摘要:

【目的】鉴定与评价小麦近缘种芽期和苗期的耐盐性。【方法】选用38份(含对照)小麦近缘材料,设芽期、苗期盐胁迫处理,鉴定与评价适宜的芽期和苗期耐盐性NaCl浓度,分析小麦近材料芽期、苗期耐盐性鉴定的NaCl溶液浓度分别为1.2%和1.5%。【结果】获得芽期高耐盐材料21份(占55.2%),耐盐材料8份(占21%),中耐盐材料3份(占7.8%),敏感材料4份(占10.5%),高敏材料2份(占5.2%);苗期耐盐材料7份(占18.4%),中耐盐材料17份(占44.7%),敏感材料12份(占31.5%),高敏材料2份(5.2%);成活率与成苗率均为100%的材料有2份。耐盐材料有7份,敏感材料有4份,成活率与成苗率100%的材料有2份。【结论】不同耐盐类型的材料在芽期和苗期耐盐性不一致,部分材料没有可比性,差异较大。

Abstract:

【Objective】 Identification and evaluation of salt tolerance in wheat relatives at germination and seedling stages.【Methods】 In this study, 38 wild relatives of wheat (including controls) were treated at bud and seedling stages.Wheat related species were used as experimental materials and the suitable NaCl concentrations of both 1.2% and 1.5% for salt tolerance identification and evaluation at bud and seedling stage was selected.【Results】 21materials with high salt tolerance at bud stage were obtained(55.2%), accounting for 8 salt-resistant materials(21%) and 3 medium salt-tolerant materials(7.8%);4 for sensitive materials(10.5%),2 for high sensitive(5.2%).7 materials with salt tolerance at seedling stage were obtained(18.4%), 17.medium salt-tolerant materials(44.7%),12 for sensitive materials(31.5%), 2 for high sensitive(5.2%); 2 materials with 100% at the survival rate and seedling rate.At the same time, we also found the same salt-tolerant materials at the bud and seedling stage, including 7 salt-tolerant materials and 4 sensitive materials, and found the survival rate and seedling rate of 100% at both stages for 2 materials.【Conclusion】 The analysis showed that the salt resistance of different salt tolerant types is not consistent in bud stage and seedling stage, and some materials are not comparable and have great differences.But they all have their own significance in the salt-tolerant germplasm screening.

Key words: wheat related materials; bud and seedling stage; screening; identification and evaluation of salt tolerance
