分析了枯萎病菌侵染及氟乐灵诱发处理后，棉苗叶片和根茎部组织中可溶性酚和黄酮醇以及不溶性细胞结合酚（胞壁结合简单酚、胞壁结合复杂酚聚合物及胞壁结合黄酮醇）含量的变化．结果表明：抗病品种棉苗组织中酚类物质的含量高于感病品种棉苗中的含量，氟乐灵诱发处理促进了棉苗组织中酚类物质的积累；枯萎病菌侵染可明显提高棉苗体内的酚含量，但抗病品种棉苗及经氟乐灵诱发处理并产生诱导抗性的棉苗受侵后其组织中酚含量的增加幅度更大．由此认为，棉花体内的酚类物质与棉花对枯萎病的抗病性以及由氟乐灵诱发的诱导抗性有关．
After Fusarium oxysporum infection and trifluralin-induced treatment, soluble phenols and flavonols and insoluble cells in the leaves and rhizome tissues of cotton seedlings were bound to phenols (simple wall-bound phenolics, cell wall-bound complex phenols and cell wall binding Flavonol) content changes. The results showed that the content of phenolic compounds in cotton seedling tissues was higher than that in susceptible cotton seedlings. The treatment with trifluralin promoted the accumulation of phenols in cotton seedling tissues. The infection by Fusarium wilt could be significantly increased However, the content of phenol in cotton seedlings increased more after the inoculation of the resistant cotton seedlings and the cotton seedlings induced by trifluralin and inducing the resistance. Therefore, it is considered that the phenols in cotton are related to the resistance of cotton to Fusarium wilt and induced resistance induced by trifluralin.
