Simultaneousness of pollen shedding and stigma viability ratio was examined to clarify the phenology of reproductive organs of nine economically important sour cherry (Prunus cerasus) cultivars of ‘Erdi b?term?’, ‘Debreceni b?term?’, ‘Cseng?di’, ‘Kantorjanosi 3’, ‘Ujfehertoi furtos’, ‘Petri’, ‘Eva’, ‘Oblascinszka’, and ‘Pandy 279’. The main aim was investigating the possible influence of environmental cues in timing and development of phenophases and also response of different cultivars to seasonal cues. Likely effects of climatic changes on phenological development patterns were also considered. Results showed important aspects of the reproductive biology of sour cherry flowers. The amplitude of the phenophase ‘beginning of blossoming’ between cultivars did not exceed 6 days. There is a maximum of 3 days difference in the blooming length of different directions in each cultivar. ‘Pandy 279’ showed high variability when the position of flowers changed on the tree shoots. ‘Ujfehertoi furtos’ was stable in all four directions of the tree. The pollen shedding period and stigma viability ratio were synchronous. Pollen shedding phenomenon simultaneously occurred with the secretary activities of stigmas in all examined cultivars. Distribution of pollen shedding over the secretary activity of stigmas is almost good. In all five cultivars, maximum pollen shedding occurred when the temperature was high during the day. In general, the results of this experiment and our previous studies clearly demonstrate that the Pandy groups cannot be recommended for plantation in new orchards of Iran.
