- ... Genotypic variation in nitrogen efficiency of winter oilseed rape is closely related to variation in post-flowering N uptake. In this study the hypothesis was tested that assimilate supply from the leaves is decisive for a high N uptake during reproductive growth.Two winter oilseed rape cultivars differing in N efficiency were cultivated in a three-year field experiment at three N rates, ranging f ...
