Using 3 different Chinese cabbages as experiment material in rosette stage, the effect of drought stress on physiological and biochemical characteristics of Chinese cabbages was studied, and the drought resistance of different Chinese cabbages was evaluated by subordinate function. The re- sult showed that, with the increase of drought stress, leave relative water content, chlonophy cont- ent and net photosynthetic rate decreased, while the cell membrane permeation, MDA content, sol- uble sugar content and proline content increased. The drought resistance in 3 different Chinese cab- bages was variable, and the ＇Xinzao 56＇ had higher drought resistance, followed by ＇Xinxiang xiaobao＇ and ＇Beijing xiaoza＇.
