| 摘 要： | 在虫害条件下，青菜释放出的挥发性化学物质成分较多．其中饱和烷烃类物质占多数，其次是芳烃类物质，其它为少量的不饱和烷烃、醛、醇、酮、酸和杂环化合物等．经小菜蛾取食危害的青菜释放的挥发性物质的量比未受损伤的青菜高3倍，且挥发性物质种类也多些．前者的挥发性物质多为分子量较小的物质，后者的挥发性物质多为分子量较大的物质．

| Abstract: | The study showed that Chinese cabbage,Brassica campestris could release a variety of volatiles,especially when infested by Plutella xylostella larvae.Among these volatiles,saturated hydrocarbon was dominant,aromatic hydrocarbon was the second,and unsaturated hydrocarbon,aldehyde,alcohol,ketone,acid and heteroaromatic compounds were existed with a small amount.Chinese cabbage damaged by Plutella xylostella larvae produced 3 times of volatiles in amount with more species than the control.The volatiles from control plants were mostly of small molecular weight,and those from Chinese cabbage damaged by Plutella xylostella were mostly of high molecular weight. |
