Ameliorative Effect of P and Ca, Mg, K Addition on Buckwheat in the Presence of Heavy Metal Stress

Öz

As an important agricultural plant, buckwheat (Fagopyrum esculentum) was used in this study. In order to examine the negative effect of heavy metal pollution, As, Cd and Pb were added to growth medium. On the other hand, for reducing the stress effect of metals P and Ca, Mg, K was also included. Obtained results showed that P was more effective than Ca, Mg and K addition for reducing the metal stress. It was observed that P addition aids to settle the decreased growth related parameters caused by heavy metal stress. Besides, P has balancing effect on the increased MDA and proline contents. It can be concluded that, although using Ca, Mg and K addition to fertilizers can reduce the damage caused by heavy metal pollution, P addition would be more effective and adequate to achieve efficient results.
