ABSTRACT

Phenolic compounds found in the black cherry, Prunus serotina Ehrh., seem to enrich this plant`s biochemical defense. The aim of the study was to analyze the tannin content in this invasive tree species. The condensed tannin content in the leaves of P. serotina was determined using vanillin method and it was demonstrated that it changed seasonally, reaching the highest values in July. The results of the histological study, performed in order to observe the tissue localization of the secondary metabolites, suggest that tannin compounds are accumulated mainly in the vacuoles of the upper epidermis and the palisade parenchyma. The observation of the main leaf veins also reveals frequent presence of tannin cells.

Key words: condensed tannins, black cherry, Prunus serotina, leaf anatomy.
