Welding of thermally modified hornbeam [PDF]

open access: yesDrvna Industrija, 2009
Welding of dowels in the base is carried out by technology of rotation welding. During welding, a physical-chemical process takes place as a result of mechanical friction because of dowel rotation and impression into the static base with the set ...

Study of different height-diameter models for hornbeam (Carpinus betulus L.) in uneven-aged stands of Shastkalateh forest of Gorgan [PDF]

open access: yesتحقیقات جنگل و صنوبر ایران, 2016
Projection of stand development over time relies on accurate height-diameter functions. In this study, we evaluated the capability of 18 nonlinear models to estimate hornbeam heights in a portion Shastkalateh experimental forest in Gorgan, Golestan ...

Plastomes of nine hornbeams and phylogenetic implications [PDF]

open access: yesEcology and Evolution, 2018
AbstractPoor phylogenetic resolution and inconsistency of gene trees are major complications when attempting to construct trees of life for various groups of organisms. In this study, we addressed these issues in analyses of the genus Carpinus (hornbeams) of the Betulaceae.

Quantity and quality of deadwood in the mid-successional stage in oriental Beech (Fagus orientalis Lipsky) stands (Case study: Kheyrood forest, Nowshahr) [PDF]

open access: yesتحقیقات جنگل و صنوبر ایران, 2016
Deadwood is widely recog­nized as an extremely important structural and functional component of forest communities. Therefore, understanding its role and dynamics are important to improve forest management strategies in both managed and unmanaged forests.

A chromosome-level reference genome of the hornbeam, Carpinus fangiana [PDF]

open access: yesScientific Data, 2020
AbstractBetulaceae, the birch family, comprises six living genera and over 160 species, many of which are economically valuable. To deepen our knowledge of Betulaceae species, we have sequenced the genome of a hornbeam, Carpinus fangiana, which belongs to the most species-rich genus of the Betulaceae subfamily Coryloideae.
