图2 不同浓度NaCl处理15 d后6份材料的表型 A、B、C分别表示0、100和150 mmol L-1 NaCl处理15 d的表型特征, 比例尺为1 cm。D: 成苗率。E: 根鲜重。F: 地上部鲜重。G: 株高。H: 根干重; I: 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品种的不同浓度处理间在0.05水平上差异显著。

Fig. 2 Phenotypes of six materials after treatment with NaCl solution for 15 days A, B, and C refer to the phenotype after treatment with 0, 100, and 150 mmol L-1 NaCl for 15 days, respectively. Bar = 1 cm. D: seedling rate. E: fresh weight of root. F: fresh weight of shoot. G: shoot height. H: dry weight of root. I: 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 treatments of the same variety.
