Abstract

Morphological and biochemical changes in plant cells are known as important events for adaptation to stress. In this study, in Ctenanthe setosa leaves to which polyamines were applied during drought stress, changes in the activity of peroxidase, reducing sugar, proline and soluble protein levels were investigat- ed. The three common polyamines, putrescine, spermidine and spermine were exogenously treated through the leaves. The polyamines were sprayed onto the leaves at 5×10 –5 M. In the leaves to which polyamines were applied the peroxidase activity decreased, soluble protein increased. Also, it was deter- mined that putrescine and spermidine caused an increase in the amount of proline and in reducing sugar. However, increase was not observed in the leaves to which spermine was applied. In addition, we observed an increase in the activity of peroxidase, proline and reducing sugar levels, and a decrease in soluble protein level in the control ones and the leaves to which polyamines were applied during drought stress. As a result, the effect of polyamine on leaf rolling may be explained through the contribution to osmotic adjustment of the increase in proline, reducing sugar and soluble protein contents.
