Indoleacetic acid (IAA) stimulated the incorporation of sugar into walls of cambial derivatives of Populus deltoides Bartr. trees, but not into those of Pinus sylvestris L. Extracts of cambium and cambial derivatives from both species contained a substance similar to IAA in chromatographic characteristics and growth promotion of wheat coleoptiles. Cambial derivative cells of both species accumulated IAA rapidly in uptake experiments, but the metabolic products of IAA were different. It is suggested that the differences in response to IAA in terms of cell wall synthesis may be related to reaction wood formation.
