Brassinolide

Brassinolide is a new type of plant growth regulator, which was first discovered by American agricultural scientists in 1970. Compared with other five growth regulators, Brassinolactone has unidirectional pertinence and is called the sixth class of plant hormones. Today to analyze this component, I hope you can understand, the correct use of brassinolactone.

Brassinolide is not a foliar fertilizer. Foliar fertilizer is a nutrient fertilizer (e.g., phosphorus, potassium, boron, zinc, rare earth elements, amino acids, etc.), which can affect crop growth if lacking.Brassinolide itself has no nutrition. It regulates crop growth indirectly by regulating the endogenous hormone system of plants, and has good compatibility with foliar fertilizer.

The role of brassinolactone

1. Promote the root growth of crops in the seedling stage

Used as seed treatment or seedbed stage spraying, it has obvious growth promoting effect on seedling roots of rice, wheat, corn, broad bean, tobacco, vegetables and other crops.Compared with the control, the fresh weight of root increased by 20%-50%, and the dry weight increased by 15%-107%.

2. Promote growth during the vegetative period

Brassinolide has the dual effect of promoting cell division and cell elongation, but also can increase the content of chlorophyll in leaves, enhance photosynthesis, and increase the accumulation of photocontract products, so it has obvious effect of promoting plant vegetative growth, and can increase crop yield.

3. Promote fruit growth during the reproductive period of crops

Brassinolide can improve the germination rate of pollen, promote the elongation of pollen tube, and facilitate the fertilization of plants, so as to improve the seed setting rate and fruit setting rate. The grain number and grain weight of crops increased in the mature stage, and the fruits of melons and fruits showed uniform fruits, which improved the quality of crops.

4. Increase stress resistance

After entering the plant body, brassinolide not only enhances photosynthesis, promotes growth and development, but also stimulates the activities of some protective enzymes in the plant body, which can greatly reduce the damage to normal function caused by harmful substances (such as malondialdehyde, etc.) produced by the plant body under stress.
