| 摘 要： | 在in vivo和in vitro条件下测试了酵母菌3SJ对青霉菌(Penicillium expansum)、友霉菌(Botrytis cinerea)和炭疽菌(Colletotrichum)3种苹果采后致病菌的抑制效果.结果表明,在20℃下,酵母菌3SJ对青霉菌和灰霉菌抑制效果较好,对炭疽菌的防治效果稍差.在苹果伤口接种酵母菌孢子悬浮液能有效抑制苹果的腐烂,而上清过滤液和灭菌液不能抑制苹果的腐烂,说明酵母菌3SJ的作用机制主要是营养竞争.在4℃低温条件下,酵母菌3SJ可以在苹果伤口上存活30d以上,且数量增加,其耐低温性为酵母菌在果品低温冷藏中的应用奠定了基础.

| Abstract: | The in vivo and in vitro biocontrol efficacy of yeast 3SJ on postharvest disease of apple(Fuji) caused by Penicillium expansum,Botrytis cinerea and Colletotrichum were tested.At 20 ℃,the biocontrol efficacy of yeast against Penicillium expansum and Botrytis cinerea was retalively good.But the control efficacy of yeast against Colletotrichum was not good.On the apple wound,the spore suspension of yeast could effectively prevent decay;while the filtrate and sterilization liquid couldn’t prevent decay,indicating that the action mode of yeast is mainly nutrition competition.at 4 ℃,yeast 3SJ could live for at least 30 d in apple wound;and the amount was increased.The property of low temperature resistance of the yeast established the basis for its application in fruit storage at low temperature. |
