| 摘 要： | 本文研究了出芽短梗霉Aureobasidium pullulans菌株Yw1防治储藏期草莓果实灰霉病Botrytiscinerea的效果，并对其防病机制进行了初步探索。结果表明，菌株Ywl可以有效的控制储藏期草莓灰霉病的发生，发病率可由95．1％降至30．5％-55．6％，菌株Ywl产生的挥发性物质可以抑制灰葡萄孢菌丝生长，抑制率达到52．1％。去除菌体的上清液对灰霉菌无明显抑制活性，说明其抗菌作用机制可能是活菌的竞争作用。由此可见，菌株Ywl是1株有应用潜力的生防菌。

| Abstract: | This study evaluated efficacy of Aureobasidium pullulans strain YW1 in suppression of post-harvest strawberry Botrytis fruit rot （BFR） caused by Botrytis cinerea and investigated its biocontrol mechanism. Results showed that strain YW1 effectively suppressed BFR on post-harvest strawberry fruits, and the disease incidence depressed from 95.1% to 30.5%--55.6%. The volatile organic compounds released by strain YW1 effectively suppressed mycelial growth of B. cinerea and the suppression ratio was 52.1%. Cell free supernatant of the YEPD culture of strain YW1 could not suppress the BFR, so may be strain YW1 out-compete B. cinerea on strawberry fruits depend on viable cells. This study suggests that the strain YW1 ofA. pullulans is a promising agent for control ofB. cinerea and further research is worthy. |
