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。

Abstract: 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 , tran2 spiration rate and WUE compared with the control .
