Variación del Habito y Hábitat de Nothofagus antarctica en el Centro Sur de Chile

Abstract

The phenotypic variation presented by Nothofagus antarctica was studied in different habitats in the provinces of Cautín, Valdivia and Osorno, in Southern Chile. Eleven plots were located, 3 at the Andes, 2 at the Central valley and 6 at the coastal mountain Range. A significant floristic and edaphic variation among places was verified. By using morphological and population features of the species and stand edaphic characteristics by means of cluster and factorial analysis, 3 morphotypes were established: an arboreal one, growing in optimal environment, a camephytic one of bog-lands and an intermediate morphotype wich represents a shrubby dwarf type.
