| 摘 要： | 以在新疆准噶尔盆地南缘自然荒漠区、自然人工交错带、人工种植区等3种不同生境类型下的梭梭(Haloxylon ammodendron(C.A.Mey.)Bge)和柽柳(Tamarix ramosissima Ldb)为研究对象,测定植物叶片的丙二醛(MDA)含量及超氧化物歧化酶(SOD)、过氧化物酶(POD)、过氧化氢酶(CAT)3种保护酶活性,研究不同生境下梭梭和柽柳的生理生态特性,为准噶尔盆地南缘植被的恢复与重建提供理论依据。结果表明,自然荒漠区和人工种植区的柽柳和梭梭丙二醛含量较多,保护酶活性较高。而自然人工交错带上的植株相对于上述2种样地,丙二醛含量和保护酶活性都较低。结合野外调查和数据分析表明梭梭比柽柳具有更强的耐旱性。

| Abstract: | The natural desert region,the natural artificial ecotone and the cultivated area are the three different habitats of Tamarix ramosissima and Haloxylon ammodendron distributed on the southern edge of Zhunger Basin in Xinjiang Uygur Autonomous Region.This paper studied the physiological and ecological characteristics of Haloxylon ammodendron and Tamarix ramosissima from the content of MDA and activity of SOD,CAT and POD,and offered the theory gist on the renewal and reconstruction of vegetation on the souther... |
