Abstract:
With Brassica oleracea L.var.botrytis L.as test material，the physiological and biochemical response of Zn2+ stress to its seeds were studied.The results showed that Zn2+ stress exhibited high inhibitory effects on Brassica oleracea L.var.botrytis L.The plant seeds germination rate decreased with the increase of Zn2+ concentration，but there was no obvious change.With the increase of Zn2+concentration，the root length，contents of chlorophyll decreased obviously.The activities of SOD and POD tended to firstly decrease then increased with the increase of Zn2+concentration and the contents of MDA and Pro tended to increase.The root vigor decreased gradually with the increasing of Zn2+concentration.
