Factory Supply Gibberellin Gibberellic Acid 4 Ec Ga3 4%Ec 77-06-5

Short Description:

GA3 is a broad spectrum plant growth regulator. Endogenous gibberellin is ubiquitous in plants, which is one of the important hormones to promote plant growth and development, and is the antagonist of such growth inhibitors as paclobutrazol and chlormequat. The drug can promote cells, stem elongation, leaf expansion, parthenocarpy, fruit growth, break seed dormancy, change the ratio of female and male flowers, affect flowering time, and reduce the shedding of flowers and fruits. Exogenous gibberellin enters the plant and has the same physiological function as endogenous gibberellin. Gibberellin enters the plant mainly through leaves, twigs, flowers, seeds or fruits, and then transmits to the parts with active growth to play a role.

Mode of Action

GA3 is a broad-spectrum plant growth regulator, which can promote the growth and development of crops, make them mature earlier, increase yield and improve quality; It can quickly break the dormancy of seed, tuber, bulb and other organs and promote germination; Reduce the shedding of buds, flowers, bolls and fruits, improve the fruit bearing rate or form seedless fruits. It can also make some 2-year-old plants bloom in the same year.
