Age trends and within-site effects in wood density and radial growth in Quercus faginea mature trees

Autor: Vicelina B. Sousa, José-Luís Louzada, Helena Pereira

Publikováno v: Forest Systems, Vol 25, Iss 1, Pp e053-e053 (2016)

Aim of the study: This paper aims to valorize the wood of Quercus faginea Lam. for high quality end uses (e.g. furniture) by studying growth and quality properties using mature trees. Age trends in tree-ring width and wood density are shown and the m

Quercus rotundifolia Lam., known as holm oak or evergreen oak, occurs naturally in the western Mediterranean region, mainly as part of the agroforestry or agrosilvopastoral systems in Portugal (“montado”) and Spain (“dehesa”), and is economic

Publikováno v: Physiology and Molecular Biology of Plants. 25:799-805

The Pinus nigra distribution in Portugal is restricted to six allochthonous populations with unknown origin and infraspecific taxonomy. This work intends to evaluate their genetic diversity, structure and relationships, and to infer about their infra

Wood anatomy holds relevant information for tree development and timber quality (e.g., wood density), which is important for the sustainability of the species. Quercus faginea Lam. (Portuguese or Lusitanian oak) is an autochthonous Mediterranean oak

Publikováno v: Materials & Design (1980-2015). 56:975-980

The variation of wood density and mechanical properties with site, tree and within tree (longitudinal and radial) were studied for blackwood (Acacia melanoxylon R. Br.) grown in four sites in Portugal. Twenty trees were randomly selected (40 cm dbh c

Impact of solar activity on the growth of pine trees: case study

Autor: José Luís Louzada, Vladimír Karlovský, José Carlos Rodrigues, Ivan Dorotovič

Publikováno v: European Journal of Forest Research. 133:639-648

In this work, we focus on the analysis of data for the ring width of two pine tree species: samples of six maritime pines (Pinus pinaster), grown in the north of Portugal, and one sample of Scots pine (Pinus sylvestris), grown in the south of Slovaki

Early assessment of density features for 19 Eucalyptus species using X-ray microdensitometry in a perspective of potential biomass production

Autor: Helena Pereira, José-Luís Louzada, Sofia Knapic, M. Pirralho

Publikováno v: Wood Science and Technology. 48:37-49

Eucalyptus plantations have been considered for bioenergy production and hence their biological characteristics that make them amenable to intensive short-rotation forestry. Wood density is an important parameter that directly affects fuel production

Variation in wood density and ring width in Acacia melanoxylon at four sites in Portugal

Autor: Helena Pereira, Fátima Tavares, José Luís Louzada

Publikováno v: European Journal of Forest Research. 133:31-39

The radial variation in wood density in Acacia melanoxylon R. Br. was studied using microdensitometry by sampling 20 trees with a 40-cm diameter class at four sites in Portugal. The measurements were taken from pith to bark at breast height. A. melan
