四翅滨藜耐盐生理的研究

新疆是中国的荒漠化大区之一，也是中国最大的盐土区，而这一特殊环境的植被可以作为重要的植物资源。在众多植物品种中，有哪些品种能适应新疆的盐渍化环境，适应能力如何，探明这些问题将对新疆生态环境的改善，品种资源的充分利用，经济的发展都有较大的影响。选用干旱半干旱盐渍地区典型的10种植被，通过不同浓度NaCl溶液对其进行盐胁迫处理，其中，四翅滨藜在用2.1%NaCl溶液胁迫复水后, 幼株能正常生长。分别测定处理前后10种植物体内脯氨酸、根活力、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2~3]。结果表明：四翅滨藜是优良的耐盐植物品种。

Study on Physiology of Resist Salt of Atriplex Canescens

Xinjiang is the biggest desert and salt area in China, where the plants are considered as the important plant resources. In lots of plants， which varieties can adapt, how are the capability，which problems influence on improving Xinjiang′s ecological environments﹑using resources of varieties﹑developping economy. Ten topical plants are choosed in drought and half-drought areas, which are induced by different concentration NaCl solution, in which Atriplex canescens grows normally after inducing by 2.1% NaCl solution and returning by water. Ten topical plants resisting drought in Xinjiang are induced by PEG6000.Ten plants′content of praline﹑TTC﹑MDA﹑soluble sugar﹑soluble protein﹑SOD﹑POD are identified before and after inducing, changes are compared.The results show: Atriplex canescens is the best plant resisting salt in above topical plants.
