Causes and criteria of resistancë to air pollution in Norway spruce. 3. Tolerance of toxic materials (“internal” resistance). Comparing relatively resistant and not resistant Norway spruce clones, an attempt was made to find differences by investigating the relation of needle colour and absorption of sulfur, needle pH‐value and buffer capacity, sulphur distribution within several of their needle components and within the total plant, the ratio of organically fixed sulfur to total sulfur content of noedles, and content of sulfhydril groups, protein and chlorophyll of needles. Significant differences were shown only in buffer capacity of unfumigated needles, and in thc propornon of organically fixed sulfur before and after SO 2 fumigation.
