Gibberellic acid GA3 is a broad -spectrum plant growth regulator. Plants generally have natural endogenic cinotomycin. It is one of the important hormones to promote plant growth and development. It can promote cells and stems, expand the leaves, solidity, grow fruit, break the body sleep, change the ratio of male and female, affect the flowering time, and reduce the flowering of flowers and fruits. It is an antagonist for growth inhibitors such as polyzole and shorthalin. Extension, induced long -day plants under short -day conditions, blooming, break the dormant, promote the physiological effects such as fruits and monomer, and cell division and differentiation. The most significant effect of Gibberellic acid GA3 is to promote tissue growth, increase the height of the plant, and the elongation effect on several genetic dwarf plants is particularly obvious. It can significantly promote the growth of plant stems and leaves, especially for hereditary and physiological dwarf plants to promote growth. It can also replace the light and low temperature conditions required for certain seed germination, thereby promoting germination. It can make long -day plants bloom under short -day conditions and shorten the life cycle.
