Does Auxin Promote Cambial Activity?

Cell enlargement, cell division incensement in the cells of vascular cambium, apical dominance and root formation in callus are the characteristic feature of auxins. Degree of cambial activity is directaly proportional to auxin concentration.

What do auxins promote?

Auxins promote stem elongation, inhibit growth of lateral buds (maintains apical dominance). ... Auxin is a plant hormone produced in the stem tip that promotes cell elongation. Auxin moves to the darker side of the plant, causing the cells there to grow larger than corresponding cells on the lighter side of the plant.

Does auxin promote cell growth?

Auxin promotes cell division and meristem maintenance and also plays an important role in the establishment of cellular patterning. Plant development thus integrates the regulation of cell proliferation and growth with further cell expansion and differentiation.
