[目的]测定四翅滨藜的抗旱生理指标,并与新疆较典型抗旱植物进行比较,为其大面积推广提供理论基础.[方法]通过PEG_(6000)对新疆地区比较典型的10种抗旱植物进行胁迫处理,分别测定处理前后10种植物体内脯氨酸、根活力(TTC含量)、丙二醛、可溶性糖、可溶性蛋白、超氧化物歧化酶和过氧化氢酶的含量,同时比较胁迫处理前后的变化量,并且对四翅滨藜以上生理指标进行定性和定量的分析.[结果]四翅滨藜与其它9种植物比较,植物体内脯氨酸、TTC和过氧化氢酶含量及处理前后的增加量均最高;丙二醛含量及处理前后的增加量最低;可溶性糖和可溶性蛋白含量及处理前后增加量均处于第二位.[结论]在10种植物中,四翅滨藜对干旱的抵御协调能力最强.

[Objective and Method]The objectives of this study were to reveal the ten plants′ content of proline, TTC, MDA, soluble sugar, soluble protein, SOD, POD before and after stress treatments and were to compare their changes and analyze the physiological indexes of Atriplex canescens and other drought-resistant plants quatitatively and qualitatively.[Result]The results showed the content of proline of Atriplex canescens was the highest compared with that of other 9 kinds of plants.The plant in content of MDA was the lowest before and after stress treatments.The content of soluble sugar and soluble protein was in second before and after stress treatment. [Conclusion]It can clearly be seen,Atriplex canescens had the strongest drought-resistance compared with that of other plants.
