Stimulates stem elongation (low concentration only), root growth, cell differentiation, and branching; regulates development of fruit; enhances apical dominance
|
Auxin
|
|
|
Affect root growh and differentiation; stimulate cell dviision and growth; stimulate germination; delay senescene
|
Cytokinins
|
|
|
Promote seed and bud germination, stem elongation, and leaf growth; stimulate flowering and development of fruit; affect root growth and differentiation
