图3 150 mmol L-1 NaCl处理下6份材料的耐盐性 ST_SR: 相对成苗率; ST_H: 相对株高; ST_FWR: 相对根鲜重; ST_FWS: 相对地上部鲜重; ST_DWR: 相对根干重; ST_DWS: 相对地上部干重; 数据结果为3次生物学重复, 误差线为标准误(n = 3); 标以不同小写字母的柱值在同一指标的不同品种间在0.05水平上差异显著。

Fig. 3 Salt tolerance of six materials under 150 mmol L-1 NaCl stress ST_SR: relative seedling rate; ST_H: relative height; ST_FWR: relative fresh weight of root; ST_FWS: relative fresh weight of shoot; ST_DWR: relative dry weight of root; ST_DWS: relative dry weight of shoot. Data are mean ± SE with three biological replicates (n = 3). Bars superscripted by different letters are significantly different at P < 0.05 between different varieties of the same indicator.
