摘要: 采用洗涤检验法和PDA培养基法对来自北京地区的16个生菜品种进行了种传真菌检测和优势菌群的初步鉴定。结果表明:干燥种子平均带菌率高达95.2%,携带的优势菌群依次分别为链格孢属(Alternaria spp.)真菌 82.8%、曲霉属(Aspergillus spp.)真菌13.7%、青霉属(Penicillium spp.)真菌4.4%和镰刀属(Fusarium spp.)真菌1.8%;无菌水洗涤后种子平均带菌率为89.1%,所携带的优势菌群依次分别为链格孢属真菌73.2%、曲霉属真菌17.1%、青霉属真菌7.2%和镰刀属真菌2.5%; 1%NaClO处理后的种子带菌率平均高达72.2%,优势菌群依次分别为链格孢属真菌75.6%、青霉属真菌10.8%和镰刀属真菌5.2%。

Abstract: By using seed washing and PDA plate methods, the seed borne fungi 16 varieties of lettuce seeds from Beijing were detected and the dominant microflora was identified preliminarily. The results indicated that Alternaria spp.(82.8%), Aspergillus spp.(13.7%), Penicillium spp.(4.4%)and Fusarium spp.(1.8%)were the dominant microflora of dry seeds and the germ-bearing rate of seeds was 95.2%. The germ-bearing rate of seeds washed with sterile water reduced to 89.1% and the dominant microflora were Alternaria spp. (73.2%), Aspergillus spp.(17.1%), Penicillium spp.(7.2%) and Fusarium spp.(2.5%). The germ-bearing rate of seeds treated by 1% NaClO was 72.2% and the dominant microflora of seeds sterilized in 1% NaClO were Alternaria spp.(75.6%), Penicillium spp.(10.8%)and Fusarium spp.(5.2%).
