Chemical agents in the rhizosphere soils of plants might have an influence on root-rot disease, which therefore might reveal the mechanism of root rot in (). With this hypothesis the alterations of phenolic acids (PAs) in the rhizosphere soils of after pathogen infection were determined. The effects of PAs on the growth of (), a fungal pathogenic factor for , as well as production of fusaric acid, a wilting agent for the plants, were also examined. The results indicate the presence of five PAs (ferulic acid, syringic acid, -hydroxybenzoic acid, -coumaric acid, and vanillic acid) in the rhizosphere soils of , whose contents in the rhizosphere soils of healthy plants are higher than those of the diseased ones. Further we found that individual PA could inhibit the mycelium growth and spore production of , but stimulate fusaric acid production as well, disclosing the double-edge sword role of PAs in the occurrence of root rot of and paving the way for the intervention of root rot via balancing PAs.
植物根际土壤中的化学物质可能会影响根腐病，因此可能揭示了（）中根腐病的发生机制。基于这一假设，测定了病原菌感染后（）根际土壤中酚酸（PAs）的变化。还研究了 PAs 对（）生长的影响，（）是一种真菌致病因子，也是导致植物枯萎的枯萎酸的产生因素。结果表明，（）的根际土壤中存在 5 种 PAs（阿魏酸、丁香酸、-羟基苯甲酸、-香豆酸和香草酸），其在健康植物根际土壤中的含量高于患病植物。此外，我们发现，个别 PA 可以抑制的菌丝生长和孢子产生，但也可以刺激枯萎酸的产生，揭示了 PAs 在（）根腐病发生中的双刃剑作用，为通过平衡 PAs 干预（）根腐病开辟了道路。
