Interaction of auxins and cytokinins affects many aspects of plant development. In root and shoot apical meristems these hormones act antagonistically in order to maintain the balance between the formation of new cells and their differentiation. The aim of the experiment was to determine the effect of benzyladenine and its cooperation with 1-naphthaleneacetic acid on rooting and development of aerial parts of Fuchsia hybrida cuttings and their subsequent growth. Anatomical analysis of rooting process was also undertaken. Cuttings were treated with BA, NAA or BA and NAA together. BA applied by quick-dip method, delayed root initiation and development and negatively affected the number of primordia. Under the influence of BA cell organization took place in meristem of smaller size. Independently on the year of research and way of treatment BA inhibited adventitious root development, even with the use of NAA. BA, regardless of the presence of NAA, stimulated lateral shoot formation on Fuchsia cuttings, applied by spraying, stimulated also shoot elongation. This effect diminished during subsequent development of plants.
