中文摘要	【目的】本文探究了干旱胁迫对新疆南疆干旱区园林树种的影响,以期为干旱区抗旱性树种的选择提供依据.【方法】采用盆栽试验控制水分胁迫时间,以新疆杨( Populus alba) ,大叶白蜡( Fraxinus rhynchophylla) ,夏橡( Quercus robur) ,文冠果( Xanthoceras sorbifolium)和黑核桃( Jugiqns nigra)为试验材料,分析自然干旱胁迫条件下5个树种的保护酶及渗透调节物质的变化趋势及抗旱性.【结果】随着干旱胁迫时间的持续,5个树种的可溶性蛋白含量和保护酶活性呈升高趋势,其中新疆杨酶活性增加最为显著,文冠果酶活性变化幅度较小; 5个树种的MDA含量及脯氨酸含量随着干旱胁迫时间的持续而呈上升趋势,并且脯氨酸含量呈显著上升.【结论】隶属函数法评价的结果为:不同干旱胁迫环境下,5个树种的抗旱能力表现依次:文冠果>新疆杨=白蜡>黑核桃>夏橡.
英文摘要	【Objective】The present paper aimed to study the effect of drought stress on the garden trees in arid area of southern Xinjiang to provide a basis for drought resistance selection of garden trees.【Method】Taken five species of Populus alba,Fraxinus rhynchophylla,Quercus robur,Xanthoceras sorbifolium and Jugiqns nigra as tested materials,the pot experiments were conducted,the comparisons of five tree species of protective enzymes and osmotic adjustment substances in the trend under drought conditions were made.【Result】The soluble protein content and protective enzyme activities of the five tree species increased with the drought stress duration,of which the activity of the Populus alba tree was the most significant,and the activity of the activity of the Xanthoceras sorbifolium tree was smaller. Their MDA contents and proline contents increased with the duration of drought stress,and the content of proline was significantly changed. 【Conclusion】 Through membership function comprehensive evaluation and analysis,the drought tolerance of 5 tree species from high to low were : Xanthoceras sorbifolium > Populus alba = Fraxinus rhynchophylla > Jugiqns nigra > Quercus robur.
