Quantitative wood anatomy analyzes the variability of xylem anatomical features in trees, shrubs, and herbaceous species to address research questions related to plant functioning, growth, and environment. Among the more frequently considered anatomical features are lumen dimensions and wall thickness of conducting cells, fibers, and several ray properties. The structural properties of each xylem anatomical feature are mostly fixed once they are formed, and define to a large extent its… Expand
Functional Relationships of Wood Anatomical Traits in Norway Spruce
TLDR
The results show that tree height significantly affects wood hydraulic traits, as well as number and tangential diameter of tracheids, and ultimately the total ring width, and the amount of earlywood and latewood percentage influence wood hydraulic safety and efficiency, aswell as mechanical traits.

Climatic influence on tree wood anatomy: a review
Wood anatomical traits of xylem are the characteristics of tree rings at cellular and subcellular scales providing important insights on structural features and their linkage to the environment.Expand
New research perspectives from a novel approach to quantify tracheid wall thickness
TLDR
Cell wall thickness measurements performed with a novel approach to measure tracheid CWT in high-resolution images of wood cross-sections showed comparable accuracy for several image resolutions, with an optimal accuracy-efficiency balance at 100× magnification. Expand
From xylogenesis to tree rings: wood traits to investigate tree response to environmental changes
TLDR
An overview of wood formation processes up to tree-ring development, bearing in mind that the combined action of intrinsic factors and environmental drivers determines the anatomical traits of a tree ring formed at a specific time and position within the tree’s architecture is provided. Expand
Anatomical features of Fagaceae wood statistically extracted by computer vision approaches: Some relationships with evolution
TLDR
This study applies two computer vision approaches to optical micrographs: the scale-invariant feature transform algorithm and connected-component labelling, which extract the shape and pore size information, respectively, statistically from the whole micro graphs, to enable the efficient detection of specific features of 18 species from the family Fagaceae.

Introducing anatomical techniques to subfossil wood
Abstract Successful cross-dating of subfossil wood, ideally in combination with precise information on germination and dieback, requires the accurate detection of tree-ring width (TRW) boundariesExpand

Retrospective Analysis of Wood Anatomical Traits Reveals a Recent Extension in Tree Cambial Activity in Two High-Elevation Conifers
TLDR
A novel retrospective approach is applied to test the long-term consistency in the timing of onset and ending of cambial activity, and in the maximum cambia cell division rate in two conifer species, European larch and Norway spruce at high-elevation in the Alps, to improve the understanding of tree responses to climate variability in both the short- and long- term context.

Xylem anatomical and growth responses of the dwarf shrub Vaccinium myrtillus to experimental CO2 enrichment and soil warming at treeline.
TLDR
The findings suggest that future higher atmospheric CO2 concentrations will have smaller effects on V. myrtillus growth and functioning than rising temperatures at high elevations; further, growth stimulation of this species under future warmer conditions may not be synchronized with xylem adjustments favouring hydraulic efficiency. Expand
How does climate influence xylem morphogenesis over the growing season? Insights from long-term intra-ring anatomy in Picea abies
TLDR
The distinct climate impacts on cell enlargement and wall thickening indicate that different morphogenetic mechanisms are responsible for different tracheid traits, and can support and extend short-term xylogenesis observations. Expand

TLDR
Evaluated rays in conifers and the presented guidelines regarding data accuracy as a function of measured wood surface and number of samples represent an important methodological reference for ray quantification, which will ultimately improve the understanding of the fundamental role of ray parenchyma tissue for the performance and survival of trees growing in stressed environments.

Variability of ray anatomy of Larixgmelinii along a forest productivity gradient in Siberia
TLDR
This study quantifies how anatomical properties of rays—one of the main container for carbon reserves in tree stems—vary among sites, individuals, and annual rings of Larix gmelinii growing in contrasting sites in Siberia and suggests that the functional connection between the anatomy of rays and tracheid is unaffected by environment.

TLDR
An automated image analysis system (Root Xylem Analysis System [ROXAS]) is developed to improve the standardization and efficiency of conventional herb‐chronological analysis and may prove to be useful for efficient and reproduced analysis of annual growth increments in the roots of forbs and for investigations into their functional root anatomy.
