摘要: 为探讨西芹种子浸提液对黄瓜枯萎病菌致病力的影响,采用液体培养法研究黄瓜枯萎病菌经西芹种子浸提液化感作用后菌体分泌的细胞壁降解酶活性及毒素(镰刀菌酸)含量变化,结果表明,各浸提液处理后,黄瓜枯萎病菌分泌的3种细胞壁降解酶(果胶酶、纤维素酶、β-葡萄糖苷酶)的活性较对照降低,其产生的镰刀菌酸含量较对照分别降低了20.02%、31.50%、34.18%。说明西芹种子各浸提液中含有的化感物质抑制了黄瓜枯萎病菌分泌的水解酶活性,并阻碍了黄瓜枯萎病菌镰刀菌酸的分泌,减弱了其对寄主的致病能力。

Abstract: To investigate the effects of the extracts solution of parsley seed on the pathogenicity of Fusarium oxysporium f.sp. cucumerinum, the change of the activity of the three cell wall-degrading enzymes and content of the toxins (fusarinic acid) of Fusarium oxysporium f.sp. cucumerinum were studied by the methods of liquid culture. The result showed that, the activity of the three cell wall-degrading enzymes (pectinase, cellulase,β-glucosidase) secreted by cucumerinum was lower than the control after the extract treatment. And the contents of the toxins (fusarinic acid) produced by cucumerinum lower by 20.02%, 31.50% and 34.18% than the control. So allelochemicals of the eextracts solution of parsley seed inhibited the activity of cell wall hydrolase, and impeded the contents of fusarinic acid, and weakened the ability of pathogenicity to host.
