The colonization of selected naturally durable timbers by marine fungi and borers
1977 - IRG/WP 439
In recent years, concrete and metal have been widely substituted for wood in contact with sea water, but wood products have not lost their usefulness under such conditions. In many cases, wood if sound and durable, may prove to be the most practical and economical of materials used in sea water exposure. Timber when immersed in the sea may be attacked by micro-organisms (bacteria and fungi) and ma...

Wood Natural durability study source of biomolecules: case of Dicorynia guianensis Amsh. heartwood
2016 - IRG/WP 16-10871
The chemical investigations of Dicorynia Guianensis heartwood led to the isolation of four new indole alkaloids for the first time in this plant Compound (1) identified as spiroindolone 2’,3’,4’,9’ -tetrahydrospiro [indoline-3,1’pyrido[ 3,4-b]-indol ]- 2- one, and compound (3) described as nitrone 1-methyl-4,9 -dihydro-3H-pyrido [3, 4-b] indole 2 – oxide and were isolated for the first...

Comparison of 1H qNMR and NIR spectroscopic methods to predict heartwood decay resistance in Dicorynia guianensis Amsh
2017 - IRG/WP 17-20601
Dicorynia guianensis is by far the most exploited wood in French Guiana, as it is an abundant tree species associated with good technological properties. However, the decay resistance of D. guianensis wood against lignivorous fungi pathogens is sometimes variable. Therefore, the development of tools to predict the decay resistance of D. guianensis heartwood is relevant in wood science and agrofore...

Field tests of different tropical wood species in sea water
2022 - IRG/WP 22-30773
A number of tropical timbers have been tested according to EN 275 at Kristineberg Marine Research Station in Sweden since 1999. Most of these tests have started during the last 5-8 years. Wood species included have been Lophira alata (Azobé/Ekki), Minquartia guianensis (Manwood/Acaria), Chlorocardium rodiei (Greenheart), Cyclodiscus gabonensis (Okan/Denya), Shorea spp. (Bankirai), Dicorynia guia...
