Callose in compression wood tracheids
Acta Societatis Botanicorum Poloniae, 2015 A study of 20 gymnospermous species has shown that in most of them callose occurs in the helical checks of the S2 layer of cell walls in the compression wood tracheids.

Mechanics of the Compression Wood Response [PDF]
Plant Physiology, 1973 A new method for simulation of cross-sectional growth provided detailed information on the location of normal wood and compression wood increments in two tilted white pine (Pinus strobus L.) leaders. These data were combined with data on stiffness, slope, and curvature changes over a 16-week period to make the mechanical analysis.

STUDYING SOME ANATOMICAL AND MECHANICAL CHARACTERISTICS OF COMPRESSION WOOD FOR Pinus brutia Ten. LEANING TREES [PDF]
Mesopotamia Journal of Agriculture, 2009 This study was conducted to show the effect of compression wood on some anatomical characteristics and mechanical characteristics of brutia pine Pinus brutia Ten. trees growing naturally at Dohuk provenance and to compare it with the standing trees (tree

Acta Societatis Botanicorum Poloniae, 2015 The corewood of pine ds very prone to compression wood formation, this changing the whole pattern of the tree ring structure and the siz.es of early and late wood. Compression wood always increases the formation of late wood at the expense of early wood.

Journal of Bioresources and Bioproducts, 2020 A test equipment was developed, which allows for real time observation of the deformation behavior of wood cellular structure under a compression load applied in radial direction. Compression tests were performed on jack pine (Pinus banksiana) and balsam
