As a plant growth regulator, Brassinolide has received widespread attention and love from farmers. There are 5 different types of Brassinolide commonly found on the market, which have common characteristics but also some differences. Because different types of Brassinolide have different effects on plant growth. This article will introduce the specific situation of these 5 types of Brassinolide and focus on analyzing their differences.


Common characteristics of Brassinolide
The common characteristics of Brassinolide are that it contains Brassinolide, a bioactive substance and steroidal compounds. They can work at low concentrations and have the following effects: promote crop growth and increase yield in the vegetative body, increase fruit setting rate and fruit hypertrophy, increase thousand-grain weight, increase yield and quality, enhance crop cold resistance, reduce fertilizer and drug damage and increase disease resistance, and promote cell division and reproductive growth. These effects are the main reasons why farmers like to use Brassinolide.

However, there are two major differences between these 5 types of Brassinolide, namely the source and activity level.

Different sources
1.14-Hydroxylated brassinolide: This is a natural substance that comes from organisms in nature, especially rapeseed. It is extracted from plants by scientific methods and is an organic and biologically active sterol substance.
2.28-homobrassinolide, 28-epihomobrassinolide, 24-epibrassinolide and 22,23,24-trisepibrassinolide: These species are sterol substances obtained by chemical synthesis. Unlike 14-Hydroxylated brassinolide, their source is a chemically synthesized substance, which is one of the important differences between them and14-Hydroxylated brassinolide.

Different degrees of activity
The biological activity of various types of brassinolide mainly depends on the activity and content of the steroidal alcohols themselves. When evaluating the biological activity of different types of brassinolide, 14-Hydroxylated brassinolide is usually used as a reference.
14-Hydroxylated brassinolide>28-homobrassinolide>28-epihomobrassinolide>24-epibrassinolide >22,23,24-trisepibrassinolide


Among the brassinolides synthesized, 28-homobrassinolide has the highest biological activity and contains the highest content of steroidal compounds. In the specific use process, its effect is second only to 14-Hydroxylated brassinolide, and it is the best one among the four types of compound brassinolide. In contrast, 22,23,24-trisepibrassinolide has the least sterols and the lowest biological activity. However, it is very important to choose the right brassinolide type according to the needs to give full play to its role, avoid wasting this precious resource, and save the cost of use.

Summary
There are many types of brassinolide on the market, including 14-Hydroxylated brassinolide, 28-homobrassinolide, 28-epihomobrassinolide, 24-epibrassinolide and 22,23,24-trisepibrassinolide. These types of brassinolide contain biologically active substances and have the effect of promoting plant growth.

The difference is mainly reflected in the two aspects of source and activity. 14-Hydroxylated brassinolide is a natural substance, while the other types are chemically synthesized. In terms of biological activity, 28-homobrassinolide has the best effect, while 22,23,24-trisepibrassinolide has a poor effect.

For farmers, it is very important to choose the right type of brassinolide. They need to make choices based on the needs of the crops and the expected effects in order to give full play to the role of brassinolide and improve the yield and quality of the crops.
