Investigation physialogical Characteristics of Ricinus Communis (L.) and Brassica juncea (L.) in cadmium contaminated soil

Nesa Gharebaghli

Abstract


We have previously reported that Ricinus  communis (castor) is more tolerant to soil cadmium (Cd) and more efficient for Cd phytoremediation than Brassica juncea (Indian mustard). This expriment was performed to Investigation physialogical and biochemical characteristics of Ricinus Communis (L.) and Brassica juncea (L.) in cadmium contaminated soil. Castor plants showed stronger self- protection ability in form of proline bioaccumulation (r2= 0.949) than Indian mustard (r2= 0.932), Proline accumulation increased by 2.6 fold in B. juncea and 17.7 fold in R. communis on 90 DAS applied in cadmium contaminated soil. whereas a lower r2 for malondialdehyde (MDA) and total soluble protein in R. communis (r2= 0.914 and r2 = 0.915, respectively) than that of B. juncea (r2 = 0.947 and r2= 0.927, respectively) and there was increase of MDA by three fold in   B. juncea and 3.36 fold in R. communis over the control that indicated a greater damage to cell membrane in Indian mustard during the stress conditions.
