An experiment was carried out on effects of various factors on selenite uptake of excised rice roots. Results indicated that pH affected selenite uptake of excised rice roots significantly, which, however, was linked to forms of selenite. Low temperature inhibited uptake of selenite, but NaCl of a certain concentration promoted the uptake because temperature and NaCl might have an indirect effect on uptake of selenite by affecting metabolisms of the roots. The inhibition of selenite uptake by phosphate might relate to sharing of common absorption sites on root surface with selenite.
