The climatological signal in tree-rings of beech trees (Fagus sylvatica L.) from Beskid Wyspowy

摘要

Increment cores form European beech (Fagus sylvatica L.) trees were collected in two stands growing on the slopes of southern and northern expositions. The widths of tree-rings were measured. The air temperature and atmospheric precipitation were found to have similar impact on tree-ring widths for most trees. Wet July and warm and dry autumn of the year prior to annual ring formation, as well as worm winter and summer of the year the ring was formed had positive effect on the radial growth. Dry and cold August of the previous year and dry June of the current growing season also positively affected the radial increment. Non-meteorological factors Disturbed the rhythm of annual change sin radial increment of the trees under study modified mainly by thermal And pluvial conditions in the months before and after the growing season.
