以高油型东农47和高蛋白型东农48大豆品种为试验材料,采用沙培方法,研究高油型和高蛋白型大豆品种鼓粒期不同器官可溶性糖含量、蔗糖含量和果糖含量的积累规律。结果表明:东农47鼓粒期根系、叶片和荚皮的可溶性糖含量均呈上升趋势,茎秆的可溶性糖含量呈先升后降趋势,东农48叶片和荚皮的可溶性糖含量均呈双峰曲线变化规律,茎秆可溶性糖含量与东农47变化规律一致;东农47鼓粒期各器官和东农48鼓粒期叶片、茎秆和根系的蔗糖含量变化规律均呈先升后降趋势,且峰值都在鼓粒后第12天;东农47根系的果糖含量呈上升趋势,茎秆和叶片呈先下降再上升后下降趋势,荚皮呈先上升再下降后上升趋势,东农48除根系果糖含量呈上升趋势外,其它器官均呈先升后降趋势。高蛋白型东农48鼓粒期可溶性糖、果糖含量较高油型东农47高。高油型东农47鼓粒期蔗糖含量较高蛋白型东农48高。
Using high oil-type Dongnong 47 and high-protein Dongnong 48 soybean varieties as test materials, the sap culture method was used to study the soluble sugar content, sucrose content and fructose content in different organs of high oil and high protein soybeans Accumulate the law. The results showed that the soluble sugar contents of roots, leaves and pods of Dongnong 47 were all increased at the grain-filling stage of Dongnong 47, the content of soluble sugar increased first and then decreased, and the soluble sugar contents of Dongnong 48 were the same Bimodal curve and the content of soluble sugar in stem were the same as that of Dongnong 47.The sucrose content of leaves, stems and roots of Dongnong 47 in different organs of Dongnong 48 and Dongnong 48 were the highest The peak of fructose content in Dongnong 47 root system showed an upward trend. The stalk and leaf decreased first and then increased and then decreased, and the pod skin rose first and then decreased and then increased to the east. In addition to the root system fructose content of farmers 48 showed an upward trend, other organs showed the first and then decreased. High-protein type Dongnong 48 drum grain soluble sugar, fructose higher oil type Dongnong 47 high. High oil Dongnong 47 drum grain sugar content of high-protein type Dongnong 48 high.
