Distribution of Vessels in Tension Wood and Its Correlation with Lignin Composition

open access: yesJurnal Ilmu Kehutanan, 2019
The anatomical properties of tension wood were investigated for number and diameter of vessel and its correlation with lignin composition. Reaction wood sample was taken from the leaning stem of mindi (Melia azedarach).

Comparison of tension wood and normal wood for oxidative nanofibrillation and network characteristics [PDF]

open access: yesCellulose, 2020
AbstractCellulose nanofibrils (CNFs) are top-down nanomaterials obtainable from abundant lignocelluloses. Despite recent advances in processing technologies, the effects of variations in the lignocellulose structure and composition on CNF isolation and properties are poorly understood. In this study, we compared the isolation of CNFs from tension wood (

Investigation of Properties of paper made from tensile wood and normal wood in Populus nigra [PDF]

open access: yesتحقیقات علوم چوب و کاغذ ایران, 2015
In this research Tension Wood (TW) and Normal Wood (NW) of Poplar were analyzed for pulp production using Kraft pulping process. After preparing samples, Biometric characteristics of the NW and TW fibers were measured and samples were converted to pulp ...

Structural Characteristics of Reaction Tissue in Plants

open access: yesPlants, 2023
To maintain or adjust posture under the challenges of gravity and increased self-weight, or the effects of light, snow, and slope, plants have the ability to develop a special type of tissue called reaction tissue.

The influence of initial tension on blunting of chain saw blades and cutting efficiency

open access: yesLeśne Prace Badawcze, 2018
The initial tension of the chainsaw is a decisive factor in making the operator’s work more efficient and at the same time it is a parameter that the operator can adjust and thus affect significantly.

Tension Wood and Opposite Wood in 21 Tropical Rain Forest Species [PDF]

open access: yesIAWA Journal, 2006
Wood samples were taken from the upper and lower sides of 21 naturally tilted trees from 18 families of angiosperms in the tropical rain forest in French Guyana. The measurement of growth stresses ensured that the two samples were taken from wood tissues in a different mechanical state: highly tensile stressed wood on the upper side, called tension ...

Precautions for the Structural Analysis of the Gelatinous Layer in Tension Wood [PDF]

open access: yesIAWA Journal, 2005
The gelatinous layer (G-layer) of tension wood fibres in hardwood contributes to the mechanical function of the living tree and has significant consequences on properties of solid wood. Its size, shape and structure observed by optical or electron microscopy exhibits characteristic anatomical features.
