UNDERSTORY STRUCTURE AND FUNCTION FOLLOWING RELEASE FROM CATTLE GRAZING AND OVERSTORY THINNING IN MEDITERRANEAN CONIFER PLANTATIONS

  Cattle grazing and overstory cover restrict understory growth and interact in shaping the understory community structure in Mediterranean conifer plantations.     Abstract Understanding how silvicultural manipulations drive understory structure and function in Mediterranean pine plantations

Forward selection in a maritime pine polycross progeny trial using pedigree reconstruction

Molecular markers were used for paternity recovery in a maritime pine (Pinus pinaster Ait.) polycross trial, facilitating forward selection. Different breeding strategies for seed orchard establishment were evaluated by comparing genetic gains and diversity. This work opens

Modelling wood formation and structure: power and limits of a morphogenetic gradient in controlling xylem cell proliferation and growth

The emergence of the characteristic tree-ring pattern during xylogenesis is commonly thought to be controlled by a gradient of morphogen (auxin, TDIF peptide…). We show that this hypothesis accounts for several developmental aspects of wood formation, but

Changes of secondary metabolites in Pinus sylvestris L. needles under increasing soil water deficit

A multiphasic response to water deficit was found in Scots pine primary and secondary metabolism. First, an increase of terpenoids coincided with the stomatal closure. Second, an accumulation of proline, ABA, and shikimic acid was detected when

Improving the utility, performance, and durability of wood- and bio-based composites

This paper briefly reviews the state of the art in various types of wood- and bio-based composites, summarizes recent advances, and then discusses future possibilities for improving the durability of wood- and bio-based composites. Abstract Wood can

INDEPENDENT LINES OF EVIDENCE OF A GENETIC RELATIONSHIP BETWEEN ACOUSTIC WAVE VELOCITY AND KRAFT PULP YIELD IN EUCALYPTUS GLOBULUS

  Multiple lines of evidence suggest acoustic wave velocity (AWV) would provide a rapid and efficient method to indirectly select for superior pulp yield in Eucalyptus globulus breeding programs.   Abstract Eucalyptus globulus is one of the

ACOUSTIC EVALUATION OF LOBLOLLY PINE TREE- AND LUMBER-LENGTH LOGS ALLOWS FOR SEGREGATION OF LUMBER MODULUS OF ELASTICITY, NOT FOR MODULUS OF RUPTURE

Loblolly pine (Pinus taeda) logs can be evaluated using acoustic velocity whereby threshold acoustic velocity values can be set to ensure lumber meets specified mechanical property design values for modulus of elasticity   Abstract There is a

Mortality, re-sprouting vigor and physiology of coppice stumps after mechanized cutting

Mechanized cutting may result in higher stump damage levels, especially if cutting is performed with shears. Nevertheless, stumps cut with mechanized technology do not show higher mortality rates than do stumps cut manually with a chainsaw. One-year

Site factors as predictors for Pinus halepensis Mill. productivity in Spanish plantations

This work presents a discriminant model to predict Pinus halepensis forest productivity using parameters related to water availability (Annual Hydric Index, soil porosity and slope) and information about the N immobilization by soil microorganisms (microbial biomass N).
