Phenotypes of Shanyou 10 and Liangyoupeijiu seedlings after salt stress. (A) Phenotypes of 10-day-old seedlings of Shanyou 10 and Liangyoupeijiu after salt stress (100 mM NaCl), as indicated by (+), or under normal conditions (no NaCl), as indicated by (-). (B) Relative length of shoots and roots of Shanyou 10 and Liangyoupeijiu seedlings. (C) Relative dry weight of shoots and roots of Shanyou 10 and Liangyoupeijiu seedlings. The distance from the basal part of shoot to tip of the longest leaf was calculated as the length of seedling. The percentage of relative FW, DW, or shoot/root length of the salt treated samples was calculated in relation to non-treated. Data represent the average of four treatments (mean ± S.E.). Identical letters above a pair of bars indicate that the values are not significantly different at the p = 0.05 level according to Duncan's multiple range test.
