Morphological Attributes of Glycine max (Soybean)

Heavy metal like lead and chromium present in environment in large quantities cause a severe environmental concern. Significant risks to the environment and agriculture are posed by heavy metal contamination of the air, water, and soil as a result of increased urbanisation and industrialization. Heavy metal pollution in soils can harm nearby ecosystems, groundwater, agricultural productivity, and human health because of its persistence and high toxicity. Heavy metals are accumulated in the tissues of plants growing in metal-contaminated soil, which can have a negative impact on the morphology of the plant. The present study was carried out to determine the effect of different concentrations (50ml, 100ml, 150ml and 200ml) of chromium and lead on morphological attributes of three varieties (JS:335, JS:80-21, JS:75-46) of soybean(Glycine max). The result of the present study showed that the exposure of Glycine max to Pb and Cr resulted in a decrease in total length, number of nodes and number of leaves of a plant. The shape of leaves in case of treated plants was also changed from ovoid to heart and oval shapes, at higher concentration of heavy metals. Among the three different varieties (JS:335, JS:80-21, JS:75-46) of Glycine. max(soybean) JS:335 showed maximum reduction and the JS:80-21 showed least reduction in the growth of a plant. Lead treatment proved more toxic than chromium treatment for all the three different varieties (JS:335, JS:80-21, JS:75-46) of Glycine max.
