摘　　要：从北京部分地区萎蔫的茄子植株上分离到两种类型病原菌：茄子枯萎病菌（Fusarium oxysporum f．sp．melongenae）和黄萎病菌（Verticillium dahliae），并对其生物学特性进行了初步研究。结果表明，茄子枯萎病菌、黄萎病菌在PSA培养基上菌丝最适生长温度为20～25℃，pH6-7；枯萎病菌在PDA培养基上菌丝层厚且致密，黄萎病菌在VBC培养基上菌丝生长迅速但菌落稀薄；枯萎病菌氮源以蛋白胨为最佳，黄萎病菌碳源以蔗糖为最好，氮源以蛋白胨为最好。Two kinds of pathogens,Fusarium oxysporum f. sp. melongenae and Verticillium dahliae,were isolated from wilted eggplant in part of Beijing area. The results showed that in PSA medium, for Fusarium oxysporum f. sp. melongenae and VerticiUium dahliae, the optimum growth temperature is about 20 - 25 ℃, pH 6 - 7. Hyphae of Fusarium oxysporum f. sp. melongenae were thick in PDA medium. Hyphae of Verticillium dahliae grew rapidly in VBC medium. The optimum nitrogen source for Fusarium oxysporum f. sp. melongenae was peptone, the optimum carbon and nitrogen sources for Verticillium dahliae were sugar and peptone.
