Abstract

The current study focuses on yield and nutritional quality changes of wheat grain over the last 166 years. It is based on wheat grain quality analyses carried out on samples collected between 1850 and 2016. Samples were obtained from the Broadbalk Continuous Wheat Experiment (UK) and from herbaria from 16 different countries around the world. Our study showed that, together with an increase in carbohydrate content, an impoverishment of mineral composition and protein content occurred. The imbalance in carbohydrate/protein content was specially marked after the 1960's, coinciding with strong increases in ambient [CO] and temperature and the introduction of progressively shorter straw varieties. The implications of altered crop physiology are discussed.

摘要

本研究聚焦于过去 166 年来小麦籽粒的产量和营养品质变化。该研究基于对 1850 年至 2016 年间采集的样本进行的小麦籽粒质量分析。样本来自英国的 Broadbalk 持续小麦试验和来自全球 16 个不同国家的标本馆。我们的研究表明，随着碳水化合物含量的增加，矿物质组成和蛋白质含量的减少。这种碳水化合物/蛋白质含量的不平衡在 20 世纪 60 年代以后特别明显，当时大气 [CO] 和温度大幅上升，同时逐渐引入了秸秆更短的品种。本文讨论了作物生理学改变所带来的影响。
