【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,transpiration rate and WUE compared with the control.更多还原
