THE EFFECTS OF REACTIVE PHTHALOCYANINE BLUE TEXTILE DYE ON PEROXIDASE ACTIVITY, LIPID PEROXIDATION AND TOTAL CHLOROPHYLL CONTENT OF PHASEOLUS VULGARIS L. CV. GINA

In this study, the effects of Reactive Phthalocyanine Blue (RPB) changes on peroxidase, malondialdehyde (MDA) content and total chlorophyll content of Phaseolus vulgaris L. (bean) were examined. The beans were exposed to different concentrations of RPB between 200-1255 mg/L. In the analyzed plants, different effects were observed on peroxidase activity. When compared to the control group, a significant decrease was identified in the plants which were treated with RPB except for the 1255 mg/L application group. Besides the effects of RPB on MDA content were analyzed. MDA content was found to be lower in all application groups except for 439 mg/L. In addition, total chlorophyll content increased in all application groups except for 338 mg/L when compared to the control group. These findings indicated that RPB caused significant changes in peroxidase activity, MDA content and total chlorophyll. It was shown that the textile dye had a toxic effect on the plants.
