一株酵母菌的鉴定及其挥发性物质防病测定
Identification of a Yeast Strain and Effect of Its Volatile Organic Compounds on Disease Control
摘要
Abstract
To verify the biocontrol efficacy of antagonistic yeast fungus in control of strawberry gray mold disease,a yeast strain W4682 which was effective in inhibiting Botrytis cinerea in dual culture and suppressing gray mold disease on strawberry fruits with the live cells,was identified and the efficacy of its volatile organic compounds in control of strawberry gray mould was determined.As a result,the yeast strain W4682 was identi-fied as Debaryomyces hansenii.The volatile organic compounds produced by the strain W4682 could inhibit my-celial growth of Botrytis cinerea and suppress botrytis fruit rot in strawberry obviously.When the strain W4682 was inoculated on strawberry fruits,the yeast cells colonized on fruit surface and controlled the botrytis rot in these fruits effectively,at the same time,the volatile organic compounds produced by these fruits also effectively controlled the botrytis rot in other fruits under the same air-tight space which were not inoculated with yeast cells.This study suggests that the strain W4682 of Debaryomyces hansenii is a promising agent for the control of Botrytis cinerea.关键词
