- 摘要:
- 以黄菖蒲种子为试材，采用模拟水淹的方法，研究了0、7、14、21、28、35 d水淹对黄菖蒲种子的影响，以期为黄菖蒲广泛应用于三峡水库消落区人工植被修复提供参考依据。结果表明：黄菖蒲种子对水淹表现出一定的抗性，可利用到三峡水库消落区植被修复中。黄菖蒲种子经0~35 d不同时间水淹后，幼苗株高、叶片数、叶面积和根体积等形态特征，叶片叶绿素含量、根系和叶片可溶性糖和淀粉含量等生理特性以及各部分生物量和生物量比等均未随水淹时间呈明显变化趋势。
- Abstract:
- The Iris pseudacorus seeds were used as test materials，the use of simulated flooding method was used to study the effect of 0，7，14，21，28，35 days flooding on Iris pseudacorus seeds.In order to provide a scientific basis for Iris pseudacorus widely used in the drawdown area of the Three Gorges reservoir and artificial vegetation restoration.The results showed that the seeds of Iris pseudacorus showed some resistance on submergence，which could be used to the water-level-fluctuating zone of Three Gorges reservoir vegetation restoration.The seeds of Iris pseudacorus after 0-35 days different submergence duration，the morphological characteristics of plant height，leaf number，leaf area and root volume and the physiological characteristics of leaf chlorophyll content，root and leaf soluble sugar and starch content the biomass and its ratio had no obvious trend with the submergence time.
