Fig 3. Relation between N uptake from flowering to GS65+250 DD and grain N concentration at maturity for Récital (black circles) and Renan (white circles) exposed to two contrasting pre-flowering nitrate treatments N4 (italic labels) and N10 (regular labels) combined with two contrasting post-flowering nitrate treatments LN and HN.

Values are the means of five biological replicates ± 1 standard error.
