Role and Benefits: 
Gibberellic acid is a broad spectrum of low toxicity plant growth regulator, is one of the ubiquitous endogenous hormones in plants five plants.



a. Promote stem elongation growth 
Gibberellic acid the most significant physiological effect is to promote the growth of plants, mainly it can promote cell elongation..Gibberellic acid deal whole plants growth,it significantly promote the growth of plant stems, especially varieties of dwarf mutant effect is particularly evident. For step growth, gibberellic acid mainly promote some internodes elongation become longer, rather than increased the number of sections. 

b. Induce flowering

c. Break dormancy

d. Promote male differentiation

e. Other physiological effects 
Gibberellic acid can also strengthen the effect of IAA on nutrient mobilization and promoting certain plants and fruit parthenocarpy, delay leaf senescence. In addition, gibberellic acid also can promote cell division and differentiation, gibberellic acid to promote cell division is due to the shortening of the G1 and S phase. But gibberellic acid inhibited the formation of adventitious roots but which auxin are different.
