Detailed explanation-1: -Auxin and cytokinin are critical growth hormones in plant development and are naturally present within the plant at variable concentrations throughout the season.
Detailed explanation-2: -Fruit growth is mainly dependent on auxin and cytokinin.
Detailed explanation-3: -Cytokinin is known as the hormone responsible for cell division. It stimulates the metabolism and the formation of flowers on side shoots, and as such it is a counterpart to auxin. Cytokinin is most concentrated in the youngest parts of the plant, such as the seeds, fruits, young leaves and root tips.
Detailed explanation-4: -Cytokinin, which triggers cell division, was first discovered more than 50 years ago. This plant hormone controls every aspect of plant growth and development, including meristem function, vascular development, stress responses, and senescence.
