The increasing occurrence of dry and hot summers generates chronic water deficits that negatively affect tree radial growth. This phenomenon has been widely studied in natural stands native species but not commercial plantations exotic species. In central Chile, where the is increasingly planted, dynamics stone pine (Pinus pinea L.) growth under drought have little explored. We impact on four growing Chile. sampled cross-dated a total 112 trees from sites, measured their tree-ring width (RWL) series, obtained detrended series ring indices (RWIs). Then, we calculated three resilience during years (Rt, resistance; Rc, recovery; Rs, resilience), correlations between RWI seasonal climate variables. found lowest rate (1.94 mm) driest site (Peñuelas). Wet conditions previous winter current spring favored wettest (Pastene), rates were high (4.87 also increased response to thermal amplitude. Overall, fast-growing less resilient than slow-growing trees. Drought reduced stem affected hydric deficit. At stand level, resistance driven by precipitation. Fast-growing more resistant showed capacity recover after drought. general, post-drought due recovery events. fact non-native habitats, opens new perspectives for cropping, revealing it possible explore areas establish conclude shows good acclimation non-native, seasonally environments.
