Abstract:
Fusarium oxysporum f.sp.was used as research object,and growth rate method was adopted to study the allelopathy on watermelon Fusarium wilt of extracts from different parts of Chrysanthemum,in order to provide reference for the separation and purification of antibacterial active components in Chrysanthemum. The results showed that the three extracts of water extract had certain allelopathic effect on the growth of Fusarium oxysporum f.sp.,and the inhibition rates were 53%,49% and 45% at 100.00 mg?mL-1 treatment,respectively.There was no significant difference between the three parts according to Duncan′s variance analysis.With the decrease of the concentration of the extract,the inhibition rate showed a decreasing trend.The EC50 of the three parts was 86.256,84.648,106.876 mg?mL-1 by indoor virulence test.The results showed that the inhibitory effects of the extract of stems and leaves were higher.
