测定了25个安第斯马铃薯品种(Solanum tuberosum L.)块茎中抗坏血酸(AA)的含量。在三种环境中生长，并评估烹饪和储存时间对样品子集的影响。由于基因、环境和基因×环境-环境(G×E)交互作用的影响，存在显著差异。新鲜采收生、去皮块茎中的AA含量在22.2-121.4 mg/100g(干重)和6.5-36.9 mg/100g(FW)之间，加入704393表明AA在所有三个地点的最高水平。不同烹调方法和贮藏时间对AA浓度的影响不同，且这两个参数与基因型之间存在显著的非交叉互作效应。结果表明，6个供试品种块茎中AA含量均高于烘箱和微波处理，23个品种的AA含量随贮藏时间的延长而降低。品种704393在农家条件下煮沸贮藏26周后，AA含量分别保持54%和34%。百克新鲜收获的这个品种的煮土豆(704393)可以为成年人提供推荐的每日AA摄入量的17-20%。(C)2008 Elsevier Inc.保留所有权利。
The ascorbic acid (AA) concentration Of tubers was determined in 25 Andean potato varieties (Solanum tuberosum L.) grown in three environments, and the effect of cooking and storage time in subsets of samples was evaluated. Significant variation due to genotype, environment and genotype x environ-environment (G x E) interaction was found. AA concentration in freshly harvested raw, peeled tubers ranged from 22.2 to 121.4 mg/100 g on a dry weight basis (DW) and from 6.5 to 36.9 mg/100 g on a fresh weight basis (FW) with the accession 704393 showing the highest levels of AA in all three locations. Differences in AA concentration were found among cooking methods and storage times; and significant non-crossover interactions with genotype were observed for both of these parameters. It was found that AA concentration of boiled tubers of the six varieties evaluated was higher than in oven and microwaved tubers and that AA concentration Of tubers of the 23 varieties evaluated decreased with storage time. The variety 704393 retained 54 and 34% of its original AA concentration after boiling and storage during 26 weeks under farmer conditions. One hundred grams of fresh harvested boiled potatoes of this variety (704393) could provide adults with 17-20% of the recommended daily allowance (RDA) of AA. (C) 2008 Elsevier Inc.
