Abstract

Abstract: The effect of 1 μL/L 1-methylcyclopropene (1-MCP) on the softening of Nanguo pear fruits during postharvest storage at room temperature (23 ± 1) ℃ was studied. The results showed that 1-MCP treatment delayed the occurrence of ethylene peak and decreased its peak value, slowed down the decrease in fruit firmness and the increase in malondialdehyde content, significantly inhibited the activities of cellulase, polygalacturonase, pectin methyl esterase and amylase, retarded the increase in soluble pectin content, and simultaneously delayed the decrease in cellulose, protopectin and starch contents. Therefore, 1-MCP treatment could effectively slow down the softening process of postharvest Nanguo pear fruits and prolong its storage life.

Key words: Nanguo pear, 1-methylcyclopropene, softening, postharvest storage
