大豆（甘氨酸最大（L）Merr）种子含有对人类健康有积极影响的异黄酮。这项研究的目的是确定在不同环境中生长的早期成熟大豆品种的异黄酮浓度，并确定它们与其他重要种子特征的关系。 2002/2003年，在加拿大蒙特利尔的两个地点的复制试验中种植了二十种大豆品种，它们的总和伊索拉维酮浓度由高性能液相色谱法确定。同时确定种子产量，100种子的重量和油，粗蛋白和粗纤维浓度。总和异黄酮的浓度受到品种，现场和年份的显着影响。总异黄酮浓度范围为360至2241杯G（-1），跨环境和品种平均851杯G（-1）。特定品种的环境变化范围为20％至100％。 2003年，总异黄酮浓度平均高40％，其特征是温度高于平均水平和严重的干旱。尽管X年级X X网站相互作用很大，但在环境之间始终如一地识别出具有始终高和低异黄酮浓度的品种。在总异黄酮浓度和种子产量，100种子的重量和粗纤维之间观察到弱但显着的正相关，这表明异黄酮浓度与其他期望的种子特征呈正相关。 （c）2004化学工业学会。
Soybean (Glycine max (L) Merr) seeds contain isoflavones that have positive impacts on human health. The objective of this study was to determine isoflavone concentrations of early maturing soybean cultivars grown in different environments and to determine their relation to other important seed characteristics. Twenty soybean cultivars were grown in replicated trials at two sites in Montreal, Canada in 2002/2003 and their total and individual isollavone concentrations were determined by high-performance liquid chromatography. Seed yield, 100-seed weight and oil, crude protein and crude fiber concentrations were concurrently determined. Total and individual isoflavone concentrations were significantly affected by cultivar, site and year. Total isoflavone concentration ranged from 360 to 2241 mug g(-1) and averaged 851 mug g(-1) across environments and cultivars. Variation across environments ranged from 20 to 100% for specific cultivars. Total isoflavone concentration was, on average, 40% greater in 2003 than 2002, which was characterized by above average temperatures and severe drought. Despite significant cultivar x year x site interactions, cultivars with consistently high and low isoflavone concentrations across environments were identified. Weak but significant positive correlations were observed between total isoflavone concentration and seed yield, 100-seed weight and crude fiber, indicating that isoflavone concentration is positively associated with other desirable seed characteristics.
