Effects of Postharvest Treatments on Storability of Actinidia arguta Kiwifruit

摘要

Actinidia arguta is a typical respiratory climactic fruit and has low storability and transport-ability under normal conditions. In order to prolong the storage period of A. arguta and reduce the loss, the effects of different postharvest treatments (CaCh, CIO2, I-MCP) on the fruit decay rate, flesh firmness, respiration and storage quality of A. arguta were investigated. The results showed that different postharvest treatments have different effects. Comparative study on the effect of different postharvest treatments on the fruit storability and quality of A. arguta, 1 mmol/L salicylic acid and 1 uL/L 1-MCP could prolong the fruit storage period, the best treatment was 1 uL/L 1-MCP application. 1-MCP treatment could reduce the fruit decay rate, restrain the decline of flesh firmness, and decrease the respiratory peak value, it also could restrain the increase of sugar and soluble solids content, and the decline of Vitamin C content, but had no significant effect on the decline of titratable acidity.
