| 摘 要： | 臭椿苗木在水分胁迫下,相对含水量、叶绿素含量降低,质膜进性增大。随着水分胁迫时间的延长,苗木这几项生理指标所受的影响程度也加重。臭椿不同年龄阶段的苗木抗性不同。叶片质膜透性、相对含水量、叶绿素含量等指标,可作为评价臭椿苗木早期抗旱生理指标。 |
| 关 键 词： | 抗旱性 饱和水分亏 水分胁迫 臭椿 幼苗 生理指标 质膜透性 |

| Abstract: | Under water stress,the relative water content and chlorophyl content were reduced but relative permeability of membrances was increased of the seedling of Ailanthus altissima.The effect on these physiological indexes of water stress was aggravated along with the prolonging of water stress time.The result also showed that the resistance of different aged seedlings was not same.Relative permeability of membrances,the relative water content and chlorophyl content could be used as appraising water-resistance indexes for the seedling of Ailanthus altissima. |
| Keywords: | Ailanthus altissima Drought-resistance Relative permeability of membrances WSD |
