| 摘 要： | 以塔中沙漠植物园引种成功的4种豆科植物紫穗槐(Amorpha fruticosa)、花棒(Hedysarum scoparium)、白柠条(Caragana korshinskii)和骆驼刺(Alhagi sparsifolia)的幼苗为实验材料, 研究不同NaCl浓度处理30天其叶绿素荧光参数、叶绿素含量及叶片水势的变化特征。结果表明: 在不同浓度NaCl处理下, 骆驼刺和白柠条幼苗的叶绿素荧光参数、叶绿素含量及叶片水势的变化程度均低于紫穗槐和花棒; NaCl处理后骆驼刺和白柠条均具有较稳定的光合生理特征, 紫穗槐和花棒的稳定性则相对较差; 在NaCl处理时, 植物叶片水势的变化规律与叶绿素荧光参数具有一定的相关性, 它们可以反映幼苗对NaCl处理的不同响应。 |
| 关 键 词： | 叶绿素a含量 叶绿素荧光 叶片水势 豆科植物幼苗 盐分胁迫 |

| Abstract: | We investigated the effect of 30-day NaCl treatment on chlorophyll fluorescence variables, chlorophyll content and water potential in 4 legume seedlings, Amorpha fruticosa, Hedysarum scoparium, Caragana korshinskii and Alhagi sparsifolia, introduced in Tazhong Botanical Garden, Xinjiang, northwestern China. NaCl did not change chlorophyll fluorescence values, chlorophyll content, or leaf water potential in C. korshinskii and A. sparsifolia, but the results were opposite for A. fruticosa and H. scoparium. C. korshinskii and A. sparsifolia showed more stable photosynthetic and physiological characteristics than A. fruticosa and H. scoparium with NaCl. Leaf chlorophyll content and water potential were related in part to chlorophyll fluorescence values with 30-day NaCl treatment and may be used to indicate plant responses to NaCl. |
