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. M3 10.52547/nbr.7.3.346 ER -
