Preharvest Foliar Sprays of Prohexadione–calcium, a Gibberellinbiosynthesis Inhibitor, Induce Chlorophyll Degradation and Carotenoid Synthesis in Citrus Rinds
Rind color is an important cosmetic preference of consumers when purchasing citrus fruit. As citrus fruit mature, a decrease in chlorophyll concentration unmasks the presence of carotenoid pigments followed by further synthesis of carotenoids, resulting in the first appearance of the characteristic orange color of mandarins and sweet oranges.
