The effects of Damavand volcanic ash on some morphological and physiological characteristics of Phaseolus vulgaris

Abstract

The purpose of this study was to investigate the effect of Damavand volcanic ash on the morphological and physiological characteristics of beans as a factorial experiment in a completely randomized design. The results showed that the highest dry leaf weight was observed in 100 mg/L treatment per liter of volcanic ash (0.0099 g). The results also showed that the optimal sugar content of the soluble sugar at 100 mg/L of volcanic ash was 0.650 (mg/g D.W.). The highest protein content and optimal peroxidase activity were observed with 0.68 (mg/g F.W.) and 0.082 (A470/mg/protein), respectively. Therefore, it can be argued that volcanic ash may increase plant growth and biosynthesis of organic compounds such as iron and aluminum.
