Comparison of height growth strategies of Grecian fir (Abies cephalonica) and Atlas cedar (Cedrus atlantica).
Height increment data were assessed in 1980-85 on 3 sites in Var and Hérault, S. France. Trees were planted in 1970-71; for A. cephalonica, 11 Greek and 1 Italian provenances; for C. atlantica, 1 French provenance. Cumulative total height curve for C. atlantica was linear (excluding site variables); in contrast, A. cephalonica exhibited an increase in height growth rate at age 15-16 years. In a comparison of mean annual height increments between sites, C. atlantica increments exhibited greater variation than those of A. cephalonica. Results are discussed in relation to the 'free' height growth of C. atlantica, as compared with the more 'fixed' height growth of A. cephalonica which was relatively independent, for all provenances, of site factors.
