In 1993-02 relationship between air temperature and phenology the beginning of vegetation and blooming period was investigated in Wroclaw area (Poland). Linear correlation coefficient between first leaf appearance and the beginning of blooming was significant. The number of warm days (greater 10 deg C) in the 3rd decade of March affected the length of blooming period and significantly increased pollination. During flowering the number of days with temperature over 5 and 10 deg C also prolonged the blooming period, however increased number of warm days (greater 15 deg C) shortend the end of blooming phase
