| Abstract: | Garden rocket (Eruca sativa L.) plants grown in sand culture were irrigated with normal 1/10 Hoagland's medium low sulfate (SO42?)] or with double SO42? concentration (high SO42?), each supplemented with 0, 2, 10 ppm SeO42? as sodium selenate for 30 days. Increasing SO42? concentration in the nutrient medium diminished SeO42? uptake, foliar hydrogen peroxide (H2O2), and MDA via enhancing the glutathione pool and their enzyme activities. These results showed that increasing SO42?/SeO42? ratio in nutrient medium of rocket plants played an important role in selenate detoxification. |
