Descripción
Context: Nitrogen and sulfur are critical yield-limiting factors that also impact the grain quality of bread wheat. The influence of the source/sink ratio on wheat grain weight has been widely studied, while its effect on quality parameters in genotypes with different baking aptitude has been addressed more recently, leaving processes to be unveiled. Objective: This study aimed to analyze the nitrogen and sulfur dynamics to changes in the source/sink ratio during grain filling in two Argentinean wheat genotypes, previously characterized by their contrasting sensitivity to assimilate availability. Methods: Field experiments were carried out during two growing seasons in Argentina under rainfed and nutrient sufficiency conditions. Three source/sink treatments were applied at seven days after anthesis: control, shading, and trimmed spikes. Determinations of nitrogen and sulfur were made on above-ground biomass, grain, and straw. Related variables were analyzed by linear regression. Results: The genotype of good baking quality showed a greater capacity to accumulate both N and S in the grain (y-intercept) than the one of poor quality, without differences in their stability (slope) against source/sink ratio variations. Grain N demand was more dependent on the remobilization of nutrient reserves stored in pre-flowering (59 % on average), while grain S demand was more dependent on nutrient absorption in post-anthesis (75 % on average). However, the S remobilized fraction increased as stress conditions during grain filling intensified. Conclusions: The carbon assimilate availability for grain growth during the filling period partially regulated the accumulation of N and S in the grain, although without genotypic differences in their stability against source-sink manipulation. Implications: These findings are relevant to optimize the nutritional management of bread wheat crops aimed at productivity with baking quality.
