摘要:The study utilized six maize hybrids as materials and different NaCl concentrations solutions to simulate salt stress environment, researching the trait differences of maize germination, specifically including plant height, leaf fresh weight, root fresh weight, leaf dry weight, root dry weight, leaf moisture content, moisture content root, root to shoot ratio, germination rate etc. It also explored the correlation between different NaCl solution concentration and the each trait of maize germination.The results showed that the trait differences of the different hybrid combinations reached the level of 0.05 or 0.01 except the leaf moisture content and root moisture content at germination stage. As a result , these indexes can be used as indicators of the salt tolerance maize about screening, identification . NaCl concentration was significantly correlated with each trait, excluding root shoot ratio Increases with increasing of NaCl concentration, the other indicators decreased with the increasing of NaCl concentration.%以6个玉米杂交组合为材料,通过不同浓度的NaCl溶液模拟盐胁迫环境,研究玉米萌芽期的株高、茎叶鲜重、根鲜重、茎叶干重、根干重、茎叶含水率、根含水率、根冠比、发芽率等性状的差异,并探讨了不同NaCl溶液浓度与玉米萌芽期各性状的相关关系.结果表明:不同杂交组合萌发期各性状除茎叶含水率和根含水率外,其余性状差异达到了显著或极显著水平,因此这些指标都可作为耐盐玉米种质筛选、鉴定标准.NaCl浓度与各性状都呈极显著相关,除根冠比随NaCl浓度升高而增加外,其他指标都随NaCl浓度升高而降低.
