摘 要：Objectives:The gray mold fungus Botrytis cinerea(***)infects a wide range of crops before and after harvest,causing huge losses *** mechanisms of *** in vitro and in plants by calcium propionate(CP),generally recognized as a safe substanee,are described in this *** and methods:Wild-type and transgenic mutant strains of *** were used in the study to evaluate the effects of CP on fun gal growth and developme nt in *** materials in cludi ng tomato leaves and table grapes were tested for con trolling efficie ncy of CP agai nst gray mold deterioration in ***:Mycelial growth of *** was inhibited by CP in a dose-dependent manner with occasional disruption of hyphal tips,causing cellular collapse and efflux of cell *** with fluorescein diacetate and propidium iodide indicated that CP decreased fungal cell *** efficiency of CP against *** was enhaneed by reducing *** contrast,the veil mutant,which exhibited deficiency in acid production,was more resista nt to CP,suggesti ng that inhibition of *** by CP is enhanced by the acidification ability of the fungus ***,CP inhibited infection cushion development by germlings of *** assays with tomato leaves and table grapes showed that CP inhibited decay development in both host ***,application of CP on grapes 3 days prior to harvest could contribute to management of deterioration caused by spontaneous fungal diseases during ***:CP can suppress hyphal growth,inhibit infection cushion development,and reduce the virulence of *** is thus promising for practical management of gray mold in fruit crops and merits further evaluation.
