Abstract

The total ascorbate content of potato tubers from 33 Solanum tuberosum genotypes grown at three geographically diverse sites in Europe in each of two years was determined immediately postharvest and after approximately 4 months of storage at 4 degrees C. Statistically significant differences in total ascorbate concentration were observed between genotypes both at harvest and after storage. In all genotypes, the levels of ascorbate decreased during storage. These results are discussed in terms of their implications for diet and health as well as in terms of breeding for improved vitamin C content in potatoes.

摘要

在两年中的每一年，对种植于欧洲三个地理位置不同地点的33种马铃薯基因型的块茎，在收获后立即以及在4℃下储存约4个月后，测定其总抗坏血酸含量。在收获时和储存后，各基因型之间的总抗坏血酸浓度均存在统计学上的显著差异。在所有基因型中，抗坏血酸水平在储存期间均有所下降。本文从这些结果对饮食和健康的影响以及马铃薯中维生素C含量改良育种的角度进行了讨论。
