图1 苗期耐盐性单株分类记载法的标准 1: 高耐盐, 生长正常, 未出现盐害症状; 3: 耐盐, 生长基本正常, 少数叶片边缘出现青枯或卷缩; 5: 中耐盐, 叶片面积一半左右出现青枯或卷缩; 7: 敏感, 叶片大部分面积干枯坏死, 生长严重受阻; 9: 高敏感, 严重受害, 植株完全枯萎。

Fig. 1 Standard of individual classification for salt tolerance at seedling stage 1: highly salt-tolerant, normal growth, no symptoms were observed; 3: salt-tolerant, the growth was basically normal, and a few leaves appeared withered or curled on the edge; 5: mediumly salt-tolerant, about half of the leaf area appeared withered or curled; 7: salt-sensitive, most of the leaves were dry and necrotic, and growth was severely blocked; 9: highly salt-sensitive, severely damaged, the plant was completely withered.
