摘  要:
本试验利用生长速率法研究了西芹鲜根乙醇浸提液对黄瓜枯萎病菌的化感作用。试验结果表明,西芹根乙醇浸提液在所试浓度范围内均表现为对黄瓜枯萎病菌不同程度的化感抑制作用,其抑制率最高达42.31%,最低为12.22%;并且除了1%浓度的处理在作用时间为120h,132h时菌落直径与对照ck无显著差异外,其余各浓度的处理在不同作用时间里对黄瓜枯萎病菌都有显著或极显著的化感抑制作用。乙醇浸提液对黄瓜枯萎病菌的化感效果有随着浓度的降低和作用时间的增加而逐渐减弱的趋势。

摘  要:
In the study,the allelopathy of the ethanol extract of the root of parsley on Fusarium oxysporiumf.sp.cucumeris was studied by growth rate method.The result showed that the ethanol extract of the root of parsley inhibited the growth of Fusarium oxysporiumf.sp.cucumeris significantly within the range of experimental concentration except the concentration of 1% in 120 hours and 132 hours,and its highest inhibitory rate was 42.31%,or lowest rate was 12.22%.there was a tendency that inhibitory rate of ethanol extract of root agaist Fusarium oxysporiumf.sp.cucumeris dropped down with decreasing concentration and prolong time.
