Abstract

By using two Oryza sativa genotypes (Mahsuri and CN1035-60) a green house experiment was carried out to study i) genotypic variation in Arsenic (As) tolerance, and ii) As concentrations in different plant- parts at Agricultural Research Station, Bilaspur Chhattisgarh, India during 2010-2011. Plants were grown under controlled climatic conditions and subjected to increasing As supply in the form of Na2HAsO4 @ 0, 10, 20,30,40,50 mg As/kg soil. Mahsuri showed greater sensitivity to As toxicity than CN1035-60. Increasing As supply markedly reduced the stem and root dry weight of both genotypes (Mahsuri and CN1035-60) and these decreases were more marked in Mahsuri. Increase in As concentration of about 5 times in stem and 9 times in root was noted with an application of 20 mg As/ kg soil than the control. As was accumulated in the roots in much higher amounts than in the stem, especially in the case of CN1035-60 indicating that there is limited transport of As from the root system to the above ground plant parts in CN1035-60. Genotype CN1035-60 had significantly less uptake of As than genotype Mahsuri.
