Effect of Seedling Growth of NaCl Stress on Different Cucumber Species

'Jinza','Jinyou','Jinchun' series of 10 cucumber varieties were used as test material,the differences in salt tolerance of the different varieties of cucumber under NaCl stress were studied.The results showed that seed germination rate was not only with the cucumber salt tolerance varies,but also by changes in salt concentration changes.Concentration of 0.1% saline solution had no effect on seed germination rate,the concentration of 1% salt solution significantly affected the germination rate of cucumber seeds.Salt stress also significantly increased the relative conductivity of seedling leaves,reduced the relative water content in leaves and roots.After salt stress,which by the relative conductivity of cucumber seedlings increased by 50% to 100%.
