对１７ 个澳大利亚小麦品种的组织氮研究表明：品种间组织氮含量存在不同程度差异。叶片、茎秆和植株氮积累峰值分别出现在抽穗初期、灌浆初期和灌浆末期；花期前氮素主要积累在叶片中，花期后籽粒成为氮素最主要的贮藏器官。植株氮积累（ｇ／ｍ ２）与干物质积累呈极显著正相关，而与其果糖积累、籽粒产量、籽粒蛋白质产量及含量无显著相关关系；植株氮含量（ｇ·ｋｇ－ １）与其干物质积累、果糖含量和籽粒产量均呈显著负相关，与籽粒蛋白质含量显著正相关。
Tissue nitrogen of 17 Australian wheat cultivars showed that the nitrogen content of different tissues differed to some extent. The nitrogen accumulation peak of leaves, stems and plant appeared in the early heading stage, the early filling stage and the end of filling stage, respectively. Nitrogen mainly accumulated in the leaves before anthesis, and the grains became the main nitrogen storage organ after anthesis. Plant nitrogen accumulation (g / m 2) had a significant positive correlation with dry matter accumulation, but had no significant correlation with the accumulation of fructose, grain yield and grain protein yield and content. Nitrogen content (g · kg -1) and dry matter Accumulation, fructose content and grain yield were significantly negatively correlated with grain protein content was significantly positively correlated.
