Journal ArticleDOI
Mesoporosity as a new parameter for understanding tension stress generation in trees
Shan-Shan Chang,Shan-Shan Chang,Bruno Clair,Julien Ruelle,Jacques Beauchêne,Francesco Di Renzo,Françoise Quignard,Guang-Jie Zhao,Hiroyuki Yamamoto,Joseph Gril +9 more
TL;DR: Measurements show that mesoporosity is high in tension wood with a typical thick G-layer while it is much less with a thinner G- layer, sometimes no more than normal wood.
Journal ArticleDOI
Tension wood and opposite wood in 21 tropical rain forest species : 1. Occurence and efficiency of the G-layer
TL;DR: 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 and showed that the G-layer is not a key factor in the production of high tensile stressed wood.
Journal ArticleDOI
Tension wood and opposite wood in 21 tropical rain forest species 2. Comparison of some anatomical and ultrastructural criteria
TL;DR: In this article, the anatomy of tension wood and opposite wood was compared in 21 tropical rain forest trees from 21 species belonging to 18 families from French Guyana and they observed a decrease in the frequency of vessels in the tension wood in all the trees studied.
Journal ArticleDOI
Relationship between growth stress, mechanical-physical properties and proportion of fibre with gelatinous layer in chestnut (Castanea sativa Mill.)
TL;DR: In this article, a range of mechanical and physical properties were determined for 96 specimens of chestnut wood and for wood types ranging from compression to tension wood; tests included growth stress, longitudinal Young's modulus in green and air-dried states, shrinkage in longitudinal and tangential directions.
Journal ArticleDOI
Wood specific gravity and anatomy of branches and roots in 113 Amazonian rainforest tree species across environmental gradients
Claire Fortunel,Julien Ruelle,Jacques Beauchêne,Paul V. A. Fine,Christopher Baraloto,Christopher Baraloto +5 more
TL;DR: It is concluded that tropical trees can invest differently in support and transport to respond to environmental conditions, and biophysical explanations should receive more attention.
