N fluxes in Aviso (A) and Oase (B) in HN conditions between D70 and D99. The plants were supplied with an ample concentration of nitrate (HN, 3.75 mM of nitrate). D70 corresponds to the start of seed filling and D99 to the mature seed stage. Fluxes of N from remobilization or uptake in the different organs are expressed as mg of N remobilized or taken up, respectively. A shaded box means that the organ was not present during these growing stages. For fluxes of N remobilization, the N amount is indicated with a minus sign (−) when N is remobilized from a source organ, or it is indicated with a plus sign (+) when remobilized N is redistributed towards a sink organ. Data are indicated as the mean value ± standard error. Hashes represent significant differences between genotypes (n = 4 plants; p < 0.05).
