Assessment of vegetative phenological phases of European beech (Fagus sylvatica L.) in relation to effective temperature during period of 1992–2008 in Czechia
2010
Abstract
The paper presents the results of long-term phenological observations of European beech (Fagus sylvatica L.) running in years 1992–2008 across the phenological network of the Czech Hydrometeorological Institute.The data assembled over this period were used for identification of timing of the following vegetative phenophases: bud burst (BBCH 07), first leaves 100% (BBCH 15), leaf colouring 10% (BBCH92), leaf fall 100% (BBCH 97).The vegetation season is getting longer. The totals of effective temperatures were used as a bio-climatological criterion for assessment of dependence of phenological phases on meteorological variables.
