The Effect Of Cadmium On Growth And Antioxidant Responses In The Safflower (Carthamus Tinctorius L.) Callus, Shahram Namjooyan, Ramezanali Khavarinejad, Franceous Bernard, Shahrokh Namdjoyan, Hamed Piri
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 …

Seed Priming With Antioxidants Improves Sunflower Seed Germination And Seedling Growth Under Unfavorable Germination Conditions, Ivana Draganic, Slavoljub Lekic

The results of studying the effects of sunflower seed priming with an aqueous solution of ascorbic acid (A), tocopherol (T), and glutathione (G) performed prior to accelerated ageing and a cold test are presented in this paper. Germination, the percentage of abnormal seedlings, and the lengths of both roots and shoots were monitored. The results showed that the cold test caused a drastic drop in germination, an adverse effect on the shoot length, an increase in the percentage of abnormal seedlings, and no effect on the root length. Germination of seeds primed with the solution of A, T, and G …
