摘 要 ：本试验采用分部位去叶、遮光、环割果柄和测定茎枝的干物质积累等方法,研究了油菜的光合产物和贮藏物质对籽粒产量的影响,结果表明:(1)角果的光合产物是籽粒产量的主要来源,占2/3左右,其中果喙的光合产物约占籽粒产量的8％。(2)茎枝的光合产物对产量的贡献占13.5％,其中花序轴供给约5％。(3)茎枝中的贮藏物质对籽粒的灌浆结实

Abstract:Treatments of partial removal of leaves, shading and circumferential cutting ofpedicals were carried out and the accumulation of the dry matter in the stem andbranches of rapeseed plant was measured in order to study the influence of thephotosynthates and storage matter of different plant parts on t
