Thirteen low-tannin faba bean genotypes grown at two locations in north central Alberta in 2009 were evaluated to investigate the variation in seed characteristics, phenolic and phytate contents, and phytase and antioxidant activities and to elucidate the relationship of these components as a breeding strategy. Seed characteristics including color were predominantly genotype dependent. The faba bean genotypes with total phenolic content ranging from 5.5 to 41.8 mg of catechin equiv/g of sample was linearly related to tannin content and the best predictor of antioxidant activity. Phytic acid content and phytase activity varied significantly among genotypes and between locations, ranging from 5.9 to 15.1 g/kg and from 1606 to 2154 FTU/kg sample, respectively. Multivariate data analysis performed on 19 components analyzed in this study using principal component analysis (PCA) and cluster analysis demonstrate that differences in seed characteristics, phenolic components, phytic acid, and phytase are major factors in segregating faba bean genotypes. The relatively low phytic acid content and high phytase activity of these low-tannin faba bean genotypes are beneficial/essential traits for their use in human and animal nutrition.
2009 年，在艾伯塔省中北部的两个地点种植了 13 个低单宁型蚕豆品种，对其进行了评价，以研究种子特性、酚类和植酸含量、植酸酶和抗氧化活性的变化，并阐明这些成分之间的关系，作为一种育种策略。种子特性，包括颜色，主要取决于基因型。总酚含量在 5.5 至 41.8mg 儿茶素当量/g 样品之间的蚕豆基因型与单宁含量呈线性相关，是抗氧化活性的最佳预测因子。植酸含量和植酸酶活性在基因型和地点之间差异显著，范围分别为 5.9 至 15.1g/kg 和 1606 至 2154FTU/kg 样品。使用主成分分析（PCA）和聚类分析对本研究分析的 19 个成分进行的多元数据分析表明，种子特性、酚类成分、植酸和植酸酶的差异是分离蚕豆基因型的主要因素。这些低单宁型蚕豆品种相对较低的植酸含量和较高的植酸酶活性是其在人类和动物营养中应用的有益/必需特性。
