Auxin is a hormone present in plants, that promotes or inhibits their growth. It may also be synthesized, especially to obtain naphthalene acetic acid. The effects of auxin differ according to the part of the plant, even with an identical concentration. It can develop the stem of the plant while slowing the growth of buds. A strong concentration of auxin promotes the growth of roots and cuttings, but only for a short period of time.
