Chemical aspects of heartwood formation

Wood Science and Technology, 1968
A complete understanding of the processes underlying the transformation of sapwood into heartwood requires consideration of the chemical as well as other aspects of the change. A review of recent investigations into chemical topics is presented. There is a decrease in the storage materials from the outer and middle sapwood to the heartwood boundary ...

Douglas-fir polyphenols and heartwood formation

Phytochemistry, 1997
Abstract Phenolic extractives have been isolated from Douglas-fir sapwood and heartwood and identified by NMR and mass spectroscopy. Pinocembrin, [5,5′]-bisdihydroquercetin and two lignans, pinoresinol and 2,3-dihydro-2-(4′- O -β-glucopyranosyl-3′-methoxyphenyl)-3-hydroxymethyl-5-(3-hydroxypropyl)-7-methoxy-benzofuran are reported for the first time ...

New Insights into Heartwood and Heartwood Formation

2013
The formation of true or obligate heartwood in the innermost living xylem tissues of many tree species is one of the most important ecological and economical secondary differentiation processes. Natural durability, biological, technological, and esthetic parameters of wood and its products depend on the presence, quality, and quantity of heartwood ...

Formation Mechanism of Heartwood and Research Status

2021
The formation mechanism of heartwood is a scientific problem which has not been fully revealed in wood science. Effective regulation of heartwood formation is a scientific problem that is rarely studied and has not yet achieved a breakthrough in the field of forest cultivation.

Heartwood, its function and formation

Wood Science and Technology, 1976
Some of the changes which occur in wood during the transition from sapwood to heartwood have been reviewed. The nature of these changes suggest that heartwood formation is a regulatory process serving to keep the amount of sapwood at an optimum level.

CARBON DIOXIDE AND THE FORMATION OF HEARTWOOD

New Phytologist, 1971
SummaryThe state of knowledge of the transition of sapwood into heartwood in trees is reviewed, and attention is drawn to the composition of the gas mixture available to such cells as remain alive in wood. The probable effect of such a mixture is postulated and experiments indicate that the high concentrations of carbon dioxide known to exist inside ...
