Chestnut Wood in Compression Perpendicular to the Grain: Non-Destructive Correlations for Test Results in New and Old Wood [PDF]
Construction and Building Materials, 2007 Abstract This paper addresses the evaluation of the compressive properties of chestnut wood under compression perpendicular to the grain, using destructive and non-destructive methods. Three non-destructive methods (ultrasonic testing, Resistograph and Pilodyn) are proposed and the possibility of their application is discussed based on the ...

RESULTS OF EXPERIMENTS ON CHESTNUT CULTIVARS FOR WOOD PRODUCTION
Acta Horticulturae, 2010During 12 years research has been done on growth, architectural traits and cultivation techniques of some cultivars ('Cardaccio', 'Mozza', 'Politora', 'Perticaccio' and 'Mondistollo') traditionally cultivated in Central Italy for their high timber quality.

EPIPHYTIC LICHEN DIVERSITY IN CHESTNUT WOODS
Acta Horticulturae, 2010In the frame of a project for the evaluation of epiphytic lichen diversity in forests, we studied chestnut orchards. A random stratified sampling design based on climatic data was adopted for selecting sampling sites. Three circular plots were established in each of the four study sites for a total of 77 reference trees.

Wood–water relations of chestnut wood used for structural purposes
European Journal of Wood and Wood Products, 2012Hygroscopic properties and water vapour permeability of chestnut (Castanea sativa Mill.) wood were studied using saturated salt solutions, and the results were analyzed using the Hailwood–Horrobin model. At 20 °C/65 % the equilibrium moisture content (MCeq) and density were 11.5 ± 0.1 % and 576.6 ± 10.2 kg m−3, respectively, and the fiber saturation ...

Photochemical Colour Changes on Chestnut Wood Surface
2014The aim of this work is to study the surface colour and chemical modifications in chestnut wood samples as a consequence of irradiating in a controlled environment. The changes were investigated by reflectance spectrophotometry in a totally non-invasive modality, and further deepened by Fourier transform infrared spectroscopy and hyperspectral imaging,

Relationship between canker size and wood starch in American chestnut
European Journal of Forest Pathology, 1984AbstractChestnut trees (Castanca dentata) were wounded in May and inoculated with Cryphonectria parasitica. In August, canker area was measured and the surfaces of longitudinal dissections of stem wood were stained with I2KI to reveal the presence of starch. Sections with the most starch had smaller cankers than sections with no starch.

IN VITRO ANTIVIRAL ACTIVITY OF CHESTNUT AND QUEBRACHO WOOD EXTRACTS
2008Avian reovirus (ARV) and avian metapneumovirus (AMPV) were chosen for an in vitro antiviral screening of three Chestnut (Castanea spp.) wood extracts and a Quebracho (Schinopsis spp.) wood extract, all containing tannins. The MTT assay was used to evaluate the 50% cytotoxic compound concentration (CC50) on Vero cells.

Some physical properties of sweet chestnut wood grown in Greece
Holz als Roh- und Werkstoff, 1997Dises from twenty trees ofCastanea sativa Mill from two stands (Arnea and Morna) were taken at breast height, 5 m and the beginning of crown (crown base). These wood samples were examined for wood density, shrinkage and growth rate. Overall basic density was 0.486 g/cm3 on average at breast height, 0.522 g/cm3 at 5 m height and 0.542 g/cm3 at crown ...
