摘要：

为探讨用NO进行芒果保鲜的新方法，以硝普钠（SNP）为NO供体，采用不同浓度的SNP浸泡处理芒果（Mangifera indica L. ‘Tainong No.1’），研究芒果贮藏期间的外在品质和采后生理生化变化。结果表明，10 μmol/L的SNP处理能够有效推迟芒果硬度下降、抑制果实转黄、控制重量损失、提高好果率、降低病害指数、控制可溶性固形物的变化，其货架期延长3~4天。640 μmol/L和1280 μmol/L SNP处理对芒果产生明显的毒害作用，且表现出随浓度的升高毒害加重的趋势。SNP处理能够控制芒果的各种外在和内在指标的变化，但有一定的浓度范围。超过这范围，反而起毒害作用，并且这种毒害作用与浓度成正比。

Abstract:

In order to discuss a new preservation method with NO for Mangifera indica, using sodium nitroprusside (SNP) as a nitric oxide (NO) donor, studied the effects of Mangifera indica L. ‘Tainong No.1’ with different concentrations of SNP treatments, the changes of external quality and postharvest physiology biochemical during storage period. The result showed that, the treatment of 10 μmol/L of SNP can effectively delayed the decrease in hardness, inhibit yellow rate of fruit, control weight loss, increase good fruit rate, lower disease index. The store life could extend by 3~4 days. The treatment of 640 μmol/L and 1280 μmol/L of SNP produced a significant toxicity for Mangifera indica, and demonstrated the trend that increased toxicity with increasing concentration. The SNP treatment could control the variety changes of internal and external indicators of mango, but there was a certain concentration range. Exceed this range, formed the toxic effects and toxic effects had a relationship with this concentration.
