Predictions of Mature and Total Tree Wood Properties from Juvenile Wood
1998Rarely can accurate predictions of mature wood properties be made from the wood of juvenile trees, but it is very important to learn how to do so as accurately and as soon as possible. It was clearly stated by Loo et al. (1984): “Genetic gains per unit time are inversely proportional to the length of a selection cycle, thus the value of the juvenile ...

Juvenile Wood of Hardwoods Judged by Density Variation
IAWA Journal, 1984In the ring-porous hardwoods the changes of basic density are influenced by ring width, while basic density of diffuse-porous hardwoods is almost independent of ring width. The radial variations of basic density in each ring width class are useful for distinguishing between age and growth effects.

Demarcation of juvenile and mature woods of planted Chinese fir and its wood quality prediction
Journal of Forestry Research, 1998According to the data of trashed length, micro fiber angle, air density, ring width and late wood percentage, with the analysis of optimum method of classification, the boundary line of juvenile wood and mature wood of planted Chinese fir (Cunninghamia lanceolata) was determined as the 14th year.

Juvenile Wood and Its Properties
2009Wood based products (especially building sector) are desired homogeneous as much as possible. Juvenile woodwhich occurs at first years of trees growth (approximately 5-20 years) may impair this homogeneous. Becausejuvenile wood show too different in mature wood, which comprise of after juvenile wood (more than 20 years)and have higher strength ...

Effect of juvenile wood on wood properties variations in Eucalypts
2001The heterogeneousness of the physical and mechanical properties of Eucalypts from plantations limits the utilization of this group of species for solid wood products. In effect, wood products manufacturers aim to process a material as homogeneous as possible in order to be able to propose standard quality products to their customers.

Some Physical and Mechanical Properties of Juvenile Wood and Mature Wood of Taurus Cedar
2012Bu çalışmada, Kahramanmaraş-Başkonuş mevkiinden temin edilen Toros sedirinin (Cedrus Libani A.Richard) genç odun ve olgun odununun bazı fiziksel ve mekanik özellikleri Türk standartlarına göre belirlenmiştir. Genç odunun hava kurusu yoğunluk, tam kuru yoğunluk, hacmen daralma, hacmen genişleme, lif doygunluk noktası ve taze hal rutubeti sırasıyla; 574 ...

A Study on Differences in Fiber Morphology between Juvenile Wood and Mature Wood
2017Bu çalışmada, genç odun ve olgun odun arasında lif morfolojisindeki farklılıklar sedir ve okaliptüs ağaçlarından elde edilen test örnekleri üzerinde araştırılmıştır. Bu amaç için, lif uzunluğu, lif genişliği, lümen çapı ve çeper kalınlığı ölçülmüştür. Ölçümler genç odun ve olgun odun örnekleri üzerinde ayrı ayrı yapılmıştır.
