Natural durability of fast growth plantation Eucalyptus grandis Hill, ex Maiden
2008 - IRG/WP 08-10660
One of the fast growing species cultivated in Uruguay of mayor economical importance is Eucalyptus grandis. Physical and mechanical properties of juvenile and mature wood from different regions have been deeply studied. However, since no scientific data of natural durability of this specie has been reported, natural durability of E. grandis from two sites (Rivera and Rio Negro) was evaluated. Two ...

Natural durability and anatomical features of teak (Tectona grandis) from plantations in Costa Rica
2008 - IRG/WP 08-10671
Teak (Tectona grandis) possesses superior mechanical properties and durability and is thus frequently used as an alternative to impregnated timber in Europe. Demand on teak has resulted in severe exploitation of the tropical teak forests in recent decades, but today the imported timber originates mainly from plantations and is certificated according to the Forest Stewardship Council (FSC) policy. ...

Opportunities and Needs with Treatments for the Protection of Plantation Species
2008 - IRG/WP 08-40438
The future of the wood treating industry lies increasingly on the treatment of wood derived from plantation forests. Plantation softwoods and hardwoods both provide significant opportunity for utilization coupled with protection technologies, but development programs will require much more focus and funding than is currently available. Manufacturing and treating of products from plantation fores...

Efficiency of the Amazon Forest Oils as Preservatives to the Attack of cellulolytic fungi in Pine Wood
2012 - IRG/WP 12-30599
The bobbins of wood are used for storage and field installation of cables from the electricity and telecommunications sectors. There are legal requirements governing the Brazilian ways of treating the wood used in these sectors, aimed at preventing pollution and protecting nature. When exposed to severe environmental conditions in Brazil these products are degraded and occurs many operational prob...

Vacuum drying of European oakwood: Color, chemistry and anti-oxidant potency of wood. Improving appearance in forest value added products
2008 - IRG/WP 08-40432
In hardwoods used for decorative and appearance purposes, wood colour is one of the most important factors of wood quality; in addition colour is related with durability and biological decay of wood. Wood discolouration during drying is mainly affected by heat, light, physiological reactions, combinations of reactions, biochemical and chemical reactions, and micro-organisms attack. In freshly fell...

Sustainable Mycological Alternatives in Natural forest and Conifer plantations in México
2012 - IRG/WP 12-10792
Concepts of mycoforests, mycosylviculture and their relationship to education, production and sustainable management of fungi in forests in México are analyzed. These concepts may be applied in Mexican protected areas, parks and forestry rural communities and improve socio-economic conditions. Two decades ago commerce of wild edible mushroom in the world was relatively small; mushroom industries ...

Natural durability of plantation-grown coast redwood (Sequoia sempervirens) in New Zealand
2014 - IRG/WP 14-10817
There is wide variation in the wood properties of plantation-grown coast redwood in New Zealand. Contributing factors are the seed source, silviculture, growth and age of the trees in the plantation forests. Little is known about how these factors affect the variation of wood properties among and within the trees of New Zealand’s coast redwood forests. Heartwood of plantation-grown coast redwood...

Molecular characterization and biodiversity of wood-decaying fungi in French Guiana
2014 - IRG/WP 14-10825
Fungi from tropical regions are currently under-represented in the classification system. Indeed, difficult access to tropical forests and irregular occurrence carpophores make it complicated to study fungus species in such environments, unlike in European zones where fungal diversity and taxonomy are better known. The purpose of this work was to enhance classification by integrating new data that...

Enhancing knowledge transfer in the wood protection sector
2018 - IRG/WP 18-50338
In order to meet the needs for the developing bio-based economy, maintaining and expanding the market potential for wood raw materials and wood products in indoor and outdoor construction uses remains a key activity for industries in the biotechnological and forestry sector respectively. A major restraint in this respect is the drastically deviating views and expectations on quality and performanc...

Pest and pathogens threaten the sustainability of plantation forestry: Global research collaboration will define the future
2018 - IRG/WP 18-50341
Global plantation forestry is dominated by intensively managed stands of Pinus, Populus, Acacia and Eucalyptus species. The greater proportion of these plantations has been established in areas where the trees are non-native and have thus been separated from their natural enemies. In all documented cases, these plantations have initially been free of serious pest and disease problems. But as ti...

The Commercial Forestry and Forest Products Industry in South Africa – A brief overview
2018 - IRG/WP 18-50342
The presentation made by Mr Michael Peter, Executive Director of Forestry South Africa, provides insight into the commercial forestry and forest products industries in South Africa. The forestry industry in South Africa is based solely on the propagation of exotic trees, grown in plantations in the higher rainfall regions of South Africa.
The presentation shows the ownership, geographical extent...

Green Coloration of Wood in the Forest and Laboratory by Chlorociboria spp. – Applications for Furniture
2019 - IRG/WP 19-10947
Discoloration of wood caused by living saprophytic fungi is commonly found on lumber. These fungi do not destroy the integrity of wood, but the discolorations they cause are often considered undesirable. In Tunbrigde Wells (Great Britain), seldomly found green colored wood, usually considered commercially irrelevant, was valued for use in restoration of wood inlay artwork.
The aim of this researc...

Enhancing the durability of low durability Eucalyptus plantation species: a review of strategies
2020 - IRG/WP 20-40910
Eucalyptus species native to Australia have shown excellent growth rates, good physical properties and resistance to diseases. As a result, they are widely planted globally for a variety of uses. One negative aspect of many of these faster growing species is that they have a high percentage of low durability heartwood that resists preservative treatment. In Australia, large plantations of these sp...
