Abstract:
Taking ‘Yuancui’ jujubes as test material,the colonization ability of antagonistic yeasts(Metschnikowia pulcherrima) on the surface of fresh jujubes was studied.The results showed that higher concentrations of M.pulcherrima (10.8cfu/mL) applied,and relative humidity （RH 95%~100%）in preservation period of fruit,the more favorably colonized M.pulcherrima on fresh jujues surface,the colonization ability of it was at 25℃ much more than at 5℃,preinoculation of pathogen had a negative effect of M.pulcherrima,Especially,the colonization ability of M.pulcherrima was decreased significantly then the inoculation the fungus 24 h after inoculation M.pulcherrima on fresh jujube surface.The synergistic factors could improve its colonizing ability,especially calcium propionate(0.2%w/v) could improve its colonizing ability stronger.
