Abstract

Due to its wide industrial use, Cr is considered a serious environmental pollutant. Toxicity of Cr varies with its valence state (Cr+3 and Cr +6). In the present study, the uptake of Cr+6 were studied in drought resistant and drought susceptible variety of rice by applying two concentrations of Cr 10mg and 50mg/Kg of soil supplementing with various chelators such as Ethylene Diamine Tetracetic Acid (EDTA), Salicylic Acid(SA) and Citric Acid(CA). Accumulation of chromium showed an increasing trend with gradual increase in chromium concentration from 10mg to 50mg/kg of soil. Both the varieties of plants were grown under water logged and drought condition. Supplementation with chelating agents also showed an increase trend of chromium accumulation in presence of EDTA than SA and CA. The drought resistant variety showed more Cr-uptake than the drought susceptible variety when grown under both drought condition and water logged condition. The treatment of Cr 50mg with EDTA depicts more uptake or Cr than all the treatments. The result of the present study may help in phytoremediating heavy metal pollutants from the environment.
