Fig. 3. Accumulation of anthocyanins in seedling hypocotyls (a) and roots (b) in the WT, atv, Aft and SB genotypes, after 12 d of growth in dark (black bars), continuous light (white bars) or 16/8 h day/night photoperiod (gray bars). Accumulation of anthocyanins in roots (c) in the same genotypes, in control conditions or with the germination solution supplemented with 100 mM sucrose (S100), 50 mM gibberellic acid (GA50) or the two components together (S100 þ GA50). Treatments and light
inductive conditions were given 4 d after the first imbibition of the seed. Bars represent mean values SEM; means indicated by the same lowercase letter within growth treatment are not significantly different for P 0.05.
