Abstract To demonstrate the efficacy of vacuum pressure impregnation (VPI) with commercial wood preservative products to eliminate quarantine organism, pinewood nematode (PWN), Bursaphelenchus xylophilus , and other nematodes from maritime pine ( Pinus pinaster ) wood, in vitro assays industrial horizontal autoclave tanks were conducted. In nematicidal activity through direct exposure PWN 3rd-s...

This research was conducted in the west forest of Guilan, northern Iran. Data from various harvesting methods for 20 years were collected. Results showed that, productivity rate of round wood, pulp wood and fuel wood has had an upward trend, while rate of traditional products (lumber, sawn wood, charcoal, etc.) has had a downward trend. Production cost has been investigated in this research. Th...

Coating performance is greatly influenced by the properties of the wood substrate. This study was focused on evaluating the performance of coatings on both preservative- and thermally-treated wood. A number of commercially formulated semi-transparent stains Alkyd, Alkyd-Acrylic and PU were applied on four different types of preservative treated and heat-treated wood and their performances were ...

Stem cracks are becoming a major problem affecting timber quality and its economic value; their frequency may increase with increasing severity of drought stress due to climate change. Several conifer species affected, but such damage was mentioned for the first time in France hybrid larch (Larix x eurolepis) 1993. Even though link made severe some years ago, it believed, at that time, rapid gr...

in this research, the effect of tension wood formation in populus nigra on its anatomical characteristics was studied. vessel element and ray frequency (n/mm²), vessel diameter and ray dimensions were measured in both normal and tension wood. furthermore, the formation of gelatinous layer (g-layer) in the fibers of tension wood was studied. the results showed that the vessel proportion and diam...
