The molecular architecture distinctions between compression, opposite and normal wood of Pinus radiata [PDF]

open access: yesFrontiers in Plant Science
In gymnosperms compression wood is a specialised type of structural cell wall formed in response to biomechanical stresses. The differences in terms of gross structure, ultrastructure and chemistry are well-known.

Comparative studies on wood structure and microtensile properties between compression and opposite wood fibers of Chinese fir plantation [PDF]

open access: yesJournal of Wood Science, 2021
The microtensile properties of mechanically isolated compression wood (CW) and opposite wood (OW) tracheids of Chinese fir (Cunninghamia lanceolata) were investigated and discussed with respect to their structure. Major differences in the tensile modulus

Inter-Tracheid and Cross-Field Pitting in Compression Wood and Opposite Wood of Norway Spruce (Picea abies L.)

open access: yesNotulae Scientia Biologicae, 2011
Inter-tracheid and cross-filed pit specifications in compression wood and opposite wood of Norway spruce (Picea abies) were determined. Fewer pits of a smaller size and a smaller aperture diameter were observed in compression wood.

Transcript profiling of Populus tomentosa genes in normal, tension, and opposite wood by RNA-seq. [PDF]

open access: yesBMC Genomics, 2015
Wood formation affects the chemical and physical properties of wood, and thus affects its utility as a building material or a feedstock for biofuels, pulp and paper. To obtain genome-wide insights on the transcriptome changes and regulatory networks in wood formation, we used high-throughput RNA sequencing to characterize cDNA libraries of mature xylem

MODULUS OF ELASTICITY AND HARDNESS OF COMPRESSION AND OPPOSITE WOOD CELL WALLS OF MASSON PINE

open access: yesBioResources, 2012
Compression wood is commonly found in Masson pine. To evaluate the mechanical properties of the cell wall of Masson pine compression and opposite wood, nanoindentation was used. The results showed that the average values of hardness and cell wall modulus

Xylogenesis of compression and opposite wood in mountain pine at a Mediterranean treeline [PDF]

open access: yesAnnals of Forest Science, 2018
AbstractKey messageComparisons between compression and opposite wood formation in prostratingPinus mugoindicate that the secondary meristem can produce more tracheids with thicker walls by also increasing the number of contemporaneously differentiating cells, rather than only increasing the duration or the rate of cell formation.ContextAlthough cambium

A Comparative Study on Quantitative Anatomical Characteristics of Compression, Lateral, and Opposite Woods in Agathis loranthifolia and Pinus merkusii

open access: yesBioResources, 2023
Quantitative anatomical characteristics and their radial variation in compression (COW), lateral (LAW), and opposite (OPW) woods of Agathis loranthifolia and Pinus merkusii stem woods growing in Indonesia were observed and compared to understand wood ...

INTER-TRACHEID AND CROSS-FIELD PITTING IN COMPRESSION AND OPPOSITE WOOD OF

open access: yesBioResources, 2009
Inter-tracheid and cross-filed pit pairs in compression and opposite wood of Norway spruce (Picea abies) were examined. The size, appearance, and frequency of bordered pits on the radial side of axial tracheids and their aperture specification were ...
