RNA Sequencing Reveals Phenylpropanoid Biosynthesis Genes and Transcription Factors for Hevea brasiliensis Reaction Wood Formation [PDF]

Frontiers in Genetics, 2021
Given the importance of wood in many industrial applications, much research has focused on wood formation, especially lignin biosynthesis. However, the mechanisms governing the regulation of lignin biosynthesis in the rubber tree (Hevea brasiliensis ...

Initial Desorption of Reaction Beech Wood

Drvna Industrija, 2022
The research aimed to obtain empirical data for modeling the initial desorption in reaction wood from the cross-section of the green beech (Fagus sylvatica L.) log. Firstly, we analyzed the chemical composition, macro and microscopic structure of tension

Mechanical strength of reaction wood

Silva Fennica, 1977
According to the literature, the mechanical strength of the green reaction wood of softwood species (compression wood) is greater than that of normal wood. Drying increases the mechanical strength but less in reaction wood than in normal wood.

The Course of Mechanical Stress: Types, Perception, and Plant Response

Biology, 2023
Mechanical stimuli, together with the corresponding plant perception mechanisms and the finely tuned thigmomorphogenetic response, has been of scientific and practical interest since the mid-17th century.

Multiomics studies with co-transformation reveal microRNAs via miRNA-TF-mRNA network participating in wood formation in Hevea brasiliensis

Frontiers in Plant Science, 2023
IntroductionMicroRNAs (miRNAs) are small endogenous non-coding RNAs that play an important role in wood formation in plants. However, the significance of the link between miRNAs and their target transcripts in wood formation remains unclear in rubber ...

Formation of Annual Ring Eccentricity in Coarse Roots within the Root Cage of Pinus ponderosa Growing on Slopes

Plants, 2020
The coarse roots of Pinus ponderosa included in the cage are the ones most involved in tree stability. This study explored the variations in traits, such as volume, cross-sectional area, and radius length of cage roots, and used those data to develop a ...

Application of a strain gauge to assess drying stresses in normal and tension wood of corymbia citriodora

Maderas: Ciencia y Tecnología, 2022
The quantitative evaluation of longitudinal drying strain can provide relevant information for the processing wood and lumber industry, especially with regard to reaction wood in Corymbia, since little has been published.

The Nature of Reaction Wood [PDF]

Australian Journal of Biological Sciences, 1948
The structure of tension wood fibres is ofconsiderahle academic and practicalinterest, both in relation to considerations of the stimuli which produce them,and to studies of the influence of fibre structure on the properties of the wood asa whole. As is well known, the chief abnormal properties of tension wood lie inits unusually high longitudinal ...

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

تحقیقات علوم چوب و کاغذ ایران, 2012
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
