Abstract

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.
