RAPD and freezing resistance in Eucalyptus globulus
Eucalyptus globulus is the second most important forest species in Chile, after Pinus radiata. The main advantages of E. globulus are its fast growth (25 m³/ha/year) and its excellent wood quality for kraft pulp production. On the negative side, its low freezing tolerance has been an obstacle for th...
