在离体条件下分析了油菜花瓣上影响核盘菌寄生菌-盾壳霉（Coniothyriumminitans）萌发的因子。结果表明，花瓣自身物质对盾壳毒无影响，花瓣微生物区系中的细菌不利于其萌发。链霉素可以抑制花瓣上细菌增殖，促进盾壳霉萌发。100－300μg／L链霉素对盾壳霉萌发无影响，30～1000μg／L链霉素溶液配制孢子悬浮液可以促进其在油菜花瓣上萌发。
In vitro, the factors influencing the germination of R. solanacearum Coniothyrium minitans were analyzed. The results showed that the material of petals had no effect on shield shell virus and the bacteria in the petal microbiota was not conducive to its germination. Streptomycin can inhibit bacterial proliferation on petals and promote the germination of C. fortunei. 100-300μg / L streptomycin had no effect on the germination of C. fortunei. Spore suspension was prepared with 30-1000μg / L streptomycin solution to promote its germination on petal petals.
