Xylogenesis of Pinus pinaster under Mediterranean climate: predicting tree growth facing climate change

The Mediterranean climate is expected to become warmer and drier. Understand how forests will coupe with such changes is extremely relevant. Xylem formation is a complex process partly controled by precipitation, temperature and photoperiod. Microcore sampling enables us to follow the genesis of wood rings "cell-by-cell", with the determination of the onset, duration and influence of climate in the process. We are studying the xylogenesis of P. pinaster growing under Mediterranean climate, in Perimetro Florestal Dunas de Cantanhede, in the northwest coast of Portugal. In parallel with the xylogenesis, radial incremet will also be studied using dendrometer bands and automatic dendrometers. With this study we hope to better understand wood formation in P. pinaster and the climate influence in the overall process, so that we will be able to predict growth responses to climate.
