Abstract

Soybean (Glycine max L.), belonging to Leguminosae, is an essential food in Asian countries. It has become a necessity to study the long-term effects of elevated concentrations of CO₂ on plant growth and development. Climate change may be affected by the increment of CO₂ and higher temperatures on crops. Elevated concentrations of atmospheric CO₂ can negatively affect the yield as well as the quality of the field crops. Alpha-tocopherol is the major vitamin E compound found in leaf chloroplasts. This antioxidant deactivates photosynthesis-derived reactive oxygen species and prevents the propagation of lipid peroxidation by scavenging lipid peroxyl radicals in thylakoid membranes. AL-Hunay is an electrical power plant main station located in the Al-Hofuf agricultural area in Saudi Arabia. The role of α-Tocopherol in mitigating the effect of CO₂ emitted from the AL-Hunay on the morphological and physiological traits of soybean has been investigated in this study by selecting a site of 100 meters apart from the station. The results revealed a negative effect of elevated concentrations of CO₂ on the morphological traits of soybean such as plant height, leaf area, and number of leaves. Furthermore, it also negatively affected the physiological traits such as the contents of P and K, mono- and disaccharides, chlorophyll a and b, and the activity of catalase, and superoxide dismutase. The results showed an obvious role of α-Tocopherol in mitigating the effect of elevated CO₂ on soybean plants through regulating the growth, stimulating photosynthesis, protecting the cell membrane and chloroplasts, and tolerating oxidative stress. The current study provides proof for the positive role of α-Tocopherol in mitigating the effect of elevated CO₂ emitted by the AL-Hunay power plant main station on the morphological and physiological traits of Glycine max L. plants.
