Abstract
Globally, urban areas are facing a rising issue of industrial pollution particularly due to heavy metals like Cadmium (Cd), which pose a threat to both plants and humans. However, plants response to Cd exposure varies based on factors like species, genetics, and growing conditions such as the type of soil and cultivation methods. This study focused on young tomato seedlings subjected to different Cd concentrations (0, 100, 200, and 300 ppm) through a pot experiment, aiming to understand the impact of Cd on various morpho-physiological traits of the "MAYAR F1" tomato cultivar. The results exhibited amazing findings that the chlorophyll contents (21.93 nmol/mg), relative water contents (0.84%), electrolyte leakage (135.5 uS/cm) and leaf area (6.37 cm2) were highest at 300 ppm followed by control. While the maximum number of leaves (11) were noticed in control. Consequently, the study suggests that cultivating tomatoes in urban agriculture soils contaminated with Cd could be a viable option. Nonetheless, it emphasizes the importance of exercising caution and conducting further research to fully comprehend the potential long-term implications and associated risks of Cd exposure in urban agriculture. Keywords: Heavy metal, cadmium; morphological traits, plant physiology, chlorophyll contents, electrolyte leakage.
