摘　　要：通过A n tim yc in A17对纯培养条件下及回接茄子褐纹病菌[P hom op sis vex ans(Sacc.et Syd)H arter]的影响,发现A n tim yc in A17对茄褐纹病菌菌丝及其甲型孢子都有较强的抑制作用,其抑制中浓度(EC50)分别为0.1000μg/mL和0.0166μg/mL;经A n tim yc in A17处理过的菌丝体所形成的甲型孢子,其萌发力和形态都较正常孢子有很大差别。Pure culture and reinoculation studies showed that Phornopsis vexans mycelium was very sensitive to Antimycin A17 in solid PDA culture medium and spores were much more sensitive to concentration EC50 of 0. 1000μg/mL and 0. 0166μg/mL. Spore＇s formation and its shape was affected after mycelium was treated with Antimycin A17.
