Combined effect of Cr+6 and chelating agents on growth and Cr bioaccumulation in flood susceptible variety of rice Oryza sativa (L.) cv. Swarna

Purnaprava Mantry*, Hemanta Kumar Patra


Flood susceptible variety of Rice (Swarna) were grown in both water logged & water deficit condition. The experimental seedlings were treated with Cr+6 (10mg) and Cr+6 (50mg) both in the presence & in the absence of chelating agents (EDTA-Ethylene Diamine Tetra Acetic Acid, SA-Salicylic Acid, CA-Citric Acid). The results showed that the enhancement of Cr bioavailability in plants occurs by supplementing Cr+6 with chelating agents. This clearly depicts that the role of chelating agents increases the toxic effects of Cr+6 simultaneously increasing the rate of Cr accumulation in rice seedlings.
