Abstract:

Effects of preharvest calcium spray, bag cover, waxing and postponed harvest on peel browning and qualities of “Fengjie” navel orange (Citrus sinensis Osbeck) were investigated during storage. Results indicated that peel browning was significantly reduced by preharvest calcium spray and bag cover during storage (p < 0.01). Besides, this preharvest calcium treatment also improved skin redness of fruit as well as its quality. However, the peel browning of “Fengjie” navel orange was markedly enhanced by postharvest waxing and postponed harvest. The results suggested that calcium deficiency, waxing, and unsuitable collecting time might be important factors inducing peel browning in navel orange fruits.

Key words: navel orange (Citrus sinensis Osbeck), peel browning, controlling, technology
