摘　　要：丛枝菌根可在与植物共生的过程中增加植物对营养元素的吸收 ,增加植物的生长量 ,提高植物的抗旱抗涝性。在盆栽条件下 ,水分控制在 10 %左右时 ,接菌的小麦和对照相比降低了气孔的阻力 ,提高了叶片气孔传导力 ,蒸腾速率 ,有效光合作用和水平利用效率。Drought is a major restriction to plant growth. AMF(arbuscular mycorrhizal fungi)can increase the absorption of nutrition, facilitate the growth of plant and improve drought resistance of many plants. The experiment compared the effects of two AMF species on wheat at 10% water level. The wheat inoculated with 90089 and 90036 decreased stomatal resistance, increased net photosynthetic rate, stomatal conduction,transpiration rate and WUE compared with the control.
