Treść
This paper presents the results of 3-year phenological observations of Callery pear (Pyrus calleryana) trees growing in green areas in the city of Poznań. The study was carried out in the years 2010, 2012 and 2013 at four localities of the species representing two cultivars of Callery pear: ‘Chanticleer’ and ‘Capital’. The observations included the course of leaf development, leaf colouration and leaf fall, as well as fruit ripening and fall. Sixteen phenophases were taken into account. The observed trees were characterised by a long vegetation season lasting for approx. seven months, plentiful flowering lasting on average 15–19 days, attractive autumn leaf colouration and an exceptionally long period of leaf remaining on trees – even to the end of November. Fruits were noted on the trees only in 2013. The differences in timing and duration of Callery pear phenophases from year to year, between sites and cultivars are pointed out and discussed.
