| 中文摘要: |
| 冬小麦节间形态结构模型是功能-结构小麦模型的重要研究内容。本研究以济麦22、泰农18和鲁原502为材料，于2013-2014和2014-2015年度开展了品种和施氮试验，并结合2013-2014年冬小麦节间主要形态参数和器官生物量等数据，通过分析不同节位节间同化物分配和节间主要形态参数与器官生物量的定量关系，构建了冬小麦节间主要形态结构模型。经2014-2015年小麦生长数据检验，除分蘖节间长模型模拟精度略低外，主茎节间长、主茎节间粗和分蘖节间粗模型精度均较高，所建模型可较好模拟不同品种与施氮水平下冬小麦节间主要形态结构。 |

| Internode morphological structure model is important basis for the function and structure model in winter wheat. We carried out field experiments in the growing seasons of 2013-2014 and 2014-2015 using winter wheat varieties Jimai 22,Tainong 18,and Luyuan 502 under different nitrogen application levels. On the basis of internode morphological-structure parameters and organ biomass data collected in the growing season of 2013-2014,the morphological-structure models of wheat internode were constructed with dissecting the photoassimilate distribution in the different internode,as well as the quantitative relationship between internode morphological-structure parameters and organ biomass. These models were then validated with an independent dataset collected in the growing season of 2014-2015. Except for internode length of tiller with lower precision,internode length of main stem,internode width of main stem,and internode width of tiller were all satisfactory to predict biomass of winter wheat. These models can be used to simulate internode structure in diverse varieties under different nitrogen application levels. |
