Other claims from this paper (12)
- Mechanism The model attributed individual grain nitrogen accumulation rate to source nitrogen availability and sink accumulation capacity.
- Mechanism The modeled source availability was the sum of uptake and remobilization after anthesis.
- Mechanism The modeled sink rate depended on potential accumulation and temperature, water and nitrogen effects.
- Association Post-anthesis nitrogen uptake had a logarithmic relationship with increasing grain weight.
- Mechanism Nitrogen remobilization after anthesis drew on nitrogen in leaves and stems.
- Association Relative leaf and stem nitrogen content increased linearly with accumulated growing degree days before anthesis.
- Association Relative leaf and stem nitrogen content decreased linearly with growing degree days after anthesis.
- Method / resource The model fit pre-anthesis stem nitrogen uptake with R2 0.980 and RMSE 13.24%.
- Method / resource The model fit post-anthesis grain nitrogen uptake with R2 0.974 and RMSE 9.53%.
- Method / resource The model fit post-anthesis leaf nitrogen translocation with R2 0.970 and RMSE 10.93%.
- Method / resource The model fit post-anthesis stem nitrogen translocation with R2 0.976 and RMSE 9.29%.
- Method / resource The model fit grain protein content with R2 0.930 and RMSE 7.82%.
