An electron probe X-ray microanalyser was used to study the occurrence of phosphorus, sulphur and calcium in the bud apices of dormant Scots pine (Pinus sylvestris L.). The material was collected during the winter months (November–February), fixed in Carnoy’s fluid, dehydrated, and mounted in paraffin wax. Of the 10 μm longitudinal section, the ones containing the middle portion of the apices were glued to the specimen supports and vacuum coated with aluminium. Three parallel line analysis were run over the corpus and the uppermost portion of the pith. Results obtained so far suggest that no marked changes occur in the position and level of the three elements during the study period.
