咪鲜胺对糙皮侧耳(平菇)污染菌绿色木霉的抑制作用

Inhibitory Effect of Prochloraz on Trichoderma viride Contaminated Pleurotus ostreatus(Jacq:ex Fr.)Qu è l.

采用菌丝生长速率法测定咪鲜胺对绿色木霉(Trichoderma viride)和5个不同品种糙皮侧耳(Pleurotus ostreatus)(平菇)的菌丝生长抑制活性;采用滤纸片抑菌圈法测定了其对绿色木霉分生孢子萌发的影响。结果表明:咪鲜胺能够极显著地抑制绿色木霉菌丝生长和孢子萌发,EC50值分别为2.536mg·L-1和5.482mg·L-1。同时咪鲜胺对平菇的菌丝生长也有一定的抑制作用,在咪鲜胺有效浓度为8.333mg·L-1以下时抑制作用不显著;生料栽培试验也获得了相似的结果。

Prochloraz's activities on inhibiting the mycelium growth of Trichoderma viride and 5 different varieties of Pleurotus ostreatus(Jacq:ex Fr.)Quèl.were tested by the mycelium growth rate method and its effect on conidiophore germination of Trichoderma viride was tested by inhibition zone method.The results indicated that prochloraz could remarkably inhibit the growth of Trichoderma viride mycelium and spore germination.The EC 50 values were 2.536 mg.L-1 and 5.482 mg.L-1,respectively.Additionally,prochloraz could also inhibit the growth of Pleurotus ostreatus(Jacq:ex Fr.)Quèl.mycelium.There are less significant differences of inhibition to Pleurotus ostreatus(Jacq:ex Fr.)Quèl.when the effective concentration of prochloraz was below 8.333 mg.L-1,its inhibitory effect on the growth of Pleurotus ostreatus(Jacq:ex Fr.)Quèl.mycelium was not remarkable.
