Abstract

Eight tomato cultivars were treated with 5 Na2CO3 densities in bud stage.The water was took as the CK.The results indicated that SOD content increased first,then fallen in the bud stage with the Na2CO3 increase;under the high Na2CO3 stress,proline,soluble sugar,POD content kept the high level,this showed that the high salty stress was serious to the plant's injury.The tolerance to salt of Shennv,Shennongdahong,and Zimei was strong,Fenhong Tomato,Xifan 206 Tomato,Jiafen was medium and Yueguang Tomato,L-402 was weak.The sensitive of salty stress varied in the 8 tomato cultivars.
