmol/g.  It has been reported in the literature that the enrichment of GABA in plants is related to the stress response experienced by the plant. When subjected to stress such as hypoxia, heat shock, cold shock, mechanical damage, and salt stress, it will lead to the rapid accumulation of GABA.  It has become a research hotspot to process plant food raw materials into GABA-rich functional products after a certain stress treatment or through microbial fermentation to increase the GABA content in the body.  As a novel functional factor, GABA has been widely used in the food industry.  Foods developed using raw materials such as GABA-rich  germinated brown rice  , soybeans and broad

Analysis on the role of rhizobia in soybean planting

图片
Rhizobium soybean is a live microbial preparation. The rhizobia in the root nodules and the legumes are mutually beneficial: the organic matter produced by the legumes through photosynthesis is partly supplied to the rhizobia; the ammonia produced by the rhizobia through biological nitrogen fixation is supplied to the legumes plant. , it fixes free nitrogen in the air to supply soybeans to meet soybean demand for nitrogen. It is a good measure to increase soybean yield, save fertilizer and reduce pollution, and has been valued by researchers around the world. First, the role of rhizobia 1. Nitrogen fixation Soybean rhizobia uses the products of soybean photosynthesis as energy, and converts nitrogen in the air into nutrients required for soybean growth and development. Rhizobium and soybean have a symbiotic nitrogen fixation relationship. At the beginning, soybean rhizobia fixed little nitrogen, until flowering to drum. The initial stage of grain is the peak of nitrogen fixation by so

The new cotton shoot-controlling product--prohexadione calcium, which is better than uniconazole, does not cause premature aging!

图片
Uniconazole is a triazole plant growth regulator widely used in cotton production. In recent years, it has an obvious effect on controlling the growth of cotton, promoting flowers and peaches, and can also increase the ratio of cotton double bolls. Welcomed by some cotton farmers.  Today, I will introduce to you a new type of plant growth regualtor, which is more effective than Uniconazole. It is better than Uniconazole because it is not prone to premature aging and defertilization of cotton. 1. What is prohexadione calcium Prohexadione calcium is a new type of plant growth regulator developed by Japan Combina Chemical Industry Co., Ltd. It interferes with the synthesis of gibberellic acid in plants, reduces the content of gibberellic acid in plants, controls leggy growth, promotes flowering and fruiting, and increases yield. Make its root system developed, protect cell membrane and organelle membrane, and improve crop resistance ability. So as to inhibit the upper vegetative growth of
