阿魏酸与肉桂酸对杉木化感作用的生物评价

By bioassay of germination of Phaseolus aureus,Glycine max,Cucumis salivas,Brassica oleracea and Zea mays,the allelopathic of Ferulic acid and Cinnamic acid to Chinese-fir is analyzed.The results show that the high concentration of Ferulic acid inhibits the germination of the above vegetable seeds,while with the concentrations decreasing,the inhibited effects get weak.The high concentration of Cinnamic acid inhibits the effects on germination of Phaseolus aureus,Glycine max,Cucumis salivas and Zea mays seeds,while with its concentrations decreasing,the inhibited effects get weak also.However,the high concentration of Cinnamic acid shows a positive effect to Brassica oleracea.
