| 摘 要： | 为给小麦抗旱鉴定指标的早期筛选、小麦品种的培育与利用提供科学依据,在聚乙二醇(PEG-6000)水分胁迫条件下研究了6个不同肥水类型小麦品种幼苗期叶片生理生化的变化。结果表明,小麦品种随着水分胁迫时间的延长,幼苗干旱存活率、根冠比和叶绿素含量均降低,脯氨酸含量和细胞质膜相对透性均升高,根系活力先呈现略微升高再下降的趋势。旱地品种‘青麦6号’、‘济旱5034’和‘鲁麦21’的幼苗干旱存活率、根冠比、叶绿素含量和SOD活性较高且下降较为缓慢,而细胞质膜相对透性较低;高肥水品种‘烟农24’和‘济麦22’受水分胁迫影响较大,上述抗旱指标变化幅度较大;中肥水品种‘烟农21’的上述抗旱指标变化幅度介于高肥水和旱地品种之间。‘青麦6号’具有较高的抗旱指数,在水分胁迫条件下能够保持较好的叶片结构和功能状况,因而抗旱性较强。

| Abstract: | In order to provide scientific basis for early screening of wheat drought-resistant identification indices,and cultivation and utilization of wheat cultivars.A field trial was conducted to study the physiological and biochemical changes in leaves of six wheat cultivars (such as ' Qingmai No.6 ' ,' Jihan 5034 ' and ' Lumai 21 ' ) with different fertilizer and water types under PEG-6000 stress.The seedling survival percentage,root: shoot ratio and chlorophyll content all decreased,while the proline content an... |
