Ecophysiological research of European beech (Fagus sylvatica L.) in high-productive mixed forests of the Poľana Mts in Central Slovakia

Abstract

This paper presents the results of ecophysiological research of European beech (Fagus sylvatica L.) in high-
productive mixed forests of the Slovak Poľana Mountain. This research was performed in the research and
demonstration object Poľana - Hukavský grúň. The radiation, temperature and humidity regimes, as well as
daily dynamic of photosynthetic activity and electric resistance of cambial tissue are presented within the
whole beech crown profile. The impact of meteorological conditions on selected physiological processes
was studied. The results confirmed close correlation between a diameter of trees d 1,3 and biofield, as well as
between a biofield and cambial tissue’s electric resistance. The considerable differences in CO 2 uptake within
individual beech crown layers were determined.
