Physiological function of gibberellin;

1. Promoting maltose conversion (inducing the formation of α -amylase); Promote vegetative growth (not promoting the growth of roots, but significantly promoting the growth of stems and leaves), prevent organ loss, and break dormancy.

Second, the most prominent function is to accelerate the elongation of cells (gibberellin can increase the content of auxin in plants, and auxin can directly regulate the elongation of cells), and it can also promote cell division and cell expansion (but it will not cause acidification of cell walls).

Physiological function of abscisic acid;

1, promoting shedding

Step 2 inhibit growth

Step 3 promote dormancy

4, leading to the closure of pores.

5. Regulate the development of seed embryo.
