The cultivation area of soybean (Glycine max (L.) Merr) is increasing in Germany as a way to ensure self-sufficiency through its use as feed and food. However, climatic conditions needed for soybean cultivation are not appropriate in all parts of the country. The objective of this study was to determine the influence of solar radiation, temperature, and precipitation on soybean seed productivity and quality in central and south Germany. A multi-factorial field trial was carried out with three replicates at four locations in 2016 and five locations in 2017, testing 13 soybean varieties from the maturity groups MG 00 and MG 000. Considering all the tested factors, “variety” was highly significant concerning protein content (Ø 41.1% dry matter (DM)) and oil content (Ø 19.1% in DM), but not seed yield (Ø 40.5 dt ha−1).The broad sense heritability of protein content was H2 = 0.80 and of oil content H2 = 0.7. Protein and oil content were significantly negatively correlated (r = −0.82). Seed yield was significantly positively correlated with solar radiation (r = 0.32) and precipitation (r = 0.33), but significantly negatively with Crop Heat Units (CHU) (r = −0.42). Over both experimental years, varieties from maturity group MG 00 were less significantly correlated with the tested environmental factors than varieties from maturity group MG 000. None of the environmental factors tested significantly increased the protein or oil content of soybean. In growing areas with heat periods during ripening, protein content tended to be higher than in cooler areas; in areas with high solar radiation during flowering, protein content tended to be reduced.

环境对德国中部和南部大豆(Glycine Max(L.)Merr)生产的影响

大豆的种植面积(大豆(L.)Merr)在德国正在增加,以通过将其用作饲料和食品来确保自给自足。但是,大豆种植所需的气候条件并不适合该国所有地区。这项研究的目的是确定太阳辐射,温度和降水量对德国中部和南部大豆种子的生产率和品质的影响。一项多因素田间试验在2016年的四个地点和2017年的五个地点进行了三个重复试验,测试了成熟度组MG 00和MG 000的13个大豆品种。考虑到所有测试因素,“品种”对于蛋白质含量(Ø41.1%干物质(DM))和油脂含量(Ø19.1%,以DM计),但不包括种子产量(Ø40.5 dt ha -1)蛋白质含量的广义遗传力为H 2 = 0.80和油含量为H 2= 0.7。蛋白质和油含量显着负相关(r = -0.82)。种子产量与太阳辐射(r = 0.32)和降水(r = 0.33)显着正相关,而与作物热量单位(CHU)则显着负相关(r = -0.42)。在两个实验年中,成熟度组MG 00的品种与被测环境因子的相关性均不及成熟度组MG 000的品种相关。被测环境因子均未显着增加大豆的蛋白质或油含量。在成熟期间处于高温时期的生长地区,蛋白质含量往往高于凉爽地区。在开花期间太阳辐射高的地区,蛋白质含量往往会降低。
