Abstract

Having analyzed the climate changes in the area of Kyiv for the period of the research 2009-2013 and based of comparative analysis of seasonal development of beautiful flowering shrubs, our own observations and data of other authors, the dynamic for 60 years in flowering phases of the species which are the most common in landscape gardening was revealed. The substantial impact of climate changes to flowering phases of woody plants was proved.

 

Based on numerous hydrometeorological features and data, national specialists-climatologists point out that for the last 10-25 years the features of new climate started forming in Ukraine.

Global climate changes have significant impact on plant life. It leads to the shift of phenological phases of vegetative development of plants, changes of genetic composition of plant life, change of species composition of alien species due to weakening of adaptive capability of native flora. The most vulnerable are woody plants as those that have the longest life cycle.

According to the results of the inventory in 100 parks of the city of Kyiv for the period 2009-2011, the plants in the city areas of public use are represented by 20 species of beautiful flowering shrubs among which the most common are only 9 species.

According to the revealed dependence of beginning of the flowering phase of beautiful flowering shrubs on climatic indexes in the area of Kyiv, due to warming of climate the essential shifts of phenological phase of beginning of flowering to more earlier stage are observed in the area of research, while the amount of effective temperatures remains constant for each particular species.
