研究了不同浓度NaCl处理对浙杂204、浙杂502和浙杂809共3个番茄品种生育期、主要植株性状、果实性状及产量的影响。结果表明,3个番茄品种的生育期在盐胁迫下较CK而缩短;产量随着NaCl处理浓度的升高而显著减小;可溶性固形物含量随NaCl处理浓度的升高而有所增加,其中,浙杂809可溶性固形物含量随着NaCl处理浓度的升高增加最大;3个供试品种的耐盐性,从强到弱依次是浙杂809、浙杂204和浙杂502。120 mmol.L-1浓度可以作为番茄品种的耐盐性参考筛选浓度。
The effects of different NaCl concentrations on the growth, main plant characters, fruit traits and yield of three tomato cultivars Zhezza 204, Zheza 502 and Zheza 809 were studied. The results showed that the growth stages of three tomato varieties were shorter than CK under salt stress; the yield decreased significantly with the increase of NaCl concentration; the content of soluble solids increased with the increase of NaCl concentration, of which, The content of soluble solids of Zheza 809 increased most with the increase of NaCl concentration. The salt tolerance of three tested cultivars was Zhaza 809, Zheza 204 and Zheza 502,120 mmol from strong to weak. The concentration of L-1 can be used as a salt tolerance reference tomato screening concentration.
