Summary:Lentil (Lens culinaris Medik.) is valued throughout the world for human and animal nutrition because of its high protein, vitamin, and mineral contents. Lentil production has decreased worldwide due to global warming. Although the physiological parameters of lentil plants have been examined under drought conditions, its tolerance mechanism has not been fully elucidated yet. In this study, lentil seedlings following germination were exposed to drought stress using 15% polyethylene glycol (PEG) application for 7 days. The untreated control plants were allowed to grow under conditions similar to that of germination. Oxidative stress responses (relative water content, chlorophyll content, [H.sub.2][O.sub.2] formation, lipid peroxidation, and proline accumulation) were compared in leaf samples of experimental and control group plants grown for 7 days under drought stress. Although the physiological and biochemical responses of the cultivars Firat 87 and Ciftci were close to each other, proline accumulation, malondialdehyde, and [H.sub.2][O.sub.2] levels were found to increase in the Sultan cultivar. Thus, it can be concluded that Firat 87 and Ciftci cultivars are more resistant to drought than the Sultan cultivar.
