摘要
采用生长速率法和孢子萌发法测定了地肤子、丹皮、落地生根等6种水提物对引起黄瓜黑星病的黑星病菌菌丝生长和孢子萌发的作用。结果表明:6种水提物对黑星病菌的菌丝生长和孢子萌发均有一定的抑制作用,且对孢子萌发的抑制活性好于对其菌丝生长的抑制活性。地肤子和丹皮水提物抑菌活性较好,对菌丝生长的EC50值分别为8.95、11.58g/L,对孢子萌发的EC50值分别为2.09、16.21g/L。
This article was determined the effect of mycelial growth and spore germination about six kinds of aqueous extracts including Kochia scoparia,Bryophyllum pinnatum,Paeonia suffruticosa and so on using mycelial growth and spore germination method.The result showed that there was a certain inhibition on cucumerinum,and the inhibitory activity on spore germination was better than mycelial growth.The antibacterial activity of aqueous extract of Kochia scoparia and Paeonia suffruticosa was highest,with EC 50 valu...
