ABSTRACT
The year 2014 brought a series of heat records in many countries in Europe. Higher than average mean temperature during summer season was observed also in Poland. The article presents the analysis of phenological phases observed in 2014 of chosen wild-plants in comparison with the same phases observed in earlier periods. Authors compared the results of fitophenological observations from the automatic station located in Trzebaw near Poznań with the observations which were conducted in the central Wielkopolska by the Institute of Meteorology and Water Management – National Research Institute in years 1946-1960 and 2007-2012. For the analysis 4 phenophases of 3 wild plants and BBCH main phases of winter triticale were chosen. In 2014, in 90% of analyzed cases, beginning of the wild plants phenophases was noticed earlier than in years 1946-1960, in 78% - earlier than in years 2007-2012 and phenophases of triticale appeared from several- to more than 20 days earlier than in years 1982-1996.
