摘要 土壤微生物群落对于农业系统的功能至关重要，但关于化感物质对土壤微生物体内影响的信息很少。用不同浓度的香草醛（0.02-0.2 μmol/g土壤）处理土壤中生长的黄瓜幼苗，香草醛是一种具有自毒活性的酚类化合物。镰刀菌和木霉属的群落结构和丰度。分别采用聚合酶链式反应（PCR）-变性梯度凝胶电泳和定量PCR对黄瓜根际中的细菌进行了分析。结果表明，香草醛改变了镰孢菌和木霉属的群落结构。香草醛减少了镰刀菌属的条带数量，但增加了木霉属的条带数量、香农-维纳指数和均匀度指数。 (p < .05)。所有浓度的香草醛都会促进镰孢菌和木霉属的丰度。 (p< .05)，并且这种刺激作用随着香草醛浓度的增加而增强。总体而言，这项研究提供了主要证据，表明香草醛改变了镰孢菌和木霉属的群落结构和丰度，并且这两个微生物群对香草醛表现出不同的反应。
ABSTRACT Soil microbial communities are crucial to the functioning of agricultural systems but little information is available on the effects of allelochemicals on soil microorganisms in vivo. Cucumber seedlings grown in soil were treated with different concentrations of vanillin (0.02–0.2 μmol/g soil), a phenolic compound with autotoxic activity. The community structures and abundances of Fusarium and Trichoderma spp. in cucumber rhizosphere were analyzed by polymerase chain reaction (PCR)-denaturing gradient gel electrophoresis and quantitative PCR, respectively. Results showed that vanillin changed the community structures of Fusarium and Trichoderma spp. Vanillin decreased the number of bands of Fusarium spp., but increased the number of bands, Shannon–Wiener and evenness indices of Trichoderma spp. (p < .05). Vanillin at all concentrations promoted the abundances of Fusarium and Trichoderma spp. (p < .05), and this stimulating effects increased with increasing concentration of vanillin. Overall, this study provided primary evidence that vanillin changed the community structures and abundances of Fusarium and Trichoderma spp., and that these two microbial groups showed different responses to vanillin.
