Abstract: Objective The aim of this study is to evaluate the salt tolerance of different processed tomato varieties in order to provide reference for the rational selection of varieties with good salt tolerance.MethodSeven tomato cultivars were used as materials to determine such physiological indicators as proline content, malondialdehyde, soluble sugar content,soluble protein content, SOD, POD, CAT activity of them under the stress of NaCl concentration of 100 mmol/L which were widely planted in Xinjiang.ResultThe activities of SOD, POD, CAT and soluble protein in proline, soluble sugar and antioxidant enzyme system were positively correlated with the salt tolerance of plants and the accumulation of malondialdehyde tolerance of plants was negatively related with to salt stress.And finally, the salt tolerance of 7 varieties was evaluated by the method of membership function.ConclusionThe salt resistance ability of seven processing tomato cultivars from strong to weak is: Nongfan 3 > IVF6172 >Shihong 9 >Tunhe17 >IVF3155 >PT501Q >JW001.
