Shifts in flowering phenology of some plant species in the surroundings of Kokshetau city

Abstract

Over the last 30-45 years, changes in some characteristics of climatic factors have been observed in the Akmola
region (increase in average annual temperature, rainfall, etc.). Seasonality of biological phenomena, phenology, is directly
dependent on such changes. In the course of studies conducted in the last decade of September 2013, 2016 and 2018, in the
area surrounding Kokshetau city, 37 species of flowering wild plants were found, flowering of most of which were not typical
of this period. In 70% of the detected flowering plants, significant shifts in flowering phenology were observed, and in some
species, re-flowering was observed. There have also been registered cases of increased flowering time. The article discusses the
relationship between shifts in the phenology of flowering of some wild plant species with climatic factors.
