Physics and anatomy
Position and role of tension wood in trees - Case study: Eucalypts

Nooshin Toghraie

Volume 31, Summer 2 , May 2016, , Pages 237-247

https://doi.org/10.22092/ijwpr.2016.105772

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 More

Pulp and paper
Investigation of Properties of paper made from tensile wood and normal wood in Populus nigra

Jaber Hossein zade; Ali Abdolkhani; Mohammad Emami nasab; Hamid Khodabandeh lo; Mohammad Ahmadi

Volume 30, WINTER 4 , December 2015, , Pages 653-661

https://doi.org/10.22092/ijwpr.2015.101564

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 ...  Read More

Possibility of using non-destructive spectrophotometery to detect the poplar tension wood and spruce compression wood in freshly cut and dried timbers

Zinab Frozan; Asghar Taremian; Janin Gerar

Volume 27, WINTER 4 , December 2012, , Pages 568-753

https://doi.org/10.22092/ijwpr.2012.109599

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 More

Mohammad ali Sadat nia; Ali akbar Enayati; Loeic Brancheriau; Kambiz Pourtahmasi; Farhang Honarparvar

Volume 27, Issue 2 , June 2012, , Pages 306-318

https://doi.org/10.22092/ijwpr.2012.117069

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 ...  Read More

The effect of drying intensity and moisture content on longitudinal permeability of poplar tension and normal wood (populus nigra )

Mohammad mehdi Parhizkari; asghar tarmian; Hamid Reza Taghiyari; Alinaghi Karimi

Volume 26, Issue 3 , September 2011, , Pages 477-485

https://doi.org/10.22092/ijwpr.2011.117207

Abstract
  The longitudinal gas permeability of tension wood and normal wood of Populus nigra dried by two different drying conditions was measured. Board specimens were dried under mild conditions (50ºC, and ٪63 relative humidity) to reach ٪11.8 MC, and under severe conditions (62ºC, and ٪35 RH) to ...  Read More
