Abstract: The study with pot experiment showed that under light(30%-35%)and medium(45% -50%) soil water stress, Elaeagnus mollis seedlings leaves had a smaller decrease of water and chlorophyll contents, higher water potential, and lower MDA content. The seedlings could grow normally, and presented the typical physiological characters of drought-resistant plant. Under serious (20%-25%) soil water stress, the water and chlorophyll contents in E. mollis seedlings leaves decreased markedly,water potential was the smallest,MDA content reached the highest,and the seedlings were short and colored yellow,suggesting that the seedlings were significantly harmed by the drought stress and couldn’t grow normally.
