Summary The relationship between the arrangement of cell events occurring in cambium in a definite configuration and the grain pattern of wood was investigated. Taking into consideration the growth activity of fusiform cell ends, a model of a migrating morphogenetic wave determining an event configuration was made. Waves of length λ=1 m for the periods T=2 years and T=3 years and waves of lengths λ=l m and λ=0.04 m for the period T=10 years were considered. On the model, events from successive annual rings, conventionally comprising 10 cell layers each, were summed. In this way, event maps were obtained. For wave λ=4 mm, the domain pattern on the modelled map was compatible with the grain pattern. The domain pattern for the wave λ=1 m was impossible to recreate because the wave “migrated too fast”. In this case, the pattern of event configuration, incompatible with the grain pattern, formed microareas, which were not domains.
