通过离体试验筛选出9株防治柑桔采后茎端腐烂病的酵母拮抗菌，其中X-1、MA-2拮抗效果最好，混菌试验中5d后病原菌不生长，后续体内试验中Pg 2 -5拮抗效果最好;生防效果与拮抗菌浓度呈正相关，经形态学和生理生化鉴定，菌株Pg 2 -5为Candida ernobii Lodder Kreger-van Rij。
Nine yeast antagonists against postharvest stem-end rot disease of Citrus were screened by in vitro experiment,among which X-1,MA-2 played the best role,and pathogen didn't grow in the mixing experiment after 5 days.The strain Pg2-5 had the best effect on the disease during the following in vivo experiment;the disease was reduced by 56.67% to the control.And the biocontrol activity was positively correlated to the concentration of yeast antagonist,negatively correlated to the time of incubation.The strain Pg2-5 was identified as Candida ernobii Lodder Kreger-van Rij by morphological and physiological testing.
