EFFECTS OF ARSENIC CONCENTRATIONS AND FORMS ON GROWTH AND ARSENIC UPTAKE AND ACCUMULATION BY INDIAN MUSTARD (BRASSICA JUNCEA L.) GENOTYPES

Sa？etak By using two Brassica juncea genotypes (Varuna and DHR-9504) a green house experiment was carried out during crop cycle (2003-2004), at Agricultural Farm, Bilaspur, Chhattisgarh, India. In Indian mustard, arsenic extraction by plants increased signifi cantly with increasing arsenic concentrations in soils. Uptake of arsenite by Indian mustard genotypes was higher than that of arsenate. Stunted growth of the plants was also observed in this study. This experiment clearly demonstrated the existence of genotypical variations in tolerance to As toxicity among Brassica juncea genotypes
