VN combinations correspond to the Variety and Nitrogen combinations. E, G, and P mean Exocet, Gamin and Pollen varieties, respectively. HN and LN correspond to high and low nitrogen fertilizations. EHN, Exocet High Nitrogen; ELN, Exocet Low Nitrogen; GHN, Gamin High Nitrogen; GLN, Gamin Low Nitrogen; PHN, Pollen High Nitrogen; PLN, Pollen Low Nitrogen. Inflorescence clipping experiment (ClipInflo) corresponds to the clipping of the apical inflorescence (ClipI0) and to the clippings of the apical and the four most apical inflorescences (ClipI4). Bud clipping inflorescences (ClipFB) corresponds to the clippings of buds on each of the four most apical inflorescences (ClipFB4) and on the seven most apical inflorescences (ClipBF7). Compartments are the roots, the main stem, the vegetative parts (stem and leaves) and the reproductive parts (pods) of primary and secondary axes.
