Tetraena mongolica Maxim. is an endemic species of plant to InnerMongolia, first-grade protected plant by Inner Mongolia AutonomousRegion and second-grade by China. This paper has first reported the waterconditions and water metabolism characteristics of the plant, concretely,total water contents, free water contents and bound water contents, aswell as water potentials, transpiration rates and dehydration resistances.Additionally, the relation between the water metabolism and droughtendurances has been discussed. The results of the work will provids ascientific basis for protecting the rars and precious plant for the future.
