Endogenous levels of feruloylputrescine (FP) (upper panel) and caffeoylputrescine (CP) (lower panel) in µmol (g dry weight)­1 during the dark incubation period of the in vitrominituber cultures of S. tuberosum ssp. andigena 482W. Series with 240 mM sucrose and 22 µM BAP added to the MS-medium (+BAP).

Levels in shoot ( FP,  CP), minitubers ( FP,  CP) and root ( FP,  CP) are shown. For total levels, arrow and mean values see Fig. 1.
