S. Smidt et al., ALTITUDE-DEPENDENT OZONE CONCENTRATIONS AND CHANGES OF OZONE-RELATED PLANT-PHYSIOLOGICAL PARAMETERS IN THE NEEDLES OF NORWAY SPRUCE, Proceedings of the Royal Society of Edinburgh. Section B: Biological sciences, 102, 1994, pp. 113-117
Two interdisciplinary projects of the Federal Forest Research Centre h
ave been started in the last ten years as a contribution to the Austri
an forest ecosystem research programme. Their main goal was an interdi
sciplinary investigation of interactions between air pollutants and va
rious ecological parameters. Plant/physiological parameters were used
to describe the naturally and anthropogenically induced stress pattern
s caused by different environmental conditions. Biochemical analyses o
f needles of Norway spruce (Picea abies) including ascorbic acid conce
ntrations, peroxidase activity, thiols and pigments were taken at two
altitudinal profiles.
