Abstract: Effects of exogenous sodium nitroprusside (SNP), a nitric oxide (NO) donor, on browning and decay of postharvest longan (Dimocarpus longan Lour. cv. Shixia) were investigated. Application of 0.5mmol/L and 1mmol/L SNP could significantly delay the skin browning during storage. NO inhibited POD activity may account for browning inhibition. NO also markedly reduces decay development and pulp breakdown. Futhermore, SNP treatment can result in higher level of total soluble solids and ascorbic acid than control fruits, but can not affect total soluble solids

Key words: nitric oxide, longan, postharvest, browning, decay
