Influencia de las condiciones fisiográficas en la resistencia a helada del Eucalyptus globulus en Galicia

Eucalyptus globulus differential frost resistance index estimated using the HALLAM & TIBBITS (1988) method modified by BARA & cols. (1992) are analyzed in Galicia. The sampling has been located in 8 different topographic areas distributed in the" altitudinal band occupied' by the species in Galicia. Results show significative differences do to location and their interaction with the altitude indicating one selection within the species in frost resistance to the environmental pressure. K. W.: Eucalyptus globulus, Frost resistance, Conductivity, Frost.
