Résumé : | The nitrogen (N) utilization efficiency in hydroponically grown durum wheat was dissected during nitrate depletion at post-flowering stage. Feeding plants with low nitrate dose after anthesis lowered photosynthetic activity, triggered senescence, but induced N remobilization from vegetative parts. At harvest, tissue N concentration was 50% and 80% less important in leaves and culms, respectively, but similar in grains of N-deficient plants compared with control ones. |
