A Comparative Analysis on Examining Heavy Metal Effects on Seedling Growth (Root and Shoot Length) in Raphanus Sativus Cultivar Pusa Rashmi Seedlings
Abstract: The study investigates the impact of copper, cadmium, lead, nickel, and zinc on the growth of Raphanus sativus cv Pusa rashmi, a prominent radish variety. Through controlled experiments with varying metal concentrations, this research observes their effects on seedling growth over ten days. Higher concentrations of these metals significantly reduce both shoot and root lengths in the radish seedlings. Cadmium and lead notably hinder shoot growth, while all metals inhibit root length, particularly at higher concentrations. Comparison with control groups highlights substantial growth reduction in metal - treated seedlings. Interestingly, Raphanus sativus cv Pusa rashmi shows relative resistance to heavy metal toxicity at lower concentrations of copper and nickel. These findings shed light on the nuanced impact of heavy metals on plant growth, suggesting a complex interplay involving enzyme function, hormonal regulation, and cellular alterations. Ultimately, this research enriches our understanding of how heavy metal pollution impedes radish plant growth, offering insights into the intricate mechanisms involved in these inhibitory effects.
