| 摘 要： | 利用来自不同地域的淡紫拟青霉的13个菌株，分别用其孢子液处理南方根结线虫分散卵粒、菌丝处理分散卵粒、孢子液处理卵囊以评价淡紫拟青霉对南方根结线虫的寄生性。在被试所有菌株中，同一菌株三种不同方法对根结线虫卵的寄生率相比，孢子液处理卵囊均明显高于其他两种处理。不同菌株对南方根结线虫卵的寄生率有很大的差异。三种处理方法结果显示618号菌株寄生率均为最高。菌株对卵的寄生率与菌株地理来源无明显相关性。

| Abstract: | This study was conducted to assess the parasitism of 13 isolates Paecilomyces lilacinus originating from difference areas on eggs of Meloidogyne incognita.The assay included three treatments:individual eggs treated by spore suspension,individual eggs treated by hypha of fungus,and egg masses treated by spore suspension.Parasitic rate of the same one of all isolates differed in 3 treatments, in which parasitic rate treated by spore suspension was much higher than that in the other two treatments. The results indicated that egg parasitic rate differed significantly among 13 isolates. In the three treatments, parasitic rate of isolate 618 on Meloidogyne incognita eggs was the highest. Parasitic rates of 13 isolates had not relation to the geographical resources of isolates. |
