The drought resistance of six Glycyrrhiza uralensis Fisch.accessions from different regions was studied under simulated drought stress with PEG6000.Through measurating morphological and physiological indexes related to drought resistance,and evaluating integrative with subordinate function and system cluster analysis,we could conclude that No.1 and No.2 accessions from central region of Inner Mongolia had higher drought resistance,then followed by No.4 from eastern region of Inner Mongolia as well as No.5 and No.6 from Xinjiang.The resistance of No.3 was the lowest.Through subordinate function and system cluster analysis,20% PEG6000 was suitable for evaluation of drought resistance of licorice in germination stage.
