| Abstract: | The effects of selenium compounds on growth of Catharanthus roseus (C. roseus) cell suspension culture and effects of pH on the selenium toxicity have been investigated. Cell growth and selenium uptake were monitored. Selenate (>0.5ppm Se) or selenite (> 0. 6ppm Se) inhibited C. roseus growth. Minimum lethal concentration (MLC) values were respectively 100 ppm Se(VI) and 2. 0 ppm Se (IV). Selenite was more toxic than selenate in the cell cultures. These compounds were enriched by C, roseus. In this plant-tissue culture, selenate and selenite had not antagonistic actions towards inorganic mercury. |
