Abstract
The toxic effect of lead on Pb accumulation from soil on tomato plant (Pusa ruby): growth parameters (shoot length, root length, fresh weight, and dry weight), chlorophyll content and lead content in plants with different concentration of lead: control, 0.05mg/L, 0.1mg/L, 0.15mg/L, 0.2mg/L). Elevated lead concentrations, particularly 0.2mg/L Pb, had a detrimental effect on the germination rate and the uptake of elements by roots, shoots, and leaves. Germination rate decreases as the lead concentration increases in the soil, at concentration of 0.2mg/L the germination ratio is about 1:10 which is around negligible. Plants exposed to increased Pb concentrations may display a diversity of detrimental symptoms, decrease in the germination rate, reduction in growth parameters (shoot length, root length, fresh weight and dry weight) blackening of the roots, dwarfism in plant height, growth retardation, and other symptoms. as well as the chlorophyll content (chlorophyll a, and a+b) and the tissue water content also decreases. Lead content on plant parts (root, shoot and leaf) increases as the lead concentration increases from control to very high concentration. We concluded that increased the lead concentration in the plants, the plants went through the various detrimental toxicity to avoid these toxicity and negative effect on plants we should use mitigation strategies on lead.
