Detailed explanation-1: -Cytokinins promote cell division and increase cell expansion during the proliferation and expansion stages of leaf cell development, respectively. During leaf senescence, cytokinins reduce sugar accumulation, increase chlorophyll synthesis, and prolong the leaf photosynthetic period.
Detailed explanation-2: -Cytokinins are a group of plant growth regulators which are primarily involved in performing cell division in plant roots, shoot system. This hormone helps in promoting the cell’s growth, development, differentiation, affecting apical dominance and delay in leaf senescence.
Detailed explanation-3: -Cytokinins are essential plant hormones. By stimulating cell division, they regulate shoot meristem size, leaf primordia number, and leaf and shoot growth. They can stimulate both the differentiation and the outgrowth of axillary buds. The cytokinins can mediate axillary bud release from apical dominance.
