| 摘 要： | [Objective] The research aimed to lay a foundation for the screening of cell lines producing secondary metabolites of Brucea javanica(L.)Merr.[Method] The insecticidal activities of the extracts from branch and 3 different types of calluses of Brucea javanica(L.)Merr.was detected through methods of leaf disc and potted seedlings against the diamond back moth.[Result] Extracts from four kinds of Brucea javanica(L.)Merr.tissues assumed both the activities of antifeedant and oviposition deterrency against the diamond back moth.Antifeedant effect of extracts was in turn the callus C< callus B< callus A< branches.Oviposition deterrency activity of the extracts was in turn the callus A> branch > callus B>callus C.The insecticidal activities of callus A and B were higher than that of the callus C.[Conclusion] The results show that insecticidal activity of callus and its growth rate is inversely proportional.

| Abstract: | [Objective] The research aimed to lay a foundation for the screening of cell lines producing secondary metabolites of Brucea javanica(L.)Merr. [Method] The insecticidal activities of the extracts from branch and 3 different types of calluses of Brucea javanica(L.)Merr. was detected through methods of leaf disc and potted seedlings against the diamond back moth. [Result] Extracts from four kinds of Brucea javanica(L.)Merr. tissues assumed both the activities of antifeedant and oviposition deterrency against the diamond back moth. Antifeedant effect of extracts was in turn the callus C< callus B< callus A< branches. Oviposition deterrency activity of the extracts was in turn the callus A> branch > callus B>callus C. The insecticidal activities of callus A and B were higher than that of the callus C. [Conclusion] The results show that insecticidal activity of callus and its growth rate is inversely proportional. |
