The biological material used to determine the enzyme activity was represented by: plants harvested from the ex vitro environment (from Ceahlău Mountain) and plants grown in vitro (plantlets provided in the Laboratory of Genetics and Plant Biotechnology of the University „Vasile Alecsandri” from Bacău). This current study presents the results concerning the enzyme activity in Rhodiola rosea L. The biochemical analyses on the individuals of Rhodiola rosea L. aimed to depict the fluctuations in the activity of peroxidase, catalase and superoxyd dismutase depending on the growth medium that provided these plants/plantlets. The data of our tests on the activity of some enzymatic systems in the plants of Rhodiola rosea L. do not imply a significant influence of the environment on the metabolic processes that take place in the analyzed individuals (obtained either ex vitro or in vitro).
