本论文以云南石林县“次郎”甜柿为实验材料，采用1-甲基环丙烯(l-methylcyclopropene，l-MCP)处理，结合纳米袋包装，研究常温贮藏条件下对甜柿贮藏品质和贮藏期的影响。 1 两种不同处理对“次郎”甜柿保鲜效果的研究 以“次郎”甜柿为试验对象，采用单独纳米袋包装和1-MCP结合纳米袋包装两种方式对甜柿进行处理，在常温(20℃)、RH85%~90%条件下贮藏甜柿，通过测定硬度、失重、可溶性固形物、酸、颜色等生理指标，比较不同处理对甜柿贮藏保鲜的影响。 试验结果显示，在贮藏前期，纳米包装能有效的保持柿果果实的硬度和酸含量，但是后期作用不大，而1.0 μL/L 1-MCP结合纳米包装处理能在整个贮藏期内有效的维持柿果的硬度和酸含量；1.0 μL/L 1-MCP结合纳米包装处理能够延缓可溶性固形物的上升，延缓底色的转变，尤其是a*值的上升，对于柿果的外观、品质保持效果显著优于纳米袋包装处理。对于失重率，两种处理方式无显著差异，表明1-MCP对失重的抑制效果不大。 ......

In this article,Jiro persimmon from yunan was treated by 1-MCP combined with nano-packaging.The effect of this treatment on the storage quality of Jrio was evaluated. 1 The research of effections of two different treatment on Jrio Jrio was treated by two ways. One was nano-packaging, and the other was treated by 1-MCP combined with nano-packaging. Then all the persimmon were put in 20℃,RH85%~90% environment for storing. The changes of firmness, loss weight, SSC, TA, fruit color were measured so that we can find out the better treatment. The result shows that the storing quality of Jiro treated by1-MCP combined with nano-packaging was significantly better than Jiro treated by nano-packaging only. It can maintain the firmness ,SSC, TA, color especially a*. Besides, both of the two treatment can preserve the loss of weight. It can be seen that 1-MCP have little effect on preserve the loss of weight. ......
