Table 2. Comparison of the endogenous levels of the hydroxycinnamoyl acid amides (HCA) caffeoylputrescine (CP) and feruloylputrescine (FP) and the free polyamines (PA) putrescine (Put) and spermidine (Spd) with the endogenous phytohormone activities in equivalents of GA3, zeatin, ABA und IAA as measured by Koda and Okazawa (14).

Developmental stage of tuber HCA and PA  (µmol / g dry weight) (this work) Phytohormone activity (µg / kg fresh weight) (ref. (14))
CP FP Put Spd GA3 ZEATIN ABA IAA
Stage A 0.007 0.001 2.6 3.4 2.2 0.2 0.7 5.9
Stage B 0.013 0.004 1.2 2.4 0.9 0.3 2.1 8.6
Stage C 0.017 0.007 0.8 1.5 0.4 1.1 10.9 6.5
Stage D 0.008 0.005 0.9 1.1 0.6 0.9 25.5 3.7



Stage A = unthickened stolon tips; Stage B = thickened stolon tips; Stage C = young tubers < 0.5 cm; Stage C = young tubers 0.5-2 cm.
