Effects of cadmium (Cd) on in vitro cultures of Cryptocoryne elliptica

Abstract

The use of plants to clean and minimized the accumulation of heavy metals in contaminated site has generated much interest of researchers. In this study, the ability of Cadmium (Cd) in Cryptocoryne elliptica was investigated and also the soluble protein content. In vitro plantlets of Cryptocoryne elliptica were exposure with 200µM cadmium for 30 days. The cadmium uptake was measured by using Inductively Coupled Plasma Mass Spectrometer (ICPMS) in every 5 days. Cadmium accumulation generally increases with increasing of exposure periods. Roots content the highest amount of cadmium compared to leaves and petioles which was 1.24-folds and 1.73- folds respectively. Roots was the highest part in soluble protein content which was 1.07-folds and 1.10-folds compared to leaves and petioles. Cadmium found to increase the soluble protein content in plantlets especially in roots.
