ACCUMULATION OF ARSENIC IN RADISH (RAPHANUS SATIVUS L.), AND THEIR EFFECTS ON GROWTH AND ANTIOXIDANT ACTIVITIESAbstract
This study investigated the effects of arsenic on radish in the pot (green house experiment), result revealed that length, FW and DW of plant (EDP and leaf) was significantly (P < 0.05) affected at higher concentration of As (≥40ppm) treatment. Chl-a and Chl-b was significantly affected at >40ppm As treated plant compared with C*. TSS and Proline content in plant showed, increasing trend at increasing concentration of As treated plant. Ca, P and K content in plant was more after 30 DAS followed by 60DAS, P was significantly (P<0.05) more affected from 10 to 80ppm of As treated plant as compared to Ca and K. APX and CAT activities of As treated plant leaf showed increasing trends from C* and DAS. About 70 µg of As /g of DW of EDP accumulate after 60DAS at ≥ 40 to 80ppm, it was more than leaf. As uptake by the EDP was significantly more in 60DAS (R² = 0.810) than 30DAS (R² = 0.753) as compared with C*. BCFs was >1 for the As treated plant at >40 and 50ppm after 60DAS.
