摘　　要：为了研究不同节位上大豆籽粒中5种脂肪酸与11S、7S球蛋白的含量变化规律,以吉林38和吉农19为试验材料测定不同节位籽粒中棕榈酸、硬脂酸、油酸、亚油酸和亚麻酸含量与11S、7S球蛋白含量。结果表明,吉林38和吉农19各节位籽粒中所含脂肪酸及11S、7S球蛋白含量不同。棕榈酸、亚油酸和亚麻酸含量表现为随节位的上升而逐渐下降,而硬脂酸和油酸含量则表现为随节位的上升而上升。11S球蛋白含量随节位上升呈现为先下降后上升的趋势,11S球蛋白含量在中下部（4~9节位）含量偏低,上部（13~17节位）含量达到最高;7S球蛋白与11S球蛋白含量在节位中的变化规律相反。相关分析表明,吉林38和吉农19的11S球蛋白与7S球蛋白呈负相关关系。11S/7S比值与棕榈酸、亚油酸和亚麻酸呈负相关关系,与硬脂酸和油酸呈正相关关系。To understand 5 fatty acids and 2 globulin（11S and 7S）contents in soybean from different nodes, cultivars Jilin 38 and Jinong 19 were used,and palmitic,stearic,oleic,linoleic,and linolenic acids were deter-mined. Results showed that 5 fatty acids and 2 globulin contents varied on different nodes of 2 cultivars. In higher nodes,palmitic,linoleic and linolenic acids increased,stearic and oleic acids decreased. 11S globulin on the mid-dle nodes（4 - 9）was lower than on other nodes,and were the highest on the upper nodes（13 - 17）. Correlation analysis showed that 11S and 7S globulin of 2 cultivars had negative correlation. The 11S / 7S ratio had negative cor-relation to palmitic,linoleic and linolenic acids,and had positive correlation to stearic and oleic acids.
