The goal of the study was to determine the phyllochron and leaf senescence on the main stem. Plant samples for analyses were taken every 7-10 days from the beginning to the end of vegetation. There were 5 plants analysed towards development stage, total number of leaves on main stem and a number of leaves photosynthetic actives. For all years, number of leaves on the main stem increased linearly with cumulative degree-days. The phyllochrons for all years under study reached were averaged 105.3 deg C
