） Abstract： This study was conducted to evaluate the efficacy of the biocontrol yeast Cryptococcus laurentii and calcium chloride (CaCl2) in suppressing the blue and gray mold rots of pear and to explore possible mode of action involved
The results showed that the combined treatment of pear fruit wounds with C
laurentii and CaCl2 at 2% (w/v) resulted in a significantly improved inhibition of Penicillium expansum and Botrytis cinerea infections in comparison with the application of C
laurentii alone
CaCl2 neither affected the growth of C
laurentii in vitro or in vivo, nor directly inhibited the blue mold in pear fruit wounds, however, it induced the fruit resistance to the blue mold rot when the time interval between CaCl2-treatment and pathogen-inoculation was up to 24 h, being associated with an activation of the peroxidase activity of pear fruit
Therefore, it could be concluded that the mechanism by which CaCl2 reinforced the biocontrol efficacy of C
laurentii against the mold infections was mainly due to its ability to inducing the fruit natural resistance
