摘要
以 2 0个大豆品种为材料 ,在鼓粒期至青荚期分期取样 ,对豆粒的蛋白质、游离氨基酸、脂肪、淀粉和可溶性糖及维生素C含量等生化物质进行测定。研究表明 ,随着豆粒的充实 ,各种生化物质不断增加 ,但达到最大峰值的时间不同。脂肪、蛋白质和氨基酸含量于鼓粒中后期达到峰值 ,淀粉和可溶性糖含量于鼓粒中前期达到峰值 ,维生素C积累主要集中在鼓粒前期。所以在菜用大豆鼓粒中期或后期即开花后 18～ 2 5d采收可保证较高水平的生化物质含量 ,最终保证菜用大豆的品质。经过综合评价 2 0个大豆品种的农艺性状、营养品质及外观品质 ,初步筛选出适合河北省种植的菜用大豆品种有绿 75、黑大粒、冀黄 10 4、日本A、D10 3、中黄 13。
In this experiment, the contents of protein, free amino acid, fat, starch, soluble sugar and vitamin C were determined from grain-filling time to green-pod period by use of twenty pre-selected vegetable soybeans. All the biochemical substances tested increased as the soybean grain filled, but reached their maximum at different time. The maximum of fat, protein and amino acid appeared at the mid-and late-time of grain filling, whereas that of starch and soluble sugar at early-and mid-time, and Vitamin C at early time. Higher level of biochemical substances could be gained, and so did the quality during the harvest time for vegetable soybean at mid to late grain filling period, or 18～25 days after flowering. The varieties, Lu75, Heidali, Jihuang104, RibenA, D103 and Zhonghuang13, were screen out as vegetable soybeans in Hebei province based on comprehensive evaluation of agronomic traits, nutrition quality and appearance.
