摘要：

<正> Translocation of previously accumulated nitrogen and carbohydrates from vegetative tissue of the wheat plant is a major assimilate source for grain filling. This study was conducted to examine genotype differences in nitrogen and fructan translocation and their relationships to grain yield and protein content. Effects indicated that significant genotype differences existed for nitrogen accumulation at anthesis and fructan at milk stage and their translocation. Two high protein genotypes, Cunningham and PST90-19, accumulated more nitrogen before anthesis and had greater nitrogen translocation, but lower post-anthesis nitrogen uptake,
