Abstract: 【Objective】 To explore the adaptability to abiotic stresses, the morphological indexes of three maize hybrids (Xin Yu 47, Jiu Yu J03 and Jiu Sheng He 2468) were measured. 【Methods】 After the hybrids were treated with PEG 6000 for one week, NaCl, low temperature and higher illumination, morphological indexes including plant height, stem diameter, leaf area etc. were analyzed. 【Results】 Different abiotic stresses had different inhibitory effects on plant height, stem diameter, leaf area and relative water content of maize seedlings and the tolerance of three maize varieties was distinct. For example, Jiuyu J03 had a strong ability to adapt to salt and low temperature, Jiushenghe 2468 had a strong ability to adapt to drought and strong light, while Xinyu 47 behaved just so-so under these abiotic stresses. 【Conclusion】 In this study, maize hybrids planted in three different regions had different adaptability to the environment, which might be used as reference for the production of maize hybrids in the early developmental stage.
