| 摘 要： | 为了了解水分胁迫对植物表皮蜡质含量的影响及叶片表皮蜡质含量与植株抗旱性的关系，采用裂区设计研究抗旱能力不同的4个大麦品种从植株挑旗期到成熟期的旗叶及旗叶鞘表皮蜡质含量的变化趋势，探讨大麦叶片的表皮蜡质含量与抗旱能力的关系及机理。结果表明，干旱胁迫下大麦叶片表皮蜡质含量增加，随着植株生长发育及干旱胁迫程度的增加，其变化趋势表现为先上升后下降。抗旱能力不同的大麦品种表皮蜡质含量变化趋势相似，然而，抗旱品种的叶片表皮蜡质含量的变化强度较弱抗旱性品种的大。干旱胁迫初期，抗旱品种表皮蜡质变化明显，推测叶片表皮蜡质含量迅速增加可能是植物响应外界不良环境自我调节的表现之一。

| Abstract: | In order to understand the relationship between the leaf layer of epicuticular wax and plant drought resistance,the paper studied the variation of epicuticular wax content in flag leaf and layer of flag leaf of four barley varieties,using split plot experiment design,from flagging stage to the mature stage. The results showed that,the epicuticular wax content of barley leaves increased and then decreased with plant growth under the condition of drought stress. The variation of epicuticular wax content of leaves exhibited similar tendency,but the drought tolerant variety had larger variation extent than the drought sensitive variety. The epicuticular wax of leaves in drought tolerant variety changed obviously at the early stage of drought stress,which speculated that the rapid increase of epicuticular wax might be one of plant responses to environmental stress. |
