Abstract

Effects of salicylic acid(SA) on seeds germination and seedling growth of wheat under Cadmium(Cd2+) was studied.The changes of chlorophyll content,superoxide dismutase(SOD) activity,peroxidase(POD) activity,and malondialdehyde(MDA) content were tested.The results showed that germination rate,average root length and shoot length of wheat were inhibited under Cd2+ stress.The higher the Cd2+ concentration,the higher inhibition extent was.Meanwhile,SOD and POD activity and MDA content were increased;chlorophyll content was decreased.The germination rate,average root length,mean bud length and leaf chlorophyll content of wheat were increased by SA treatment.Moreover,the content of MDA was reduced;and SOD,POD activity were increased.SA could relieve the damage of Cd2+ on wheat seed and seedling to some extent.
