Turkish Journal of Agriculture and Forestry
Safflower (Carthamus tinctorius L.) callus cultures grown in the presence of different concentrations (0-100 µM) of cadmium were assayed for growth, Cd accumulations, and antioxidative responses. Cadmium inhibited the growth of calli by 25% and 46% at 75 and 100 µM Cd concentrations, respectively. Cadmium concentration in the calli increased with an increased Cd supply in the growth medium. Calli accumulated 334 mg Cd kg^{-1} of their dry weight at 100 µM Cd. Cadmium induced oxidative stress, which was indicated by modulating antioxidant (glutathione and \alpha-tocopherol) levels and antioxidative enzymes. The effect of Cd on glutathione (GSH) was dose-dependent. The …
