Detailed explanation-1: -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.
Detailed explanation-2: -It is a plant hormone influencing the stimulation and growth of cell division. These are synthesized in the roots and typically are derived from adenine. They are critical in the processes of cell differentiation and normal growth, which takes place in the fruits and leaves.
Detailed explanation-3: -It has been recognized that cytokinins are plant hormones that influence not only numerous aspects of plant growth, development and physiology, including cell division, chloroplast differentiation and delay of senescence but the interaction with other organisms, including pathogens.
