dc.description.abstractDIFFERENTIAL RESPONSES OF ANTIOXIDATIVE SYSTEMS AND PHOTOSYNTHETIC PIGMENTS IN THE LEAVES OF QUERCUS AUCHERI (BOZ PIRNAL OAK) UNDER DROUGHT STRESS CONDITION Hakan, Ö. - Gulriz, B. Istanbul University Drought is the most important stress factor determining plant growth and productivity world-wide. The aim of the present study was to investigate disturbances of antioxidative systems and photosynthetic pigments in the leaves of Quercus aucheri which are endemic for Turkey under drought stress condition. 6 months old plants were treated with drought stress for 4 weeks. At the end of the treatment period, contents of photosynthetic pigments, levels of lipid peroxidation, levels of reduced glutathione (GSH) and oxidized glutathione (GSSG) and activities of antioxidant enzymes such as superoxide dismutase (SOD), glutathione reductase (GR), ascorbate peroxidase (APX), guaicol peroxidase (GPX) and catalase (CAT) were determined in the leaves of Quercus aucheri. 4 weeks drought stress significantly decreased contents of photosynthetic pigments while increased the levels of lipid peroxidation in the leaves of Quercus aucheri. Levels of GSH were significantly decreased while levels of GSSG were significantly increased in the leaves of Quercus aucheri at the 4 weeks drought stress treatment. The activities of CAT, AP and GR were significantly decreased while activities of SOD and GPX were significantly increased in the leaves of Quercus aucheri at the 4 weeks drought stress treatment. The results indicated that 4 weeks drought stress may induce oxidative stress and cause differential responses on the antioxidant enzymes in the leaves of Quercus aucheri. The present study would contribute to future studies on Quercus species which are endemic for Turkey under drought stress conditions.
