摘　　要：丛枝菌根真菌(Arbuscular mycorrhizal fungi,AMF)作为生物方法来防治土传病害和提高植物的抗逆性具有广泛的潜力。本研究采用两种丛枝菌根真菌(AMF)Glomus mosseae和Glomus etunicatum对棉花黄萎病感染植株进行接种处理,建立AMF接种应用的基础技术参数。结果表明,接种植株根系的苯丙氨酸解氨酶(PAL)、几丁质酶和过氧化物酶(POD)活性得到了提高,酚类物质、可溶性糖和脯氨酸含量增加,丙二醛含量降低,AMF提高了植株的抗病性。Arbuscular mycorrhizal fungi（AMF）is a potential microbial resource for its application in the biocontrol of soil-bome diseases and the enhancement plant stress resistance enhancement.In this paper,two kinds of AMF Glomus mosseae and Glomus etunicatum are used to inoculate the infected plants by chlorosis,and the basic technical parameters of AMF inoculation are established.The results shows that AMF inoculation improves of the contents and activities of defensive enzymes in root including phenylalanine ammonialyase（PAL）,chitinase,peroxidase（POD）.AMF inoculation could also increase the contents of total phenol,soluble sugar and proline in root,and decrease the content of malondialdehyde（MDA）in root,which indicates that AMF can improve the plant disease resistance.
