以福建省的栽培坛紫菜6、0Co-γ射线辐照的突变体为材料,分析研究了它们的蛋白质、叶绿素、藻胆蛋白、游离氨基酸含量之间的差异。分析结果表明:在相同的海况条件下,突变品系NY3显著高于当地的栽培品系GL1和LPZ;所有的突变体的叶绿素含量低于栽培坛紫菜GL1;3个突变体的总藻胆蛋白含量高于栽培坛紫菜,2个突变体的游离氨基酸含量高于栽培坛紫菜。研究结果说明坛紫菜突变体之间种质的差异是很大的,这种种质之间的差异为坛紫菜优良品种选育提供了丰富的资源。In this thesis,the amount content of proteins,chlorophyll,phycobiliprotein and free amino acids are analyzed from cultured Porphyra haitanensis in Fujian province,as well as the mutants by ~(60)Co-γ ray.The analysis results show that the mutant NY3 is notably higher than the local cultured strains GL1 and LPZ.The content of chlorophyll of all of mutant samples are lower than the cultured strain GL1.Three of the mutant samples are higher than the cultured samples.The content of free amino acids of two of mutant samples are higher than the cultured samples.The results indicate that there are great difference among the Porphyra haitanensis mutant in quality,which could offer abundant resources for strain breeding.国家海洋863项目(2002A603023
