摘  要：
采用生长速率法和孢子萌发法测定了细辛精油对引起黄瓜病害的5种病原菌的菌丝生长和孢子萌发的影响。结果表明,对灰霉病菌菌丝生长和孢子萌发的抑制效果均较好,其次是对褐斑病菌、枯萎病菌和叶斑病菌;而对根腐病菌菌丝生长和孢子萌发的抑制效果均较差。对于同一种病原菌来说,细辛精油对其孢子萌发的抑制效果和对其菌丝生长的抑制效果存在差异,如灰霉病菌和根腐病菌,对其孢子萌发的抑制效果好于对其菌丝生长的抑制效果。

摘  要：
The effects of asarum essential oil on hypha growth and spore germination of five pathogens (Botrytis cineroa, Cercospora citrullina,Corynespora cassiicola,Fuarium axysporum,Fusarium solani)in cucumber were studied in this paper.The growth rate method and spores germination method were used to determine the activities.The results showed that the asarum essential oils hads significant antibacterial activity on tested pathogens,while effects on hypha growth of Cercospora citruUina,Corynespora cassiicola and Fuarium axysporum were higher than that on spores germination,and on spores germination of Botrytis cinerea and Fusarium solani were higher than that on hypha growth.The effect on hypha growth and spores germination of Botrytis cinerea was the best,EC_(50)<160 mg/L and EC_(90)<350 mg/L.The effect on hypha growth and spores germination of Botrytis cinerea was the worst,EC_(50)>700 mg/L and EC_(90)>2 000 mg/L.
