The Brassinolide is one of the high bioactivity in steroid compounds, and they are widely found in plants. In all stages of plant growth and development, it can not only promote the growth of nutrition, but also facilitate the fertilization effect. Synthetic Brassica lactone activity is high, can be absorbed through the leaves, stems, roots of plants, and then transmitted to the role of the site, some think it can increase the activity of RNA polymerase, increase RNA, DNA content, some think it can increase the cell membrane potential difference, ATP enzyme activity, some think it can strengthen the role of auxin, There is no unified view of the mechanism of action. It works in very small concentrations, is an efficient plant growth regulator, at very low concentrations, that can significantly increase the growth of plant nutrients and promote fertilization.
Brassinolide is a new type of green environmental protection plant growth regulator, which can promote the growth of vegetables, melons, fruits and other crops through suitable concentration soaking and stem and leaf spraying treatment, can improve crop quality, improve crop yield, make the crop color.

3. Increase the chlorophyll content and promote plant's photosynthesis,

4. Strengthen the plant's drought-resistant ability.

5. Brassinolide can improve plants growth and increase output remarkable.
