K. Shanker et al., EFFECT OF SELENITE AND SELENATE ON PLANT UPTAKE AND TRANSLOCATION OF MERCURY BY TOMATO (LYCOPERSICON-ESCULENTUM), Plant and soil, 183(2), 1996, pp. 233-238
Pot culture experiments containing sand and soil, at two levels of mer
cury (2 and 5 mu g mL(-1)) added through irrigation with increasing su
pplementation of selenium (selenite and selenate) led to a decrease in
the uptake of mercury by tomato (Lycopersicum esculentum) plant. Both
the forms of selenium (selenite and selenate) were found to be equall
y effective in reducing the mercury accumulation by plants. The observ
ed reduction pattern of mercury accumulation in plant tissues has been
discussed on the basis of the formation of insoluble HgSe complex in
soil-root environment.
