Abstract
Agricultural sustainability and civilization of society enormously depend on land. However, contamination of soil due to heavy metals is a major threat to mankind. Cadmium is one of the most toxic metals in the environment and has noxious effects on vegetative growth. Lead is the second ranked of most widely distributed hazardous substances in the environment and can cause morphological, physiological, and biological dysfunctions in plants. This study investigates the effect of various concentrations of lead and cadmium, i.e. 400mg, 800mg, 1200mg, 1600mg Pb kg-1 and 5mg, 10mg, 15mg, 20mg Cd kg-1, on root length and shoot length of Cascabela thevetia (L.) Lippold. The results states lead treatments have decreased the length of shoot by 19 cm and 11.99 cm of root. Cadmium treatments to the plants have decreased by 20 cm and 11 cm of shoot and root respectively. Higher concentrations of heavy metals in the soil can significantly reduce root lengths and shoot lengths.
