Effects of AM Fungi on Alfalfa Growth and Drought Resistance Under Water Stress

2014 
Taking Glomus hosseae as microbial inoculum,taking alfalfa as reseach object,the effects of AM fungi on alfalfa growth and drought resistance were studied by pot experiment under different water conditions.The results showed that when the soil relative water content was 40%,the plant leaf relative water content,proline content and soluble sugar content increased significantly after the vaccination of AM fungi,the cell membrane permeability,MDA content and three kinds of protective enzyme activities decreased obviously.Inoculation of AM fungi could promote the accumulation of plant cell osmotic regulation substances content,reduced the super oxygen free radicals,reduced the damage to the plant water stress,prompting them to better adapt to mining area drought environment.
