Partitioning of excitation energy in two wheat cultivars with different grain protein contents grown under three nitrogen applications in the field

Influences of different nitrogen applications on photosynthesis and utilization of excitation energy were explored by comparing two field‐grown wheat ( Triticum aestivum L.) cultivars with high or low grain protein content [High protein cultivar ‘8901’ (HC) and low protein cultivar ‘1391’ (LC)]. High nitrogen application significantly decreased both CO 2 assimilation and photorespiration in both cultivars during the early stages after anthesis....
