Abstract:

This study aimed to compare the effects of chitosan (CTS) and chitooligosaccharide (COS) treatments on wound healing of pear fruits and to investigate the related mechanisms during postharvest storage under ambient conditions. The results revealed that CTS and COS treatments reduced the weight loss and disease index of the wounded pears (Pyrus bretschneideri cv. Dongguo), and accelerated suberin polyphenolic and lignin deposition at wounds during 7 d of investigation. Furthermore, CTS and COS elevated the level of the genes expression and activities of key enzymes and increased product contents of phenylpropanoid metabolism. Collectively, these treatments at a concentration of 1 g/L could promote wound healing in pears by activating phenylpropanoid metabolism. Comparatively, COS treatment presented better effects to CTS and could be useful as a preservative method to enhance storability of fresh produce.
