Abstract: The effects of Lactobacillus plantarum XCT 1-10 at different concentrations (0, 102, 104, 106, 108, and 1010 CFU/mL) on the colony growth and spore germination of Botrytis cinerea and the decay of apples inoculated with B. cinerea were investigated in this study. The results demonstrated that L. plantarum XCT 1-10 at 106 CFU/mL significantly restrained lesion development in apple fruit inoculated with B. cinerea, and distinctly depressed the spore germination and colony growth of B. cinerea. The in vitro test demonstrated that L. plantarum XCT1-10 treatment increased the contents of malondialdehyde (MDA), soluble sugar and soluble proteins, and nucleic acid release, but decreased the relative conductivity of B. cinerea. These findings suggest that L. plantarum XCT 1-10 can suppress the growth of B. cinerea possibly by destroying the cell membrane.
