Position and role of tension wood in trees - Case study: Eucalypts
Volume 31, Summer 2 , May 2016, , Pages 237-247
Abstract
One-year seedlings of five species of eucalypt: E. camaldulensis, E. microtheca, E. viminalis, E. globulus and E. gunnii were treated for 14 weeks in growth season, tilting a branch to c. 60° in every successful ones. We investigated the anatomical features of stems wood after 15 days and every 2 ... Read MoreInvestigation of Properties of paper made from tensile wood and normal wood in Populus nigra
Volume 30, WINTER 4 , December 2015, , Pages 653-661
Abstract
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. Pulp hand sheets mechanical and physical properties ...

Volume 27, WINTER 4 , December 2012, , Pages 568-753
Abstract
In this study, the potential use of spectrophotometery and CIELAB technique was evaluated to detect reaction woods, including poplar tension wood and spruce compression wood. Thus, two trees of spruce ( Picea abies) and poplar (Populous nigra) containing reaction wood were cut from a forest belonging ... Read MoreInvestigation the acoustic behavior of poplar and spruce species reaction wood using ultrasonic technique
Volume 27, Issue 2 , June 2012, , Pages 306-318
Abstract
The acoustic behavior of reaction and normal woods, phase velocity, group velocity and attenuation coefficients in the main directions for two wood species (Populus deltoids & Picea abies), were measured and compared. The results did not show any significant difference between phase velocities of ...
