Abstract: 6 rice cultivars with different drought tolerance were used to study the changes of morphological and physiological indexes of rice during germinating stage under osmotic stress. The results showed the drought-resistant coefficient was significantly (or very significantly) correlated with the relative length of coleoptiles and radicles, relative activities of superoxide dismutase (SOD), catalase (CAT), peroxidase (POD) and relative contents of reduced glutathione (GSH), proline (Pro), vitamin C (Vc), malondialdehyde (MDA), spermidine (Spd) and spermine (Spm), which therefore could be used as the evaluation indexes of drought tolerance at germinating stage. The integrated drought resistance indexes including the relative contents of Vc, GSH and Spm were established by principal components analysis. The drought resistance of 6 rice cultivars was evaluated by regression equation and was basically consistent with the results from paddy field, proving it is effective to predict the drought resistance during germinating stage in rice using the integrated identification index screened out in this study
