20.500.12556/RUL-69747 Variabilnost bioelektričnega potenciala dreves kot možnega kazalnika vpliva endogenih in eksogenih rastnih dejavnikov bukovih sestojih The variability of bioelectrical trees' potential as a possibile indicator of the influence of endogenous and exogenous growth factors in beech forest stands Proučena je variabilnost bioelektričnega potenciala dreves v enodobnih bukovih sestojih znotraj dreves in sestojev (po socialnih razredih in razvojnih fazah) in v mikrorastišču. Analizirani so vplivi endogenih (naravnega izločanja ter negovalnih ukrepov) in eksogenih - stresnih dejavnikov (zračna polucija, ekstremna suša) na bioelektrični potencial. Rezultati kažejo, da so bioelektrične meritve zelo občutljiv kazalnik pretekle rastnosti (življenjske moči) dreves, kot posledice dolgotrajnega vpliva endogenih dejavnikov in precej slabši kazalnik sedanje rastnosti (zdravstvenega stanja) kot posledice kratkotrajnih in trenutnih endogenih ali eksogenih stresov. The variability of the bioelectrical potential of trees in even-aged beech stands within trees and stands (by social classes and developmental phases) and in microsite bas been researched. The influences of endogenous (natural selection and tending measures) and exogenous - stress factors (air pollution, extreme drought) on the bioelectrical potential have been analysed. It has been proven by the results that bioelectrical measurements are a highly sensitive indicator of the past growth (vitality) of trees as the consequence of a long lasting influence of endogenous factors and a much worse indicator of the present growth (health condition) as the consequence of transitory and momentary endogenous or exogenous stresses.
