Abstract
Two experiments involving the growth of Lolium perenne seedlings were carried out by adding Se(VI) (as sodium selenate) or Te(VI) (as telluric acid) to the nutrient solutions and the plants allowed to grow for a further period of time. Se and Te concentrations in the shoots follow closely the level of Se or Te supplied in the nutrient solution. The uptake of Se and Te by shoots is higher thanin the corresponding root samples. Se and Te reduce the dry weight of both shoots and roots of this particular species. The significant effects of Se and Te which were observed on the uptake of some essential metals (Mn, Fe, Cu and Zn) into the roots did not extend to the shoots.
