"Pollutants containing heavy metals and toxic organic substances enter the ecosystem especially from applications of fertilizers, pesticides and other industrial products. Studies of plant responses to heavy metal stress are especially important for the understanding of a number of biological processes. On the other hand, study of influence of heavy metals on a tree is rather difficult, sometimes, almost impossible. Thus, possibilities how to simplify this kind of study is need. A using of cell cultures for the above mentioned purposes is one of these possibilities. Thus, we investigated influence of silver ions on early somatic embryos of Blue Spruce clone PE 14 by means of different electrochemical techniques. We were interested in the issue how much silver ions can embryos uptake during four days long treatment. For this purpose, we used optimized high performance liquid chromatography with electrochemical detection technique. The content increased with increasing treatment time and applied concentr" .
