| 摘 要： | 研究了洋葱油和大蒜提取物对灰霉菌分生孢子萌发、菌丝生长的抑制作用以及对草莓灰霉病的防治效果。结果表明，浓度为0.5 g?L-1的洋葱油和200 g?L-1的大蒜提取物即能抑制分生孢子的萌发；处理24 h后，洋葱油和大蒜提取物对灰霉菌菌丝生长有效抑制浓度分别为0.5和100 g?L-1，抑制率分别为89.3 %和85.9 %，48 h后有效抑制浓度分别为2.0和200 g?L-1，抑制率分别为90.5 %和85.6 %。然而在草莓灰霉病防治试验中，洋葱油和大蒜提取物都未表现出较好的防治效果。而化学杀菌剂Seibear能够抑制灰霉菌菌丝生长，并且对草莓灰霉病的防治效果较好，但是对灰霉菌分生孢子萌发的抑制作用不如洋葱油和大蒜提取物。

| Abstract: | Onion oil and garlic extraction were studied to test the inhibitory action on conidia germination,mycelium development and the control effect on gray mold disease with strawberry fruits.The results showed that onion oil of 0.5 g?L-1 and garlic extraction of 200 g?L-1 were effective enough to control conidia germination.In another experiment,after 24 h,onion oil of 0.5 g?L-1 and garlic extraction of 100 g?L-1 could effectively inhibit mycelium growth,the inhibitory rates(IRs)were 89.3 % and 85.9 % respectively.After 48 h,the effective concentrations of onion oil and garlic extraction were 2.0 g?L-1 and 200 g?L-1,the related IRs were 90.5 % and 85.6 %.Onion oil and garlic extraction didn’t work well to control gray mold.At the same time,we found that chemical fungicide(Seibear)showed better control efficiency against gray mold and inhibitory action on fungal mycelium development.But it didn’t express effective action on fungal conidia germination. |
