Document Summary
Types of plant hormones: auxins, stimulates stem elongation, promotes formation of lateral and adventitious roots, regulates development of fruit, differentiation of cells, enhances apical dominance, shoot apical meristems and young leaves are the primary sites of auxin, cytokinins synthesis, found mainly in roots, stimulate cell division in shoots and roots, stimulate germination, promote lateral bud growth, gibberellins, seed, bud, and fruit development, stem elongation and pollen development, fruit growth (both auxin and gibberellins have to be present, sex determination i. Iii: auxin stem elongation, apical meristem produces auxin, transported down the shoot (only, produces a decreasing concentration gradient, high concentrations of auxin inhibit stem elongation, low concentrations of auxin promote stem elongation by activating h+ active transport mechanisms, apical dominance, auxin and cytokinin in apical dominance, auxins are produced by the meristem and transported down the shoot, auxins inhibit lateral shoot development, cytokinins stimulate lateral shoot development, auxins and cytokinins work against each other.
