Abstract:
Using one year old seedling plants as tested materials，salt resistance of 5 kinds apple rootstocks(Malus robusta，Malus prunifolia，Malus sieboldii，Malus zumi，Malus micromalus) was compared by salt stress treatment.The results showed that with the increase of NaCl concentration，the shoot increment，leaf area，leaf thickness and root activity of the tested plants declined gradually；while salt injury index and its rate increased with the smallest increasing range for Ｍ.robusta and the biggest one for M.sieboldii.The content of chlorophyll and carotenoid varied in different treatments，with relative small variations for M.robusta and M.prunifolia.The contents of soluble sugar and MDA of the tested plants had a trend to increase with aggravation of salt stress，the activities of SOD and POD were affected in different degrees；M.robusta was the biggest and M.sieboldii was the smallest of the averange subordinate function.Comprehensive analysis the performance of the rootstocks with the indexes obtained in the test，salt resistance of the 5 apple rootstocks could be ranked as follows,M.robusta,Ｍ.micromalus,M.prunifolia,Ｍ.zumi,M.sieboldii.
