Abstract:

Natural brassin belongs to the endogenous bioactive substances of steroidal plant, with sterols as the backbone. Brassinolide has the strongest biological activity in natural brassin, which is known as the sixth group of plant hormones, and it is highly effective, broad-spectrum and non-toxic plant growth regulators (PGR). In order to promote the application of brassinolide in agricultural production, this paper reviewed the biological activity and the application of brassinolide in crops, such as grain, fruits and vegetables. The research situation and progress of brassinolide were concluded, including improving seed vigor, promoting crop growth, increasing the yield and quality, improving crops resistance, and mitigating the impact of pesticides on crops. The study points out that the application of brassinolide is the key way to increase crop production and income. At the same time, it could reduce the usage amount of fertilizers and pesticides, decrease crop planting cost and environmental pollution, and will bring significant economic benefits.

Key words: PGR, brassinolide, increasing both production and income, stress resistance, reducing pesticide injury
