摘　　要：针对北京地区主要快菜品种,利用PDA培养基培养自然干种子、无菌水洗涤处理的种子和1%NaClO处理的种子,开展带菌情况检测,并通过观察显微形态对优势菌群进行了初步鉴定。结果表明,10个快菜品种干种子总体携带的主要菌群依次为链格孢属(Alternaria spp.)、青霉属(Penicillium spp.)、曲霉属(Aspergillus spp.)、镰刀属(Fusarium spp.)真菌;无菌水洗涤后的种子及悬浮液中的优势菌群依次为链格孢属、青霉属、曲霉属真菌;1%NaClO处理的快菜种子的优势菌群为链格孢属真菌。其中,链格孢菌为快菜种传主要病原真菌。Detection of seed-borne fungi on major varieties of Brassica pekinensis in Beijing area were carried out through PDA plate methods. With microscopic observation, we also conducted preliminary identification of dominant species. The results showed that major fungi on 10 cabbage varieties were Alternaria spp., Penicillium spp., Aspergillus spp. and Fusarium spp. in order. Alternaria spp., Penicillium spp. Aspergillus spp. were the dominant fungi on sterile water washed seeds as well as in the suspension, and Alternaria spp. had been mainly detected on seeds treated by 1% NaClO. Among them, Alternaria were dominant pathogenic fungi species.
