Abstract:
Chromium (Cr) is a non-essential element that is found in the environment as one of the dangerous heavy metals. Maize is a cereal that is utilized as a source of food for both plants and humans, and it is also grown on metal-contaminated soils, mostly to feed the world's growing population. As a result, screening low Cr-accumulating maize varieties could be an environmentally friendly option, particularly in Cr-contaminated soils. For this purpose, a pot experiment was carried out at Botany Department, University of Sargodha, Sargodha, Punjab, Pakistan. Seeds of two maize cultivars (Malka-16 and FH-1046) were grown in pots containing soil. The plants were irrigated with different chromium concentrations (0, 10, 20, 30, 40 ppm) after two weeks of germination. The plants were harvested after 45 days of germination. Different physiological and morphological characters were measured. Results showed that reduction in all parameters by increasing chromium concentration. Chromium addition increased the concentration of chromium in roots and stem. Leaves accumulated lowest chromium. Results also showed that cultivar FH-1046 accumulated lowest chromium concentration and performed in a sustainable way while Malka-16 accumulated highest chromium concentration. So, FH-1046 might be used to grow at chromium contaminated soils to avoid any loss in nutritional value and its entry to food chain. But field studies are necessary before practical application.
