| 摘 要： | 以聚乙二醇（PEG-6000）的渗透溶液模拟水分胁迫条件，比较了不同水分胁迫强度下3种相思幼苗的抗旱性，并确定了鉴定幼苗抗旱性的生理指标。结果表明：相对电导率、相对含水量、相对水分亏缺、可溶性糖含量、游离脯氨酸等指标可作为鉴定相思幼苗早期抗旱性的生理指标；3个树种的抗旱能力排序为：厚荚相思〉大叶相思〉马占相思。 |

| Abstract: | This paper compared the drought resistance of three seedlings of Acacia under different water stress by means of treating with polyethylene glycol 6000 (PEG-6000) solutions with different osmotic potentials to imitate the condition of water stress , furthermore, decided appraising physiological indexes of early drought resistance of seedlings. The result showed that the indexes of EC, RWC, RWD, Ssug and Fpro could be used as appraising indexes of early drought resistance of seedlings of Acacia, and concluded that the drought resistance of three tree species from strong to weak was A. crassicarpa, A. auriculaeformis, A. mangium. |
| Keywords: | Acacia seedlings drought resistance physiological indexes |
