auxin is specific for root growth. Gibberellic acid is an elongation factor that causes longer stems. It's not that GA doesn't affect roots at all, it's just auxin is the hormone known to promote root growth. Auxin especially affects the determination of a cell to form either a stem or root, and is commercially used to promote root growth. Gibberellic acid is known to effect cell elongation and will cause a plant to grow more leaves and longer stems.

Auxins sell root initiation. Auxin induces the two develop of pre-cutting-edge roots and adventitious root formation, i.e., branching of the roots. As greater close by auxin is transported down the stem to the roots, the final progression of the roots is inspired. If the source of auxin is got rid of, working example the suggestions of stems are trimmed, the roots are much less inspired to that end, and develop of stem is supported instead.
