EVALUATION OF ARSENIC ACCUMULATION BY Colocasia esculenta (Kochu) FROM SOIL (Pages : 1 - 4)

An experiment was conducted for the evaluation of arsenic accumulation by kochu (Colocasia esculenta) from different concentration of arsenic contaminated soil during July 2012 to October 2012. Plants were grown on soil treated with different arsenic concentrations viz. A0; 0 mg/kg, A1; 500 mg/kg, A2; 1000 mg/kg and A3; 2000 mg/kg. From the experiment it was found that leaf number, plant height, leaf area, number of runner, number of sucker, plant leaf biomass and runner biomass were decreased significantly while the arsenic contamination level in soil increased. Kochu leaves accumulated 422.3, 751.7 and 973.5 mg/kg arsenic and kochu runner accumulated 178.8, 202.3 and 210.4 mg/kg arsenic when soil treated with 2000 mg/kg, 1000 mg/kg and 500 mg/kg arsenic respectively.Download
