Occurrence of circular vessels above axillary buds in stems of woody plants

Zygmunt Hejnowicz, Ewa U. Kuczyńska

Abstract


The circular vessels generally occur in intact wood stems just above the axillary buds. In this region the cell arrangement with vortices occurs. We interprete the circular vessels as the result of circular polarity in the cambial zone of the region above the axillary bud. The stability of circular polarity in this region is based on the vorticity of the cambium cells arrangement.

Keywords


circular vessel; circular polarity
