| 摘 要： | 油蒿是鄂尔多斯高原南部毛乌素沙地的重要固沙植物和荒漠草原优势植物,本试验系统研究了AM真菌对油蒿生长和抗旱性的影响。结果表明:接种AM真菌促进了油蒿生长,改善了油蒿叶片水分状况,增强了叶片细胞质膜的稳定性,使可溶性糖和叶绿素含量增加,叶片保护系统(可溶性蛋白含量、POD活性、CAT活性)功能增强,但脯氨酸含量和SOD活性降低。

| Abstract: | Artemisia ordosica is important sand-fixing plants and desert-steppe predominant plants in Mu Us of south of Ordos plateau.This test researched the effects of AM fungi on the growth and drought-resistance of Artemisia ordosica.The results showed: After inoculating the AM fungi,the growth of Artemisia ordosica plant was promoted,moisture conditions of leaves was improved,stability of leaves cell membrane was strengthened,content of soluble sugar and chlorophyll increased,function of leaves protective and defense system(content of soluble protein,activities of POD and CAT)was enhanced,but Pro content and SOD activity decreased.This research provides the theory basis for the application of AM biotechnology in the desert vegetation restoration and ecology reconstruction. |
