Obtaining salts of resin acids from cuban pine by metathesis reactions
(2020-06-15)
The resin acids obtained from the Cuban pine rosin are the starting material for the development and application of metathesis reactions. These reactions allow the obtaining of salts with high added value which could be ...
Resin-adhesive formulations for bonding exterior-type plywood using chilean radiata pine and four hardwoods
Phenol-formaldehyde resole resins were formulated similarly to plywood resins used in the United States. Some laboratory resins were repeated in a pilot-plant reactor. Specification characteristics were determined on each ...
Genetic variation of wood and resin production in Pinus caribaea var. hondurensis Barret & Golfari
(Johann Heinrich Von Thunen Inst-vti, 2016-12-01)
The purpose of this work was to estimate genetic parameters and selection gain of Pinus caribaea var. hondurensis progeny trial for wood and resin production as well as correlation between them. Experiment was established ...
Increment Coring Induced Traumatic Resin Ducts in White Spruce But Not in Lodgepole Pine
(Tree-Ring Society, 2020-01)
Injury from sampling increment cores may induce defense responses in trees, which may vary between species and reflect differing defense allocation strategies against attack by insects and pathogens. We recorded presence ...
Pattern Recognition in Thermal Images of Plants Pine Using Artificial Neural Networks
(Springer, 2013-01-01)
Pine is used primarily as a source of raw materials for the industries of lumber and laminated plates, resin, pulp and paper. Pine may be affected, from the nursery to adults, in plantations by pathogens such as fungi ...
