| 摘 要： | 用盆栽控水的方法模拟土壤干旱条件,从水分生理和光合作用方面对两种驼绒藜属植物的抗旱生理进行研究。试验结果表明,华北驼绒藜的水分生理指标普遍高于绵毛优若藜,在水分胁迫状态下,华北驼绒藜的光合作用要比绵毛优若藜强。初步认为华北驼绒藜具有较强的抗旱能力。

| Abstract: | Drought resistance and photosynthesis of two species of Ceratoides under the condition of artificial soil desiccation were studied based on some indexes of water and photosynthesis. The results showed that all water parameter of Ceratoides arborescens were higher than that of Ceratoides lanata, and the photosynthetic rate of C. arborescens was also higher under water stress. It was considered that the C. arborescens has higher drought resistance capability. |
