| 摘要: |
| 为研究山西省不同小麦品种的耐盐性以及筛选适用于山西盐碱地种植的小麦品种，本研究以40个山西省各麦区主推的小麦品种为材料，分别在芽期和苗期对其进行盐胁迫(1.2% NaCl)处理，分析盐胁迫对小麦芽期和苗期各形态指标的影响，并利用耐盐性综合评价值(D)，对供试材料的耐盐性进行评价。结果表明:除芽期根鲜重和苗期根数以外，小麦芽期和苗期的各项形态指标均受到盐胁迫的影响，但不同指标对盐胁迫的敏感度存在差异；共筛选出芽期耐盐型品种9个，占供试材料的22.5%，苗期耐盐型品种11个，占供试材料的27.5%；芽期和苗期皆为耐盐型的材料5份，分别为‘石农086’‘临糯88’‘品育8161’‘冬黑1206’‘品育8012’。本研究结果可为山西省盐碱地小麦生产用种以及耐盐性小麦的培育提供材料基础。 |

| Abstract: |
| In order to study the salt tolerance of different wheat varieties in Shanxi Province and screen wheat varieties suitable for planting in saline-alkali land in Shanxi Province, 40 wheat varieties mainly promoted in different wheat regions of Shanxi Province were used as materials. These wheat varieties were treated with salt stress(1. 2% NaCl)at the germination and seedling stages, respectively. The effects of salt stress on various morphological indexes of wheat were analyzed at the germination and seedling stages. The salt tolerance comprehensive evaluation value(D)was adopted to evaluate the salt tolerance of tested materials. The results showed that: Except the root fresh weight at the germination stage and the number of roots at the seedling stage, all morphological indexes at the germination stage and seedling stage of wheat were affected by salt stress, but the sensitivities of different indexes to salt stress were different. A total of nine salt-tolerant varieties at the germination stage were identified(accounting for 22. 5% of the tested materials), eleven salt-tolerant varieties at the seedling stage(27. 5%), and five salt-tolerant materials, ‘Shinong086' ‘Linnuo88' ‘Pinyu8161' ‘Donghei1206' ‘Pinyu8012', were salt-tolerant at both the germination and seedling stages This study provides material basis for the production of wheat seeds in saline-alkali land and the cultivation of salt-tolerant wheat in Shanxi Province. |
