摘　　要：旨在为筛选、培育耐盐的纤维亚麻突变体奠定前期基础。NaCl胁迫亚麻幼苗,测定幼苗的叶绿素组成及含量、脯氨酸、可溶性糖、可溶性蛋白和甜菜碱含量,经统计学分析和比较,确定它们的耐盐特性。结果表明,经250mmol/LNaCl胁迫后,HIZ019和‘天鑫3号’幼苗的脯氨酸含量显著高于其他品种;YOI303和YOI254幼苗的可溶性糖含量显著高于其他品种;YOI254幼苗的可溶性蛋白含量显著高于其他品种;HIZ019、‘天鑫3号’幼苗的甜菜碱含量显著高于其他品种。总体上看,YOI254、‘天鑫3号’和HIZ019纤维亚麻幼苗耐盐性较好。The aim was to lay the preliminary foundation for screen and breed somatic salt tolerant mutants of flax. Seedlings were stressed with NaC1 （0, 100, 150, 250 mmol/L）, biochemical characteristics （composition and content of chlorophylls, proline, soluble sugar, soluble protein, betain contents） of the seedling were detected; their salt tolerances were determined by data analysis and comparison. From biochemical characteristics of the seedlings, after treated with 250 mmol/L NaC1, proline contents of HIZ019 and ＇Tianxin 3＇ were significantly higher than that of others. Soluble sugar contents of YOI303 and YOI254 were significantly higher than that of others. Soluble protein content of YOI254 was significantly higher than that of others. Betain contents of HIZ019 and ＇Tianxin3＇ were significantly higher than that of others. In a word, flax seedlings of YOI254, ＇ Tianxin3＇, HIZ019 species were more salt tolerant than that of others.
