Abstract
The determination of the phytohormone abscisic acid (ABA) in needles of fir (Abies alba Mill.) is difficult due to the small amount of ABA and the large volume of phenolic and terpenoic compounds, which have similar structures compared with ABA. The quantitative analysis of ABA in purified extracts was not possible by HPLC because of deficient separation. A qualified method for exact quantification is gas chromatography using an electron capture detector. In this way ABA was completely separated from all other substances. Starting from the question, whether the content of secondary plant products of needles of Picea abies (L.) Karst. is influenced by damage, spruces from Wank Mountain were analysed. The needle concentrations of different compounds were influenced significantly by the class of damage as well as by the level of altitude. (orig.).
