Variation of Chemical Components in Sapwood, Transition Zone, and Heartwood of Dalbergia odorifera and Its Relationship with Heartwood Formation [PDF]
Heartwood has a high economic value because of its natural durability, beautiful color, special aroma, and richness in active ingredients used in traditional Chinese medicine. However, the mechanism of heartwood formation remains unclear. Dalbergia odorifera was selected as the object of research to analyze this variation in the chemical composition of

Combined analysis of the metabolome and transcriptome reveals the mechanism of Red heart Chinese fir heartwood formation [PDF]
Cunninghamia lanceolata, a coniferous timber species solely endemic to China, possesses a natural variant known as Red-heart Chinese fir. This variant is renowned for the distinctive color of its heartwood, where the chestnut-brown xylem significantly ...

Heartwood Formation in Pinus radiata (D. Don) [PDF]
IN a paper which is to be published by the New Zealand Forest Service entitled “Heartwood Formation in Pinus radiata”, it has been shown that conditions which are conducive to the occurrence of physiological drought retard heartwood formation in this species, but that where a deep root system can be developed in an area with adequate rainfall but ...

Effects of pruning on heartwood formation in Scots pine trees [PDF]
The object of this study was to investigate the effect of pruning on heartwood formation in mature Scots pine (Pinus sylvestris L.) trees. Fifty trees were treated by three different intensive pruning regimes: 42, 60 and 70 percentage of defoliation ...

Heritability of Heartwood Formation in Pinus radiata D. Don [PDF]
AN important change which occurs in the wood of most trees as they grow older is the transformation of sapwood into heartwood. This change is associated with the death of the ray and vertical parenchyma cells, and definite modifications to the anatomy of both softwoods and hardwoods1.

Positional differences in the micro- and ultra-structural variations of ray parenchyma cells during the transformation from sapwood to heartwood [PDF]
Ray parenchyma cells are involved in the initiation of heartwood formation. The position within a ray influences the timing of ray parenchyma cell differentiation and function; however, there is little information concerning the positional influence on ...

Can bark stripping cause red heartwood formation in beech stems? [PDF]
Injuries to standing trees caused by logging and the subsequent changes in biochemical composition and anatomy of affected tissues lead to wood quality loss, thus lowering the commercial value of roundwood. In this study, we investigated the influence of

Predicting red heartwood formation in beech trees (Fagus sylvatica L.)
Abstract Beech forests (Fagus sylvatica L.) represent the natural vegetation cover for the majority of sites in Germany. Although coniferous forests actually dominate, beech is the most important among the deciduous-tree-species in Germany, when considering the area and the economics.

Forest health, heart rot disease, and their impact on the source of carbon-based greenhouse gas fluxes. [PDF]
Summary Forest health is critical for sustaining ecosystem services like carbon sequestration. Heart rot, a widespread disease in upland northern hardwood forests, may affect greenhouse gas (CO2 and CH4) fluxes, but its impacts remain poorly measured. Using non‐destructive tomography and direct gas flux measurements, we quantified the effects of heart ...
