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250 mmol/L NaCl 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。
旨在為篩選、培育耐鹽的纖維亞痳突變體奠定前期基礎。NaCl脅迫亞痳幼苗，測定幼苗的葉綠素組成及含量、脯氨痠、可溶性糖、可溶性蛋白和甜菜堿含量，經統計學分析和比較，確定它們的耐鹽特性。結果錶明，經250 mmol/L NaCl 脅迫後，HIZ019和‘天鑫3號’幼苗的脯氨痠含量顯著高于其他品種；YOI303和YOI254幼苗的可溶性糖含量顯著高于其他品種；YOI254幼苗的可溶性蛋白含量顯著高于其他品種；HIZ019、‘天鑫3號’幼苗的甜菜堿含量顯著高于其他品種。總體上看，YOI254、‘天鑫3號’和HIZ019纖維亞痳幼苗耐鹽性較好。

The aim was to lay the preliminary foundation for screen and breed somatic salt tolerant mutants of flax. Seedlings were stressed with NaCl (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 NaCl, 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.
