CORREIA, Isabel; ALMEIDA, Helena  e  AGUIAR, Alexandre. Variability of Growth and Form of 8 Years Provenances of Pinus pinaster in Mata Nacional do Escaroupim. Silva Lus. [online]. 2004, vol.12, n.2, pp.151-182. ISSN 0870-6352.

Maritime pine provenances were evaluated at age 8, in Mata Nacional do Escaroupim. The objective was to evaluate provenance variation, their performance related to adaptative characteristics, to growth and form, and estimation of genetic parameters. Significant performance differences were observed between the 30 provenances. At age 8, increments up to 10% in growth can be expected, when the best provenances are selected for plantations in sites similar to Escaroupim. Highland provenances show better form but smaller growth. Results will allow the selection of provenances for plantations under environmental conditions similar to Escaroupim and further selection of genotypes for improvement in well adapted provenances.
