Figure 3. Effect of 9 days preincubation of shoot cultures in the light with MS-medium containing 60 mM sucrose and 10 µM AIP. Endogenous levels of feruloylputrescine (FP) (upper panel) and caffeoyl­putrescine (CP) (lower panel) in µmol (g dry weight)-1 of the in vitrominituber cultures of S. tuberosum ssp. andigena 482W. Dark incubation with 240 mM sucrose, 22 µM BAP and 10 µM AIP applied to the MS-medium starting at day 0. Total levels ( FP,  CP) and levels in shoot ( FP,  CP), minitubers ( FP,  CP) and root ( FP,  CP) are shown. For arrow and mean values see Fig. 1.
