The aim was to study the relationship between maize roots and water use efficiency and analyze the change of the morphological and physiological characteristics of regenerative plants of hairy root cultures in maize under water stress. The results reveal that the regenerative type maize with a large root system may be able to efficiently conserve water in case of drought stress, whereas the physiological studies from the measurement of leaf osmotic  and water potential show the regenerative lines posses an enhanced drought tolerance. Thus, the high root lines of the regenerative plants can keep strong hydraulic root signal and water use efficiency under water stress.
