Physiology and Application of Gibberellins in Postharvest Horticultural Crops

Gibberellins (GAs) are plant hormones indispensable in regulating the growth and development of fruits. Recent studies have shown that GAs play important roles delaying horticultural crop ripening senescence, enhancing internal external quality crops resistance to stress disease. We reviewed role postharvest physiology fruits recent years. closely related their ability retard fruit senescence. could effectively improve storage significantly increase flesh hardness, reduce respiration intensity, inhibit release endogenous ethylene, softening ripening. It can also intrinsic extrinsic by improving shape, color, reduction soluble solids, promoting sugar accumulation, vitamin loss. a biotic abiotic resistance. The GA treatment reduces cold damage index, production accumulation superoxide anion(O2−), improves antioxidant capacity fruits, maintains integrity cell membranes during low-temperature storage. Moreover, control some diseases. In conclusion, an physiological regulation application prospects
