Mallow (Malva sylvestris L.) is a member of the Malvaceae family, a medicinal aromatic plant with pink flowers with purple stripes and is widely used in food and health fields. The aim of this study was to investigate the effects of drought stress on growth, water content and antioxidant defence system enzymes of mallow. Accordingly, relative Growth rate, osmotic potential, relative water content, lipid peroxidation, hydrogen peroxide content and antioxidant enzyme activities of superoxide dismutase (SOD), peroxidase (POX), catalase (CAT), ascorbate peroxidase (APX) and glutathione reductase (GR) were measured in the leaves of plants exposed to drought for 21 days. When plants under drought stress were compared with non-stressed plants, growth rate, relative water content and osmotic potential were significantly decreased. In addition, lipid peroxidation and hydrogen peroxide levels increased with drought stress. Plant defence system was stimulated under drought stress and SOD, POX, CAT, APX and GR activities were increased. In this study, the efficiency of antioxidant defence system in mallow exposed to drought stress was determined.
