To study the effect of drought stress on the growth of Glycyrrhiza uralensis and its drought resistance characteristic.The growth in dicators of G. uralensis including leaf, stem, root and biomass were measured when two-years-old G. uralensis had lived in drought stress soil for 60 days.The growth of all organs of G. uralensis was restrained because of drought stress, especially to up ground organs.It is obvious that the restraining effect of drought stress on G. uralensis possesses organ speciality. Both yield and quality of G. uralensis will be satisfied when it grows in the soil with relative water content of 50%.
