　　以高油115和正大619为实验材料，分别通过盆栽和田间试验研究接种摩西球囊霉和地表球囊霉对玉米根系形态和根系内源生长素含量的影响。结果表明，玉米形成菌根后根系形态明显改变，根条数显著多于对照，并且接种处理与对照间的差异随菌根侵染率的上升而加大，差异极显著。生长60 d时，有菌根的玉米单株总根长度为788.61 cm，根系重量达8.26 g，均显著高于无菌根的对照。根系生长素含量随菌根侵染率上升而增加，并且显著高于不接种的对照。丛枝菌根真菌侵染可以促使玉米根内生长素含量上升，根条数增多，增加吸收面积，促进玉米生长。

Maize cultivar GY115 and ZD619 were used for experimental materials cultured in pot and field re-spectively.The effects of Glomus mosseae and G. versiforme on root morphology and root endogenous growth hormone content of maize(Zea mays) were studied. The results showed that the morphology of mycorrhizal maize roots signifi-cantly changed, root number increased after mycorrhization. Furthermore, the difference between mycorrhizal and non-mycorrhizal roots increased with the development of mycorrhizal infection rate. When grew 60 days, mycorrhizal maize total root length per plant of 788.61 cm, fresh root weight per plant of 8.26 g, were significantly higher than non-mycorrhizal root. Growth hormone content in roots increased with mycorrhizal infection rate increasing, and the content of IAA in inoculation treatment was higher than control significantly. This study indicated that AM fungi can induce the growth hormone content increased in maize roots, enhance root number, and thereby increase the root sur-face of nutrient absorption to improve plant growth.
