N2 - Changes in the lignin fraction of spruce and pine needle litter were followed by four different methods: Klason lignin, phloroglucinol lignin, dioxane-water-HCl-lignin and alkaline CuO oxidation. The decomposition patterns of the lignins studied were different, the largest differences between the methods being obtained for the spruce needles. Depending on the method used, between 36 and 46% of the original amount of lignin remained in the pine needles and about 30-61% in the spruce needles after 3 yr of decomposition. The decomposition rates of the various lignin pools were highly correlated with the loss in mass of the litter. The phloroglucinol lignin was decomposed significantly faster (P < 0.001) in the spruce needles than in the pine needles for as long as the decomposition process was followed. During decomposition of the litter, the residual amount of Klason lignin was correlated with the residual amounts of the other lignins. The application of the different methods to litter decomposition studies is discussed.
