| 摘 要： | 通过田间试验，分析不同种植密度条件下油菜后期的源库大小，结果表明：（1）群体中角果皮面积占总光合面积的比例随密度的增加而逐渐下降，茎杆和分枝的面积比例逐渐增加，但其变化幅度较小；（2）每角粒数随密度的增加呈下降的趋势，密度较小时下降的幅度小，密度较高时下降的幅度大；（3）单个籽粒体积、每角籽粒总体积、单位角果皮面积承担的籽粒数（SNPA）和单位角果皮面积承担的籽粒体积（SVPA）随密度的增加呈先增后减的趋势。

| Abstract: | The experiments were focused on investigation the effects of plant density on source and sink for winter rapeseed during seed filling stage.The main results were as follows.(1) The percentage of pod area in total photosynthetic area decreased and the percentage of stem and branches area increased as the density increased.But the changes were little.(2)Seed number per pod decreased as the density increased.It decreased less in lower density than that in higher density.(3)The seed volume per seed,total seed volume per pod,seed number per pod area(SNPA) and seed volume per pod area(SVPA) increased firstly and then decreased as the density increased. |
