The process of phloem formation in Norway spruce (Picea abies [L.] Karst.) was analysed during the growing season 2009 in Rájec-Němčice locality (Czech Republic). The research series consisted of research plots with 34 and 105 years old spruce monocultures. The formation of phloem cells was determined by the examination of small increment cores taken once a week. Cross-sections of tissues were studied under a light microscope. Cambium activation was observed on 9 April both in young and old trees. On the same date the first newly formed cells of early phloem were observed in old trees but in young trees one week later. Although the time of early phloem formation was 14 days longer in old trees, there were no large differences in the numbers of formed cells. The beginning of the longitudinal axial parenchyma formation was determined in young trees on May 14. In old trees this activity was seen a week later. The influence of air temperature and soil moisture was also analysed in relation to phloemogenesis.
