A greenhouse experiment was carried out with the aim of evaluating the effect of sulphur sources, in the presence or absence of additives (urea and glucose), on the sulphur uptake by bean leaves. The treatments: solutions of sulphuric acid, ammonium, potassium, magnesium, manganese and zinc sulphates labelled with 35S, containing or not the additives, were applied to the first trifoliate of the plants to assess the sulphur uptake and translocation. The results enable to conclude that 33% of the added sulphur was absorved, and 27% out of this total was translocated. The additives did not have any influence on uptake and translocation. The sulphuric acid and ammonium sulphate solutions were the best sulphur suppliers for the bean plant.Downloads
