甘蓝型聚生角果油菜与甘蓝型单角果油菜的主要差异是花器官。聚生角果油菜的果皮面积比单角果增加５０％以上，聚生角果果皮光合速率高于单角果中油８２１、文油６号１７．４％～２０９％，光合产物转移到籽粒中的速度高于中油８２１、文油６号１３．４％～２３％，聚生角果２８６４、２９０４果皮光合作用对籽粒的贡献为６６％—７８．４％。每果柄粒重：叁角＞双果＞单角果。聚生角果吸收氮、磷的量和比例与蜀杂６号、中油８２１不同，蕾期吸收的磷在籽粒中的分配率与蜀杂６号差异较小而显著高于中油８２１；同位素示踪表明聚生角果油菜籽粒对１５Ｎ的利用率和分配率介于蜀杂６号和中油８２１之间。
The major difference between Brassica napus and Brassica napus is the floral organ. The pericarp area of polygamous rape increased more than 50% compared with that of monocotyledon, the photosynthetic rate of polygamous peel was higher than that of monocotyledonous oil, 821 and 17.4% -209% of that of monocotyledon, and the photosynthate was transferred to the grain Was higher than that of Peanut 821, Peanut 6, 13.4% -23%, and Peel 2864,2904 contributed 66% -78.4% of the photosynthesis to the grain. Weight per fruit: triangle> double fruit> single fruit. The amount and proportion of nitrogen and phosphorus absorbed by polygamous fruit were different from that of Shuza 6 and Zhongyou 821, and the distribution rate of phosphorus in buds at budding stage was less significant than that of Shuza 6 in the budding stage and significantly higher than that of Zhongyou 821. The results showed that the utilization rate and allocation rate of 15N for the polygamous rapeseed kernels ranged from Shuza 6 to PetroChina 821.
