Cambial activity and wood formation of maritime pine in a drought-prone environment: the effect of growth rate, size and climate

 

The formation of tree rings is a slow and complex process. The year-to-year climatic variability and the constant interaction between the internal and external factors controlling cambial activity create the conditions that make each tree ring unique. In order to capture the dynamics of cambial activity and wood formation during the growing season, it is necessary to monitor wood development in narrower time intervals (from minutes to weeks). Most of the studies performed on cambial activity and wood formation were held in cold environments, however, in other environments, such as drought-prone areas, it still remains poorly understood. In order to understand cambial activity and wood formation in a drought-prone environment, timings and dynamics of cambial activity were monitored in maritime pine (Pinus pinaster Ait.) growing in the Mediterranean region for two years (2010 and 2011). Anatomical observations of the cambial zone and differentiating xylem were made and stem radial increment monitored using manual and automatic dendrometers. The studies described in this thesis were carried out in Perimetro Florestal Dunas de Cantanhede, a managed plantation of maritime pine located in the west coast of Portugal.
