Detailed explanation-1: -The Plant Hormone Gibberellin By producing large quantities of GA, the plants become long and slender, are incapable of supporting their own weight, and are chlorotic and partially infertile [1].

Detailed explanation-2: -Gibberellins are tetracyclic diterpenoid hormones that stimulate aspects of plant development, such as root and shoot elongation, seed germination, flower transition, and fruit set and expansion (1). They stimulate these processes by disrupting proteins from the DELLA family of negative regulators (2, 3).

Detailed explanation-3: -Gibberellic acid increases fruit firmness, fruit size, and delays maturity of ‘sweetheart’ sweet cherry.
