GOMEZ-TEJERO, Joaquín; DE LOS SANTOS-POSADAS, Héctor M.; FIERROS-GONZALEZ, Aurelio M.  e  VALDEZ-LAZALDE, J. René. Dominant height growth models for Eucalyptus grandis Hill ex Maiden and E. urophylla S. T. Blake in Oaxaca, México. Rev. fitotec. mex [online]. 2009, vol.32, n.2, pp.161-169. ISSN 0187-7380.

A series of site index families based on the Schumacher and Hossfeld IV models were fitted through ordinary least squares on data from fast-growing plantations of Eucalyptus grandis and E. urophylla on southeastern México. Data from the first re-measurement were used to validate dominant-height predictions based on the several site index families derived from Schumacher and Hossfeld IV. For E. grandis the dominant height predictions based on the anamorphic Hossfeld IV family proved to be the most efficient, meanwhile for E. urophylla the Hossfeld IV polymorphic 1 proved to be the best predicting family.
