Sap flow of birch and Norway spruce during the European heat and drought in summer 2003

Popis výsledku v původním jazyce

In this study the hydrological regime of Norway spruce (Picea abies) and birch (Betula pendula) growing on heavy soils in the south east of Austria was analysed. Results from the year 2003 characterised by an extremely hot and dry summer are presented inthis paper. Due to the extreme weather conditions the soil water content in August 2003 was very low (0.10-0.25 m3m-3) in the topsoil (0-50 cm) with practically no difference between both tree species. Sap flow was measured in eleven trees of each of both tree species using the heat field deformation (HFD) method. Only the qualitative variability of sap flow was analyzed so that data of sap flow per section (SFS) were used. The SFS of the birch trees was about three times higher than that of the sprucetrees. In June 2003 the daily SFS of the birch trees averaged 0.87 kg/cm and of the spruce trees 0.23 kg/cm. Due to the continuing drought in August 2003 these values were reduced to 0.39 kg/cm and 0.11 kg/cm respectively. A comparison o
