摘要: 【目的】 研究粒重不同大豆籽粒蛋白质、脂肪和可溶性糖在籽粒灌浆过程中积累动态差异及生理机制,为不同用途大豆的栽培和选育提供理论依据。【方法】 选取百粒重分别为7.13、20.21和30.54 g左右的小粒大豆、普通大豆和大粒大豆为材料,测定关键生育期叶片光合速率,分析3种大豆籽粒形成过程中干物质重、蛋白质、脂肪和可溶性糖浓度变化以及相互关系。【结果】 小粒大豆叶片光合高峰持续期短,且高峰期比普通大豆和大粒大豆提前10 d。鼓粒前期(0~20 d)小粒大豆籽粒所积累干物质达到最终干物质重的82%,而普通大豆和大粒大豆分别为49%和66%;整个鼓粒期,大粒大豆籽粒中可溶性糖含量显著高于普通大豆和小粒大豆,普通大豆籽粒中蛋白质浓度显著低于小粒大豆和大粒大豆;籽粒发育前期,小粒大豆和大粒大豆的脂肪积累速率明显高于普通大豆。鼓粒前期,3种大豆籽粒干物质重与可溶性糖呈正相关,后期呈显著负相关;普通大豆和大粒大豆脂肪浓度与干物质重呈显著正相关,大粒大豆脂肪浓度与可溶性糖和蛋白质浓度均呈显著负相关,小粒大豆的蛋白质、脂肪和可溶性糖浓度相关性不显著。【结论】 粒重不同大豆籽粒蛋白质、脂肪和可溶性糖含量差异明显;鼓粒前期是小粒大豆籽粒干物质积累的快速期和关键期,对籽粒的物质积累至关重要,而鼓粒后期对普通大豆和大粒大豆的物质积累同样重要。

Abstract: 【Objective】 This study aimed to (1) examine the differences in the accumulation of protein, oil and free soluble sugar in different seed size soybean cultivars during seed filling stage and (2) evaluate relevant physiological mechanism. The outcomes of this study will provide a scientific basis for better cultivation and cultivar breeding for soybean withdifferent commercial purposes.【Methods】 Three soybean cultivars, small-seedsoybean (7.13 g/100-seed), normal-seed soybean (20.21 g/100-seed) and big-seed soybean (30.54 g/100-seed), were planted in field condition. We examined leaf photosynthetic ratesduring thekey growth stage, quantified seed protein, oil, free soluble sugar concentration and dry matter weight during seed filling and evaluated their relationships.【Results】 Relatively shorter peak period of photosynthetic rate was found in small-seed soybean and its maximum photosynthetic rate was 10 d earlier than that of normal-seed and big-seed soybean. The accumulated ratio of dry matterwas significantly different among soybean cultivars during the initial 0-20 d seed filling period. The accumulated dry matterin this stage accounted for 82% of final seed weight in small-seed soybean, whereas it was 49% and 66%, respectively, in normal-seed soybean and big-seed soybean. The seed free soluble sugar concentration in big-seed soybean was significantly higher than that of small-seed soybean and normal-seed soybean, whereas the seed protein concentration in normal-seed soybean was significantly higher than that of small-seed soybean and big-seed soybean during the whole seed filling stage. The accumulation ratios of oil in small-seed and big-seed soybean were higher than that of normal seed soybean in the early seed filling stage (0-20 d). The correlation between seed dry matter and seed free soluble sugar concentration was significantly positive during the early seed filling stage, but significantly negative during the late seed filling stage in soybeans. The seed oil concentration was positively correlated with seed dry matter mass in normal-seed and big-seed soybean, but negatively correlated with seed protein concentration and free soluble sugar concentration in big-seed soybean during the late seed filling stage. No significant relationships were found among seed protein, oil and free soluble sugar concentration in small-seed soybean at the same stage.【Conclusion】 Significant differences existed for seed protein, oil and free soluble sugar concentrations in soybeans with different seed size. The early seed filling stage (0-20 d) is the key and fast period for dry matter accumulation, which is more critical for the total matter accumulation in small-seed soybean. Whereas the late seed filling stage (30-50 d) is as important as early-seed filling stage in normal-seed and big-seed soybean for total matter accumulation.
