Bioindication of Climate Development on the Basis of Long-Term Phenological Observation

Popis výsledku v původním jazyce

The aim of the study was to evaluate long-term observations of phenological phases "beginning of apricot flowering" (BAF). Further to establish the level of dependence between the BAF Velkopavlovická variety and selected meteorological elements in the period before apricot flowering. For the evaluation the phenological and meteorological data from Velké Pavlovice station of Czech Hydrometeorological Institute Brno branch was used. Evaluated was a data from the period 1940-2008. The average onset of BAF phenophase in the Velké Pavlovice (Czech Republic, Central Europe) was found 11th April, i.e. 101st day of the year. The earliest flower of apricot was 18th of March 2007, the latest 6th May 1957. Linear trend-line shows an earlier onset phenophase approximately 13 days, i.e. 2 days per decade. To quantify the apricot demands on heat before the flowering the sums of effective air temperature from 0 to 10 oC for varying lengths of the period before flowering were calculated. The relationship between the accumulated growing degree days (AGDD) and BAF was assessed using correlation coefficients. Observed correlation coefficients varied from -0.46 to 0.50, suggesting a relatively weak dependence between the BAF and test meteorological characteristics. In connection with the assumption that flowering trees may be affected by heating of buds due to solar radiation was also performed an evaluation of the duration of sunshine. Significant effect on the flowering apricot, applicable for predicting of the onset of phenological stage, was not established. Nevertheless, the air temperature plays an important role on onset of apricot flowering phenophase is not its clear indicator. Methods based on AGDD calculations are quite successfully used in particular for determining of onset phenophases following the flowering. Attempts to forecast of the onset of the first phenophases, bud development and BAF are not entirely successful.
