本研究以“金优2号”板栗果实为材料,研究了外源一氧化氮供体硝普钠(SNP)浸果处理对板栗果实采后贮藏性的影响。结果表明,SNP处理可维持板栗果实贮藏期较高的好果率,其中SNP 0.4mmol/L处理贮藏效果最佳,冷藏180d时好果率为81.11%,显著高于对照(56.67%),且延缓了果实淀粉含量的下降,贮藏期间保持了较高的可溶性总糖、还原糖和维生素C含量,对蛋白质含量和含水量影响不大。
In this study, the effects of exogenous nitric oxide donor sodium nitroprusside (SNP) immersion on the postharvest storage of chestnut fruit were studied using chestnut fruit of “Jinyou No.2”. The results showed that SNP treatment could maintain a good fruit yield during chestnut fruit storage, of which SNP 0.4mmol / L treatment had the best storage efficiency, the fruit yield was 81.11% after 180 days of cold storage, significantly higher than that of control (56.67%) Delayed the decrease of starch content in fruit and maintained high soluble total sugar, reducing sugar and vitamin C content during storage, but had little effect on protein content and water content.
