[Product Introduction]

Chitosan oligosaccharide (COS) can inhibit bacteria, induce chitinase production in plant cells and tissues, increase enzyme activity, promote protein synthesis, regulate gene closure and opening, and induce IAA synthesis. Stimulate a variety of plant growth and development genes, synthesize bioactive substances conducive to plant growth, activate plant cells, and promote the rapid growth and development of plants.

the results showed that chitosan oligosaccharide could promote uniform emergence, thick main stem, early ridge closure, early growth of plants, shorten the time of vegetative growth, flowering 2-3 days ahead of time, lay the foundation for yield increase, and harvest 3-5 days ahead of the blank control. the results showed that low concentration of chitosan oligosaccharide (the optimal concentration was 0.1mg L-1) could promote the growth of cucumber seedlings. Compared with the control group, the growth indexes were significantly increased growth of rice seedling.
