蛋白质在二倍体马铃薯中的分布及相关性分析

Distribution of Protein Content in Diploid Potato Plants and Their Relations

马铃薯蛋白质具有丰富的营养价值。以9个二倍体马铃薯品系(Solanum phureja-S.stenotomum杂种)为试验材料,采用盆栽的方式研究蛋白质在茎、叶、块茎中的分布及相关性。结果表明:以干、鲜重为基础的叶片蛋白质含量都极显著高于块茎和茎秆,茎秆含量最低;以干重为基础时,叶片与茎秆蛋白质含量呈极显著正相关,以鲜重为基础时,叶片与块茎和茎秆蛋白质含量都呈极显著正相关。

Potato protein is well known for its nutrition value. In this research, 9 diploid potato clones （Solarium phureja-S, stenotomum hybrids）, which were grown in pots, were investigated for distribution of the protein in stems, leaves and tubers, and their relations. The protein content in leaves was high significantly higher than that in tuber and stem, with stems having lowest level of protein, on the basis of both fresh and dry weight. When the protein percentage significantly correlated to the was expressed on the basis protein in stems. It was high of dry weight, the protein content in leaves was high significantly correlated to proteins in both stems and tubers when expressed on fresh weight.
