摘要: 【目的】研究非生物胁迫对不同玉米杂交种苗期生长的影响,比较其适应非生物胁迫的能力,为玉米杂交种的生产提供参考依据。【方法】以3种玉米杂交种新玉47号、九玉J03、九圣禾2468为材料,分别用PEG 6000、NaCl、低温、强光胁迫处理一周后,测定3种杂交种幼苗株高、茎粗、叶面积等各种生长指标。【结果】不同非生物胁迫对玉米幼苗株高、茎粗、叶面积、相对含水量等均有不同程度的抑制作用,3种玉米品种的抗逆性表现各不相同。九玉J03适应盐和低温的能力较强;九圣禾2468适应旱、强光的能力较强;而新玉47号在这些非生物胁迫下均表现一般。【结论】3个不同地区种植的玉米杂交种对环境的适应能力各不相同。

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.
