Study on the drought-resistant identification indexes in maize

The drought resistant coefficient，proline content，leaf water potential，MDA content，relative conductivity，evaporate ratio，leaf areas and the change of leaf morphology can all be used as well parameters for drought-resistant identification indexes in maize．At the same time．the correlation coefficients between drought-resistant coefficient and physiological and biochemical indexes are calculated so as to evaluate the importance for those indexes in drought-resistant identification and to analysis comprehensively．
