When considering the effect of heavy metals on trees generally and on forest ecosystems especially,
importance is given to their influence on seed germination in metal polluted soil. There is insufficient
data on this subject, especially when conifers are concerned. In this work, the influence of high
cadmium concentrations on percentage germination, specific activities and isoenzyme patterns of
catalase (CAT), superoxide dismutase (SOD), and peroxidase (POD) during the germination of Serbian
spruce [Picea omorika (Panč.) Purkynĕ] was studied. Cadmium chloride concentrations of up to 0.1 mM
did not cause an inhibition of germination, while 1 mM concentration inhibited germination and the
activities of catalase, superoxide dismutase and peroxidase. The isoenzyme profile of catalase and
superoxide dismutase did not change at high cadmium concentrations, while peroxidase expression of
basic peroxidase (B5) with pI value of 9.1 increased. This isoform of POD can play an important ...role in
the early development of Serbian spruce and its defense mechanism against heavy metals.
