The main objective of the Master's thesis is to collect and evaluate scientific information and processing datasets of expected impact of climate change and their relationship to distribution, growth and development of thermophilic fruit trees in the Czech Republic. The first and second parts of the literature research are focused on the impact of global warning and economic/agricultural conditions on growth and development of the thermophilic species of fruit trees at the global, regional and local levels. The next section deals with the relationship of thermophilic fruit trees production with climatic, soil conditions, phenology and economic factors, which greatly affect yields in the Czech Republic.
This study was conducted on daily meteorological variables (sum of global radiation, maximum and minimum temperatures) and annual yield datasets of Apricot (Armeniaca vulgaris) and Peach (Prunus Persica) trees at the country level for the period 2005-2015. The obtained new results can be divided into 3 parts: (1) catalogue of meteorological phenomena during the growing season, (2) catalogue of meteorological phenomena during the period of dormancy, and (3) statistical analyses of meteorological extreme events during flower/flowering formation of the Apricot and Peach trees.
Results based on the analysis of historical phenological observations and descriptive statistics of yield parameters of thermophilic fruit trees over the study period shown that (i) mainly spring phenological stages of the thermophilic fruit trees shown a tendency to an earlier onset, (ii) the highest variability in the phenophase onsets of Apricot and Peach are in the inflorescence emergence and beginning of flowering, (iii) the coefficients of variation were higher for Peach with year-to-year variations in crop yields, and (iv) Peach had the largest fluctuations in average annual production (from 0.48 to of 0.72 tha-1 year-1).
