Suberin poly phenolic is an important component of healing tissue. We aimed to develop a new method to accelerate wound healing of harvested muskmelons. In this study, the plants and fruits of muskmelons were sprayed with 0.1 % chitosan four times during fruit development to evaluate the effect of chitosan treatment on wound healing of harvested muskmelons. The results showed that preharvest chitosan sprays reduced the weight loss and disease index of harvested muskmelons during healing. Chitosan sprays also accelerated the deposition of suberin poly phenolic at wound sites of harvested muskmelons during healing. The treatment increased the activities of phenylalanine ammonia-lyase and cinnamate-4-hydroxylase, and promoted the accumulation of cinnamic acid, caffeic acid, ferulic acid, p-coumaric acid, total phenols and flavonoids at wound sites. We suggest that preharvest chitosan sprays activated phenylpropanoid metabolism, promoted the deposition of suberin poly phenolic at wound sites of harvested muskmelons.

枯草多酚是治愈组织的重要组成部分。我们旨在开发一种新方法来加速收获的甜瓜的伤口愈合。在这项研究中，在果实发育期间四次向甜瓜的植物和果实喷洒0.1％的壳聚糖，以评估壳聚糖处理对收获的甜瓜伤口愈合的影响。结果表明，收获前的壳聚糖喷雾剂可减少愈合期间收获的香瓜的重量减轻和疾病指数。壳聚糖喷雾剂在愈合过程中还加速了木栓蛋白多酚在收获的香瓜伤口部位的沉积。该处理增加了苯丙氨酸解氨酶和肉桂酸-4-羟化酶的活性，并促进了肉桂酸，咖啡酸，阿魏酸，p的积累。-香豆酸，伤口部位的总酚和类黄酮。我们建议收获前的壳聚糖喷雾剂可激活苯丙烷类化合物的代谢，促进在收获的甜瓜的伤口部位沉积木栓蛋白多酚。
