The 59 pure cultural isolates, including 3 Fusarium oxysporum f.sp.cucumarinum, 26 other Fusarium isolates and 20 fungi, 6 bacteria, 7 actinomycetes from cucumber rhizosphere, have been detected by PCR-RFLP and Nested-PCR. It shows that PCR-RFLP is special for the pathogen of Cucurbits Fusarium Wilt, and Nested-PCR is special for Fusarium oxysporum f.sp.cucumarinum.

本论文应用PCR-RFLP和巢式PCR程序对3株黄瓜尖镰孢菌(Fusarium oxysporum f.sp.cucumarinum)、26株镰孢属部分真菌及分离自土壤的20株真菌、6株细菌和7株放线菌共59个菌株进行扩增，表明PCR-RFLP程序对瓜类枯萎病菌具有特异性，而巢式PCR对黄瓜尖镰孢菌具有特异性，巢式PCR程序检测黄瓜尖镰孢菌的特异性高于PCR-RFLP程序。

The primers and the detection programs have been used to detect the pathogens in the inoculated-diseased cucumber plants .The details are reported as follows: 1. By using the primers ITS1/ITS4, only Fusarium isolates could be amplified to produce a special fragment of 750bp. This product generated 480bp, 200bp and 100bp fragments after digested by restriction enzyme HinfⅠonly from the pathogen of Cucurbits Fusarium Wilt.

引物ITS1/ITS4只在镰孢属菌株上扩增到一条750bp分子片段，其他供试菌株无扩增条带产生，扩增产物经HinfⅠ酶解后，只有瓜类尖镰孢菌产生480bp、200bp和100bp 3条带，说明该PCR-RFLP程序对瓜类尖镰孢菌具有特异性；巢式PCR引物BIK1/BIK4和BIK2/BIK3只有在黄瓜尖镰孢菌菌株上扩增到一条800bp分子片段，其他菌株均无扩增条带产生，说明该巢式PCR程序对黄瓜尖镰孢菌具有特异性。
