| 摘 要： | 禾谷孢囊线虫病(简称CCN)是我国小麦产区主要的病害之一,对农业生产造成了极大的损失。该研究从禾谷孢囊线虫的孢囊上分离寄生性真菌,并对其进行室内防效测定。结果表明:从获得的20株真菌中,菌株Z2和Z4菌株对禾谷孢囊线虫病有较好的防治效果,防效均达50%。通过形态特征观察和ITS序列区测定,Z2和Z4两菌株分别归属为格孢腔菌目(Pleosporales)和拟青霉属(Paecilomycessp.),并对两菌株的生物学特性进行了初步的研究。

| Abstract: | Cereal cyst nematodes in the Heterodera avenae group are recognized as one of the important pest of wheat in China.In order to seek for the biocontrol agents for CCN,20 parasitic fungi were isolated from CCN cysts and eggs,which was evaluated in pots.Eleven isolates(Z2 and Z4) provided good control of CCN in pots,with average control efficacy reach 50%.Z2 and Z4 strains respectively belonged to Pleosporalesand Paecilomyces sp through morphological characteristics observation and ITS sequence assayed.Then it preliminary studied on the biological characteristics of the two strains. |
