1‐Methylcyclopropene Containing‐Paper Enhances the Storability of Anxi Persimmon by Regulating Energy Metabolism

ABSTRACT In present work, the impacts of 1‐MCP containing‐paper treatment on the storability of Anxi persimmon fruit and its relationship with energy metabolism were evaluated. The results indicated that, during storage, in comparison to control persimmon, the 1.35 μL L −1 1‐MCP‐treated persimmon displayed higher commercially acceptable fruit rate (CAFR), delayed the change of fruit color, and maintained higher energy charge and ATP content. Additionally, during mid‐late storage, the 1‐MCP‐treated samples showed the enhanced activities of H + ‐ATPase, Ca 2+ ‐ATPase, and Mg 2+ ‐ATPase on the membranes of plasma, vacuole, and mitochondrion. These outcomes revealed that 1‐MCP containing‐paper delayed the color change and maintained higher CAFR in postharvest Anxi persimmon fruit were attributed to the increased ATPases activities and higher energy level. Therefore, 1‐MCP containing‐paper treatment can enhance the storability of Anxi persimmon fruit by regulating energy metabolism.
