We studied temperature dependence of POD activity in the extract from omorika needles (Picea omorika (Panc.) Purkinye). Chosen temperatures were in physiological range. We used two substrates - guaiacol and coniferyl alcohol, and measured POD activity using UV - VIS spectrophotometry. In case of both substrates there was an increase in maximal velocity of the enzyme reaction with temperature at lower temperature range. At the temperature 30 deg C POD maximal velocity in reaction with guaiacol attained a maximum, while activity with coniferyl alcohol showed a permanent increase.
