摘要: 采用LI-6400 便携式光合分析系统对裂叶沙参和泡沙参进行了不同遮光水平蒸腾速率的测定, 并同步测定了叶片气孔大小、气孔密度、气孔开度和气孔导度等气孔行为。采用相关系数和通径系数分析方法分析了不同遮光水平裂叶沙参和泡沙参气孔行为与蒸腾特性的关系。结果表明:不同遮光水平测定的气孔行为对裂叶沙参和泡沙参蒸腾作用的直接影响大致相同, 其中, 两种沙参的气孔密度对蒸腾速率的直接影响较大。但泡沙参的气孔导度与蒸腾作用具有极显著的相关关系。

Abstract: The transpiration rates of A.lobophylla and A.potaninii under different shape level were tested by use the LI-6400 convenient photosynthesis analysis instrument.In the meanwhile, the stomata behaviors such as stomatal size, stomatal density, stomatal open and stomatal conductivity were tested.By using the methods of path coefficient analysis and correlation coefficients, the relationships between stomata behaviors and transpiration of A.lobophylla and A.potaninii under different shape level were analyed.The results showed that there was roughly same influence on transpiration of A.lobophylla and A.potaninii by stomatal behaviors under different shape level.There was bigger inf luence on transpiration rare by stomata density of these two plants.There were significent correlations between stomata conductivity and transpiration of A. potaninii/i>.

Key words: Adenophora lobophylla, A.potaninii, stomata behavior, transpiration
