The characterization of the wood behavior at the tissue scale is still scarcely explored compared with the macroscopic scale, especially for shear. This work focuses on the mechanical properties of tissue samples of Norway spruce (Picea abies). Tensile and shear tests were conducted in different anatomical directions and relative humidity (RH) leve...

Half of the Amazon Forest, which has a marked seasonality in rainfall, is susceptible to intense droughts caused by positive phases of the El Niño-Southern Oscillation (ENSO). Cedrela odorata L., sensitive to climate variations, emerges as a promising candidate for studies on how trees respond to climate change. Given the demand for its wood and th...

The dependence of the width of annual rings of woody plants on the characteristics of the snow cover is analyzed in various natural zones of the West Siberian Plain and adjacent mountainous areas: the maximum depth and water reserve for the entire winter period and for individual months, the dates of disappearing, establishment, and duration of the...

In tropical and subtropical regions, much research is still required to explore the dendrochronological potential of their trees. This study aims to evaluate the anatomical structure and dendrochronological potential of three Mediterranean desert shrubs in Egypt (Lycium schweinfurthii var. schweinfurthii, L. europaeum, and Calligonum polygonoides s...

PREMISE: Dominant in many ecosystems around the world, clonal plants can reach considerable ages and sizes. Due to their modular growth patterns, individual clonal plants (genets) can consist of many subunits (ramets). Since single ramets do not reflect the actual age of genets, the ratio between genet size (radius) and longitudinal annual growth r...

Seasonal phenology is expressed in the annual rhythms of growth and quiescence, which may range from being sharply defined to weakly quantitative. These rhythms, both vegetative and reproductive, are a key aspect of a plant’s survival strategy. They enable the plant to both survive seasonal stresses and take advantage of favourable conditions, whil...

This study aims to compare the δ13C isotopic signal between bulk wood and α-cellulose in wood samples from the main trunk of Vitis vinifera L. to verify whether α-cellulose extraction is necessary for ecophysiological studies in this species. A pool of samples from different cultivars and provenances was analysed. The wood samples were obtained fro...

Abstract Introduction: Geomorphological processes, such as flash floods, affect the natural growth of trees. From the dating of disturbances in growth rings, historical events useful for the prevention and mitigation of natural hazards were reconstructed. Objectives: To determine the dendrogeomorphological potential of Pinus ponderosa Douglas ex C....

Abstract Introduction: Annual variation in growth ring characteristics has an impact on productivity and wood quality. Objective: To evaluate radial growth in two Pinus patula Schltdl. & Cham. plantations of different ages and thinning intensity, as well as its relationship to interannual variation in temperature and rainfall. Materials and methods...

Abstract Introduction: The evaluation of the effect of management activities on trees is essential to gain a better understanding of the processes occurring in the stands. Objective: To evaluate the effect of selection cutting on the growth of pine species in uneven-aged stands. Materials and methods: Thirty sampling sites were established in two m...
