束状球囊霉以连翘（Forsythia suspensa（Thunb.）研究了丛枝菌根真菌对小麦抗旱性的影响，结果表明：丛枝菌根真菌能提高小麦叶片叶绿素含量、游离脯氨酸含量、SOD活性，在干旱胁迫下，随着侵染率的增加，MDA含量和膜损伤程度降低，幼苗死亡率降低，说明菌根真菌能够增强幼苗的抗干旱能力，在干旱胁迫下，通过迅速积累游离脯氨酸，提高SOD活性，延缓细胞膜伤害程度，增强幼苗的抗旱性，从而达到缓解幼苗干旱的目的，不同接种方式中，以混合接种效果最好，其次为缢管线虫。
Glomus fasciculatum Gerd. Trappe emend.Walker and Koske,Glomus constrictum Trappe were separately and/or mixed inoculated on seeding of Forsythia suspensa(Thunb.)Vahl.The effects of arbuscular mycorrhizal fungi on drought resistance were studied in this paper.The results showed the content of chlorophyl and free proline were increased,the activity of SOD was enhanced,MDA and damage of membranes were decreased and the rate of seedling death was reduced with the adding of infection rate when F.suspensa suffered from drought.It indicated that mycorrhizal fungi can strengthen the anti-drought of the seeding by cumulating rapidly free proline and enhancing quickly the activity of SOD,deferring the harmful degree of cell membranes,strengthening the drought resistance of the seeding in the stress of drought.Among different manner of inoculation,mixed inoculation was the best and G.constrictum was second.
