Abstract:

Rubber tree(Hevea brasiliensis) is one of the important tropical cash crops, and natural rubber(NR), a secondary metabolite, is an important industrial raw material and strategic material in China. Phytohormones play important roles in regulating plant growth, development, germination, and environmental responses. Here, the research progress on application of four phytohormones, Ethylene, Abscisic acid, Brassinolides, and Gibberellin in the growth and development of rubber trees, NR biosynthesis, rubber yield, latex flow, and quality formation, was summarized in detail, and the application prospect of four phytohormones in mechanism research of improving rubber production and latex flow was looked forward to provide theoretical support for the rubber industry development.

Key words: Hevea brasiliensis, latex flow, plant hormone, natural rubber, biosynthesis
