Kinetics of dry matter (DM) of Aviso and Oase under ample or low N supply. The plants were supplied with ample (HN, 3.75 mM) or low (LN, 0.375 mM) concentrations of nitrate. Dry matter is expressed in g per plant for Aviso (A,
C) and Oase (B,
D) at 0 (early bolting), 42 (pod formation), 70 (start of seed filling) and 99 (mature seeds) days after the beginning of bolting (D0). Seeds and pod walls were grouped and called siliques at D42 and they were separated from D70 onwards. Data are indicated as the mean value ± standard error (vertical bars). Different letters (a, b, c) indicate that the total dry matter is significantly different between two dates. Hashes represent significant differences between genotypes in HN or LN conditions and the asterisks represent significant differences between N treatments (n = 4 plants; p < 0.05).
