摘要:: 利用盆栽试验在正常水分和干旱胁迫条件下研究了非灭菌土接种AM真菌摩西球囊霉（Glomus mosseae）和土著AM真菌（Indigenous arbuscular mycorrhizal fungi）对油蒿（Artemisia ordosica）生长及抗旱性的影响。结果表明：干旱胁迫显著抑制了AM真菌对油蒿的侵染。无论在正常水分还是干旱胁迫条件下，接种AM真菌都增加了植株的分枝数、地上部鲜重和干重、地下部鲜重和干重，但没有明显提高株高、茎粗和改善组织水分状况；与未接种相比，干旱胁迫下接种土著AM真菌显著提高了根系氮、磷含量，提高了叶绿素、可溶性蛋白含量，增强了保护酶超氧化物歧化酶（SOD）、过氧化物酶（POD）、过氧化氢酶（CAT）的活性并降低了丙二醛的含量，因此增强了植物的抗旱性。

Abstract:: The effects of arbuscular mycorrhizal fungi(AMF)（Glomus mosseae and the indigenous AM fungi）on growth and drought tolerance of Artemisia ordosica in unsterilized soil was studied in potted culture under well water and drought stress conditions.The results indicated that AMF colonization on A. ordosica was significantly decreased by drought stress.Branch number, plant fresh and dry weight of A. ordosica were increased by inoculation with AMF under well-watered and drought stress conditions，but height of shoots and stem diameter and plants water status were not significantly improved. Inoculation of the indigenous AMF notably improved the contents of N and P in roots when compared with non-mycorrhizal plant under drought stress, AM fungi inoculation could enhance the contents of the soluble protein,Chl of leaves,and promote the activity of superoxide dismutase (SOD),catalase (CAT),peroxidase (POD),decrease the leaf content of MDA.Thus,the ability of drought resistance of A. ordosica was promoted by inoculating the AMF.
