Abstract

In the paper, potential analysis of various growth parameters of Norway spruceare introduced at the macro and micro levels. Dendroecological measurements give information as to xylem growth ring widths, their density and content of stable isotopes in the xylem growth rings. Needle trace method of the terminal annual shoot allows retrospective view into needle density ofthe terminal annual shoot and consequently reconstruction of the several parameters linked to the needles and air pollution. Using pinning method, it is possible to follow intra-annual dynamics of the radial growth of trees at the cellular level and furthermore investigate the effect of climatic factorson cambial activity. V prispevku so predstavljene možnosti analize različnih rastnih parametrov navadne smreke na makro in mikro nivoju. Dendroekološke meritve nam dajo informacijo o širinah branik, gostotah branik in vsebnosti stabilnih izotopov ogljika v njih na nivoju branike ter jih retrospektivno povezati z različnimi okoljskimi informacijami. Metoda preučevanja sledi iglic terminalnega poganjkanam omogoča rekonstrukcijo gostote iglic terminalnega poganjka in posledično analizo številnih parametrov, vezanih na iglice in zračno polucijo.Z metodo pinning je mogoče slediti intraanualno dinamiko debelinske rasti drevesa na celičnem nivoju in nadalje raziskati vpliv klimatskih dejavnikov na kambijevo aktivnost.
