Morphological and anatomical changes of Norway spruce needles (Picea abies (L.)Karst.) in the Šoštanj steam power plant influence area

Kmecl, Alenka (author), Batič, Franc (author)

Morphological and anatomical changes of Norway spruce needles from 16 sampling plots in the vicinity of the Steam Power Plant in Šoštanj (TEŠ) were examined. The visible needle injuries were analysed and compared to the sulphur contents in the same samples. On the basis of this comparison and analysis of needle infections by microorganisms a conclusion was made on the possible causes of needle injuries. A new method of evaluation of needle injuries was tested. The method was based on autofluorescence of chlorophyll in spruce needles. After DCMU treatment of needle samples, the fluorescence intensity rose significantly, yet not proportionally to the autofluorescence intensity. The difference between the autofluorescence and the secondary fluorescence intensity (after DCMU treatment) showed, to which degree was damaged the photosynthetic apparatus of the Norway spruce-needles.

Abstract

Ugotavljali smo morfološke in anatomske spremembe smrekovih iglic s 16 vzorčnih mest v okolici TEŠ. Poškodovanost iglic smo primerjali z vsebnostjo žvepla v istih vzorcih. Na podlagi omenjene primerjave in analize okuženosti iglic z mikroorganizmi smo sklepali o izvoru njihovih poškodb. Preizkusili smo novo metodo vrednotenja poškodovanosti iglic na osnovi avtofluorescence klorofila v njih. Po dodatku DCMU se je fluorescenca močno povečala, vendar ne sorazmerno z avtoflorescenco. Razlika v intenzivnosti avtofluorescence in sekundarne fluorescence pokaže, v kolikšni meri je poškodovan fotosintetski aparat pri rastlini.
