Effects of Chromium and Cadmium on Germination of Seed

Abstract

This study investigates the impact of heavy metals, specifically chromium (Cr) and cadmium (Cd), on the germination process of seeds. Heavy metal pollution is a growing environmental concern with detrimental effects on ecosystems, including soil and water contamination. In this experiment, seeds from a selected plant species were subjected to varying concentrations of chromium and cadmium in controlled laboratory conditions. The germination process was monitored, and key parameters such as germination percentage, germination rate, and seedling vigor were assessed. The results revealed a dose-dependent inhibition of seed germination in the presence of both chromium and cadmium. Higher concentrations of these heavy metals led to a significant reduction in germination percentage, delayed germination, and compromised seedling vigor. The adverse effects were attributed to the toxic nature of chromium and cadmium, which interfere with essential physiological processes in plant cells. Furthermore, the study explored potential mechanisms of heavy metal-induced stress on seeds, such as oxidative damage and disruption of cellular structures. Understanding the impact of chromium and cadmium on seed germination is crucial for predicting the long-term effects on plant populations and ecosystem health. The findings contribute valuable insights to the field of environmental science and could aid in the development of strategies for mitigating the negative effects of heavy metal pollution on plant life. This research underscores the importance of addressing heavy metal contamination to safeguard the sustainability of ecosystems and promote environmental conservation efforts.
