      To determine the response of tree rings to climate, twenty cores were extracted from ten trees of Pinus pinea L. in Istanbul-Alemdag. A response function was used to characterize the relationships between tree rings and temperature and precipitation. The precipitation of the current year and the temperature at the beginning of the growing period have a significantly positive influence on the growth of the tree ring. Mean sensitivity was found to be 0.291, and it was concluded that Pinus pinea L. is a dendroclimatologically sensitive species.
