摘 要 研究了不同基因型亚麻形态发生过程中可溶性糖、可溶性蛋白、核酸等内容物及抗氧化物酶CAT、SOD和POD酶活性变化，探讨其形态发生过程生理生化变化规律。结果表明，在两个品种亚麻各阶段中，胚性愈伤中的CAT、POD、可溶性蛋白、核酸和可溶性糖含量均高于非胚性愈伤组织，这些物质含量和组分的变化与胚性的维持和细胞的旺盛分裂分化有关，而SOD在无菌苗和不定芽期含量高，初始愈伤组织中的含量是最低的，与其抗氧化能力密切相关。

Abstract In order to explore the physiological and biochemical change law during morphogenesis process of flax, some matters like soluble sugar, soluble protein, nucleic acid, etc. and activity changes of anti-oxidation enzymes CAT, SOD and POD during the morphogenesis process of flax in different genotypes were studied. The results showed that in each stage of the two flax varieties, contents of CAT, POD, soluble protein, nucleic acid and soluble sugar in embryogenic callus were all higher than those in non-embryogenic callus, furthermore changes in contents and components of above matters were related to the embryogenic maintenance and the vigorous segmentation and differentiation of cell; While the content of SOD was high in aseptic seedlings and adventitious buds, but lowest in initial callus, which was closely related to the antioxidant capacity of SOD.
