Wheat (Triticum aestivum L.) seeds were used to study a possible relationship between strontium and polyamines (PAs) in the coleoptile, root, and endosperm during germination. When $Sr^{2+}$ (0.001 mM + 10 mM) was applied to the incubation medium with $10;{mu}M$ $GA_3$, great increases in putrescine (Put) were observed in root and spermidine (Spd) in the coleoptile, depending on the concentration. In germinating seeds, putrescine accumulation was induced even at a low concentration (0.01 mM Sr), whereas spermidine accumulation was stimulated considerably at a high concentration (10 mM Sr). The putrescine levels, on a gram fresh weight (g-fr-wt) basis, in the roots which were growth-inhibited by 1 and 10 mM $Sr^{2+}$ were 22.4 and 15.3 fold higher respectively than at the same concentrations of $Ca^{2+}$. The accumulation of total polyamine (TA), in particular Put and Spd, induced by Sr seemed to be an important physiological response not only on a g fr wt basis but also on an RNA basis. In contrast, the levels of agmatine (Agm) and cadaverine (Cad) were notably enhanced by 10 mM $Ca^{2+}$ in the coleoptile and root. Cadaverine was detected only in $Ca^{2+}-treated$ seedlings. However, $Ca^{2+}-treatment$ in the range of 0.001 mM to 1.0 mM resulted in reduction of TA content. The distinction of accumulated polyamines and the change in diamine (DA) / TA and tri- and tertiary (tPA) / TA ratios were likely to be a physiological difference between $Sr^{2+}$ and $Ca^{2+}$ during germination in wheat.
