Write three characteristics of the vegetative hormone that plays the main role in the upward growth of vegetation
Answers
Explanation:
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.
Cytokinins were originally defined as chemicals that induce cell proliferation and trigger callus differentiation to shoot when applied with auxins, but now it is known that cytokinins play a key role in many aspects of plant growth and development [3], including embryogenesis, maintenance of root and shoot meristems
Gibberellin. Gibberellins (GAs) are plant hormones that regulate various developmental processes, including stem elongation, germination, dormancy, flowering, flower development, and leaf and fruit senescence. GAs are one of the longest-known classes of plant hormone.
