which one would give more roots growth; auxin or gibberellic acid? why? explain me please?

Answer 1

Auxi will give more growth as they are root harmone, For shoots the growth harmone is cytokinin and gibberellic acid is a general growth harmone.

Answer 2

Auxins sell root initiation. Auxin induces the two improve of pre-present roots and adventitious root formation, i.e., branching of the roots. As extra interior sight auxin is transported down the stem to the roots, the first progression of the roots is inspired. If the source of auxin is bumped off, working example the preparation of stems are trimmed, the roots are much less inspired for that reason, and improve of stem is supported instead.
