Abstract
THIS STUDY aimed to investigate the physiological and biochemical responses of common bean (Phaseolus vulgaris L. cv. Valentino) plants grown in virgin sandy soil incorporated with ceramic wastewater sludge (CWWS), at relatively low concentrations (0.5%, 1% and 2%), for 30 days. Within the different levels used of CWWS, especially at 1%, the enhancement of plants growth was generally proportional with the increase in leaf area and chlorophyll content, as well as it associated with higher uptake of P, N and K due to higher content of these metals in the CWWS- amended soil. Sucrose, proline and malondialdehyde (MDA) showed enhanced levels with the increase of CWWS application, while, glutathione (GSH) content of common bean plants showed attenuated levels. These results were in alliance with accumulation of higher levels of Fe and Cu metals inside the plant tissues. Antioxidant enzymes such as catalase (CAT), polyphenol oxidase (PPO), showed significantly enhanced activities with increasing the amended ratio of sludge. This increase was also accompanied with the increase in ascorbic acid (AsA) and total phenol contents and a decrease in the activities of ascorbate oxidase (ASO) and ascorbate peroxidase (APX).
