| Abstract: | For investigating the control efficiency of umbelliferone application on postharvest Botrytis cinerea in kiwifruit, the effects of umbelliferone treatment on B. cinerea spores and growth, the activities of defense related enzymes and the resistance-related substances after inoculation with B. cinerea in kiwifruit (Actinidia deliciosa. cv. Xuxiang) were studied during storage at room temperature. The results showed that 0.5 and 1.0 mg·mL-1umbelliferone effectively inhibited the spore germination and enlargement of colony diameter of B. cinerea in vitro. Also, the umbelliferone treatment with 0.5 and 1.0 mg·mL-1concentration reduced the expansion of the lesion area in kiwifruit inoculated with B. cinerea, and effectively increased the activities of defense-related enzymes, including chitinase (CHT), β-1, 3-glucanase (GLU), phenylalanine ammonia lyase (PAL), 4-coumarate CoA ligase (4-CL), peroxidase (POD) and polyphenol oxidase (PPO) in flesh of the kiwifruit, along with the increases in contents of resistant substances in treated kiwifruit, such as total phenolics, flavonoids and lignin, and thereby, decreased the incidence of gray mold in kiwifruit during postharvest. Our present work might provide a theoretical basis for the control of gray mold in kiwifruit by application of umbelliferone during storage. |
