Table 1 Symptoms of mungbean at seedling stage under salt stress

等级 Grade 耐盐性 Salt tolerance 表型特征 Symptom 1 高耐盐 Highly salt-tolerant 生长正常, 未出现盐害症状。 Normal growth, no symptoms were observed. 3 耐盐 Salt-tolerant 生长基本正常, 少数叶片边缘出现青枯或卷缩。 The growth is basically normal, and a few leaves appear withered or curled on the edge. 5 中耐盐 Mediumly salt-tolerant 叶片面积一半左右出现青枯或卷缩。 About half of the leaf area appear withered or curled. 7 敏感 Salt-sensitive 叶片大部分面积干枯坏死, 生长严重受阻。 Most of the leaves are dry and necrotic, and the growth is severely blocked. 9 高敏感 Highly salt-sensitive 严重受害, 植株完全枯萎。 Severely damaged, the plant is completely withered.
