气温升高和对高产地食品和饮料产品的兴趣日益增加，为北方欧洲的谷物种植创造了新的机会。然而，在这些地区种植燕麦和大麦用于制麦芽和制粉仍然是一个挑战，主要是因为天气原因，而且关于该地区燕麦和大麦营养成分的报告很少。在这项研究中，奥克尼的试验比较了推荐的英国燕麦和大麦品种与斯堪的纳维亚品种的农艺性状和营养含量超过三年。对于一个子集的品种，营养成分进行了比较，在更偏南的网站种植的样品。对奥克尼来说，大麦被认为是比燕麦更合适的作物，因为品种成熟得更早。在这两种作物中，斯堪的纳维亚品种比英国品种成熟得早，有些品种的产量相当。在奥克尼燕麦和大麦的常量营养素和矿物质的值的范围与以前报道的其他地点相似，但有一些显着的差异归因于品种和年份。与来自更南部地区的谷物样本相比，奥克尼的燕麦具有显著较低的β-葡聚糖和较高的钠含量。较低的P-葡聚糖可能是由于在灌浆和成熟的几个月里降雨量较高和温度较低造成的。皇冠版权所有（C）2017由爱思唯尔有限公司发布。保留所有权利。
Warmer temperatures and increasing interest in high provenance food and drink products are creating new opportunities for cereal growing in northern Europe. Nevertheless, cultivation of oats and barley in these areas for malting and milling remains a challenge, primarily because of the weather, and there are few reports of their nutritional content from this region. In this study, trials in Orkney compared agronomic characteristics and nutritional content of recommended UK oat and barley varieties with Scandinavian varieties over three years. For a subset of varieties, nutritional content was compared with samples cultivated in more southerly sites. For Orkney, barley was considered a more suitable crop than oats because varieties matured earlier. In both crops, Scandinavian varieties matured earlier than UK varieties and some produced comparable yields. The range of values for macronutrients and minerals in oats and barley in Orkney were similar to those reported previously for other locations, but there were some significant differences attributable to variety and year. Compared with grain samples from more southerly locations, oats in Orkney had a significantly lower beta-glucan and higher sodium content. The lower P-glucan may have resulted from higher rainfall and lower temperatures during the months of grain filling and maturation. Crown Copyright (C) 2017 Published by Elsevier Ltd.
