Resumen:
inus pinea is an interesting species especially for its fruit production, which depends upon vegetative growth. Growth of this species was analyzed along a climatic gradient in Chile, in all sites where it was planted in the last century. Three macrozones (MZs) located in the north, south and coastal range were identified according to height and DBH growth rates. We also examined growth in relation to several climatic variables (annual and seasonal temperatures, thermal oscillation, rainfall and a hydric index measuring water stress) and two cultural practices (irrigation and pruning). The relative contribution of each variable on growth measurements was assessed through regression trees and linear models. Growth of stone pine showed marked differences among the three MZs. In the South MZ, growth rate was the highest for height (0.35 m year−1 ) and DBH (1.50 cm year−1 ), whereas in the Dry Coast MZ, the species showed the lowest growth rate in height (0.23
