摘　　要：大豆籽粒干物质积累是产量构成因子之一,脂肪和蛋白质的含量是大豆的品质指标,因此对大豆籽粒干物质及品质性状积累规律进行研究是必要的。本研究利用不同基因型大豆品种从物质运输和物质转化角度对不同节位籽粒干物质、脂肪、蛋白质的动态积累进行分析。结果表明:(1)籽粒干物质动态积累呈"S"型曲线变化,无基因型差异;籽粒干物质的积累是源库流互作的过程,由于库竞争的存在,致使干物质积累量存在节位差异;(2)脂肪含量的增加呈先快后慢、最后趋于缓慢的S型曲线,蛋白质的积累大致呈W型曲线变化,二者积累关键期在生殖后期;(3)脂肪和蛋白质积累在生殖后期呈显著负相关,从能量角度分析二者存在相互转化。The ability of soybean seeds to accumulate dry matter is a fundamental component of the yield, quality index of soybean is oil and protein content. Research on dynamic accumulation of dry matter and quality is necessary. Dynamic accumulation of dry matter, protein and oil were analyzed in different node location by matter transport and matter transform using different genotype soybean variety. The results showed that： （1）： dry matter accumulation showed typical ＂S＂ curve and there were not difference of genotype; accumulation of dry matter of seed is the process of interactions between source, sink and flux and there was difference of genotype; there was node location difference in dry matter weight because of sink competition; （2） oil accumulation was fast on ealy maturation but became slow later and showed typical ＂S＂ curve, protein accumulation was a ＂W＂ curve, moreover late maturation were their key period of accumulation; （3） oil and protein content were significant negatively correlated for late maturation, they maybe transform one another in energy.
