对冬枣贮藏期浆胞病病原微生物进行了连续系统的分离和鉴定,试验结果表明:贮藏冬枣浆胞病病原真菌主要为两种,半知菌亚门交链孢霉属(Alternaria Nees Wallr.)和半知菌亚门无孢菌群根菌索菌(Rhizomorpha Roth.ex Fr.);连续3年均分离到的贮藏冬枣浆胞病病原细菌有4种,对4种病原细菌进行了基因组DNA的提取及rDNA片段的扩增,并完成了062281菌株rDNA片段的序列测定,经过同源性分析,将062281号菌株鉴定为枯草芽孢杆菌Bacillus subtilis。 The results showed that there were mainly two kinds of pathogenic fungi which were stored in the jujube stage, Alternaria Nees Wallr. And half Rhizomorpha Roth.ex Fr., which contains 4 species of pathogenic bacterium isolated from jujube pasteuria for 3 consecutive years, extracted genomic DNA from 4 kinds of pathogenic bacteria, rDNA fragment was amplified, and the sequence of 062281 rDNA fragment was sequenced. After homology analysis, strain 062281 was identified as Bacillus subtilis.
