The Effect Of Salt Stress On Antioxidative Enzymes And Proline Content Of Two Turkish Tobacco Varieties, Özge Çeli̇k, Çi̇men Atak
Turkish Journal of Biology
The aim of this study was to compare the salinity tolerances of 2 oriental tobacco varieties (İzmir Özbaş and Akhisar 97). Salinity stress experiments were performed under both in vitro and in vivo conditions. Seedlings of each variety were subjected to 0, 50, 100, 150, 200, 250, 300, and 350 mM NaCl. Photosynthetic pigment levels, lipid peroxidation rate, total protein content, antioxidant enzyme activities, and proline concentrations were determined for seedlings treated with salt for 14 days. The Akhisar 97 variety was found to be more sensitive to salinity stress than the İzmir Özbaş variety. Although proline is thought to …
