甘肃连城自然保护区4种云杉属植物种子可溶性蛋白的差异研究

Study on Differences of Soluble Protein of 4 Picea Species' Seeds in Liancheng National Nature Reserve in Gansu

利用SDS-聚丙烯酰胺凝胶电泳法对连城国家级自然保护区4种云杉属植物进行了种子蛋白谱带分析,以利对该区分类地位不明确的麻衣松进行分类地位的确定.结果表明,黑青杄和白青杄的谱带相似,谱带颜色较浅,二者与麻衣松的不相似值较大,分别为8.33和6.12;麻衣松和青海云杉谱带非常相似,谱带颜色深,不相似值为1.96,由此认为麻衣松可能是青海云杉的种内类型.

We analyzed the band of seed protein of 4 Picea plants in Liancheng national nature reserve in Gansu by using SDS-PAGE, in order to define the classification of Mayisong whose systematic status was unclear. The result showed that the bands of Heiqingqian and Baiqingqian were similar and their bands＇ colors were light; their dissimilar-value and Mayisong＇ s were bigger, namely 8.33 and 6. 12. But the bands of Mayisong and Picea carassifolia were very similar with dark color, their dissimilar-value was 1.96. Therefore, we concluded that Mayisong was intraspecific category of Picea carassifolia.
