A Note on the Formation of Compression Wood Induced by Morphactin IT 3456 in Thuja Shoots

J. E. Phelps, E. A. McGinnes, M. Smoliński, M. Saniewski, Janina Pieniążek


Light and scanning electron microscopes were used to examine the structure of normal wood, naturally formed compression wood, and wood formed after and influenced by morphactin IT 3456 treatment in Thuja occidentalis L. lateral shoots. Morphactin strongly induced typical compression wood formation around those shoots. On the basis of these and prior data, a relationship apparently exists between morphactin treatment and the formation of compression wood in Coniferales.
