Heartwood Formation in Pinus radiata (D. Don) [PDF]
Nature, 1953 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 ...

Identifying heartwood-rich stands or stems of Pinus sylvestris by using inventory data
Silva Fennica, 1999 Variations in heartwood percentage, heartwood radius and sapwood width, within and between stands of Scots pine (Pinus sylvestris L.), were analysed using a database of 198 CT-scanned (computer tomography) stems from 33 research plots (stands ...

Developmental Changes in Scots Pine Transcriptome during Heartwood Formation [PDF]
Plant Physiology, 2016 Scots pine (Pinus sylvestris L.) wood is desired in woodworking industries due to its favorable timber characteristics and natural durability that is contributed by heartwood extractives. It has been discussed whether the Scots pine heartwood extractives (mainly stilbenes and resin acids) are synthesized in the cells of the transition zone between ...

Involvement of peroxidases in the formation of the brown coloration of heartwood in Juglans nigra [PDF]
Journal of Experimental Botany, 2002 Oxidase activities were investigated within the cross-section of walnut trunk in relation to the brown staining of heartwood, especially in the transition zone where the colour change occurs. The distribution of peroxidase activity was investigated using 3,3'-diaminobenzidine (DAB) or guaiacol as a substrate.

Spatiotemporal Variation and Covariation of Heartwood Color in Planted Teak Wood from Ghana
BioResources, 2022 Heartwood color is a complex trait that affects the economic and aesthetic value of the wood but is highly variable. How the color of the heartwood varies spatially and temporally is poorly understood.

Radial Distribution of Lipophilic Extractives in Walikukun (Schoutenia ovata Korth.) Wood
South-East European ForestryWalikukun (Schoutenia ovata Korth.) is a commercially significant wood species in Indonesia. Heartwood, in particular, is important due to the natural durability and aesthetics, while lipophilic extractives play a crucial role in the formation. Therefore,
