ABSTRACT
This study investigates the impact of lead (Pb) contamination on the germination process of cowpea (Vigna unguiculata) seeds. Cowpea seeds were subjected to varying concentrations of lead in a controlled laboratory environment, and their germination rates and morphological parameters were observed and analyzed. The results demonstrate a dose-dependent inhibition of cowpea seed germination in the presence of lead, with higher concentrations leading to greater suppression of germination rates. Additionally, lead exposure was found to adversely affect root and shoot growth, resulting in stunted seedling development. These findings highlight the sensitivity of cowpea seeds to lead contamination and underscore the potential implications for agricultural productivity and environmental sustainability. Understanding the mechanisms underlying lead-induced inhibition of germination is crucial for devising effective strategies to mitigate heavy metal pollution in agricultural ecosystems and ensure food security.
