摘要
采用田间试验方法研究了"托鲁巴姆"叶片中黄酮类化合物对茄子黄萎病抗性及植株根际土壤微生物的影响。结果表明:"托鲁巴姆"叶片总黄酮对田间茄子黄萎病具有较好的预防效果。病菌侵染前,"托鲁巴姆"叶片总黄酮可以显著提高植株茎粗;病菌侵染后,总黄酮处理植株的茎粗和根长均显著高于对照(CK),株高显著低于CK。病菌侵染前,"托鲁巴姆"叶片总黄酮处理的茄子植株根际微生物总量、土壤细菌数量、放线菌数量和真菌数量均显著提高,但细菌与真菌数量的比值(B/F)和放线菌与真菌数量的比值(A/F)略有降低。病菌侵染后,"托鲁巴姆"叶片总黄酮处理植株的根际微生物结构基本保持稳定,较CK变化幅度明显减小,根际土壤放线菌数量和A/F较CK明显提高。
The method of field experiment was used to study the effects of flavonoids in leaves of Solanum torvum on eggplant＇s resistance to verticillium wilt and rhizosphere soil microorganism. The results showed that the flavonoids in leaves of Solanum torvum have good prevention effect on field eggplant verticillium wilt. Before the plant is infected, flavonoids contained in Solarium torvum leaves have a significant function on increasing the stem diameter of the plant. After the plant were infected, both stem diameter and root length of the treated plant were higher than that of CK and the height of plant were significantly lower than that of CK. By using flavonoids in leaves of Solanum torvum to process eggplant plants, the amount of rhizosphere microorganism, solt bactena, actinomycetes and fungus were significantly improved. But B/F and A/F were slightly reduced. After infection of verticillium dahliae, the structures of rhizosphere microorganism processed by flavonoids in leaves of Solanum torvum were remaining stable, the changing of which was significantly decreasing compared with CK. The number of rhizosphere soil actinomycetes and A/F were significantly higher than CK.
