| 摘要： Fruits are one of the major economic commodities worldwide and postharvest rot diseases is one of the major problems that led to decreasing fruit production. Fungal contaminants reduce the quality of fresh fruits after harvest and it is one of the leading causes of economic loss in global fresh fruits. The purpose of this research was to isolate and identify pathogens causing postharvest rots on common fruits available in markets in Panlong District, Kunming, Yunnan Province, China. The fruits viz. apple (Malus domestica), dragon fruit (Hylocereus undatus), peach (Amygdalus persica) and pear (Pyrus sorotina) were selected to examine post-harvest rots since they are commonly available fruits in Yunnan markets. We isolated six fungal strains from the above-mentioned fruits. The pathogenicity tests and phylogenetic analyses were carried out for the fungi isolated from fruits. Our results showed that Fusarium spp. are common on apple, peach and dragon fruit. In the pathogenicity test, Monilinia yunnanensis inoculated on the pear had the strongest effect on the pear, and the disease spot expanded over half of the total area of the fruit. Our results are expected to provide a reference and basis for preventing postharvest diseases of common fruits in Yunnan. |
