“…It is known that significant positive correlation was found between wood density and compressive strength (Kollmann & Côté 1984). This tendency is also true for tropical-fast-growing tree species (Chowdhury et al 2009, Ishiguri et al 2012a, Pertiwi et al 2018. The obtained results in the present study were similar to these reports, suggesting that mechanical properties of this species can be predicted by basic density.…”

“…On the other hand, fibre wall thickness was also significantly correlated with fibre diameter (r = -0.866) or basic density (r = 0.592). Pertiwi et al (2018) reported that a significant correlation (r = 0.47) was found between fibre wall thickness and basic density in Neolamarckia cadamba trees planted in Indonesia. Similar results were also obtained in Eucalyptus tereticornis and Falcataria moluccana (syn.…”

Radial variations of anatomical characteristics and wood properties were investigated for a relatively slowgrowing tropical tree species, Peronema canescens. Based on the results, effects of radial growth rate on anatomical characteristics and wood properties were evaluated. The mean values of stress-wave velocity of stem, vessel diameter, cell wall thickness of wood fibre, wood fibre length, vessel element length, basic density and compressive strength parallel to grain at green condition were 3.94 km s -1 , 201 µm, 2.05 µm, 1.05 mm, 0.21 mm, 0.48 g cm -3 and 36.9 MPa, respectively. No significant correlations were found between growth characteristics (stem diameter at 1.3 m above ground and tree height) and anatomical characteristics or wood properties. These results suggested that anatomical characteristics and wood properties of this species were independent from growth characteristics, even in relatively slow-growing tree species in the tropics.

“…It is characterized by a rounded crown, straight trunk, and rapid growth. Its timber has the properties of straight texture, easy planning, fast drying, and hardness [ 3 , 4 ]. It is widely used for multiple industrial and commercial purposes, such as wood board, pulp, and paper making [ 5 , 6 ].…”

“…A progeny test was also reported in India [ 18 ] to estimate the genetic parameters of phenotypic traits and to select better individuals for genetic improvement. Modern biotechniques were applied to developing plant propagation and identifying functional genes, including tissue culture and propagation [ 19 , 20 ], transcriptome analysis of gene expression [ 21 , 22 ], expression sequence tags (ESTs) in xylem tissue [ 23 ], gene discovery of developing xylem tissue [ 4 ], the evolution of gene families [ 24 ], and polyploidization breeding [ 25 ]. A previous study used ISSR (inter-simple sequence repeat) dominant markers to analyze the genetic differentiation between two artificial populations and among six natural populations in Malaysia [ 26 ].…”

Neolamarckia cadamba (Roxb.) Bosser is a fast-growing deciduous tree species and belongs to the Neolamarckia genus of the Rubiaceae family. This species has great economic and medical values in addition to being an important timber species for multiple industrial purposes. However, few studies have examined the genetic diversity and population structure in the natural distribution of this species in China. Here, we applied both the haploid nrDNA ITS (619 bp for aligned sequences) and mtDNA (2 polymorphic loci) markers to investigate 10 natural populations (239 individuals in total) that covered most of the distribution of the species in China. The results showed that the nucleotide diversity was π = 0.1185 ± 0.0242 for the nrDNA ITS markers and π = 0.00038 ± 0.00052 for the mtDNA markers. The haplotype diversity for the mtDNA markers was h = 0.1952 ± 0.2532. The population genetic differentiation was small (Fstn = 0.0294) for the nrDNA ITS markers but large (Fstm = 0.6765) for the mtDNA markers. There were no significant effects of isolation by distance (IBD), by elevation, and by two climatic factors (annual average precipitation and tem perature). A geographic structure among populations (Nst<Gst) was absent. Phylogenetic analysis showed a highly genetic mixture among individuals of the ten populations. Pollen flow was substantially greater than seed flow (mp/ms ≫ 1.0) and played a dominant role in shaping population genetic structure. The nrDNA ITS sequences were neutral and all local populations did not undergo demographic expansion. The overall results provide fundamental information for the genetic conservation and breeding of this miraculous tree.

“…On the other hand, in broad-leaved tree species growing in the tropics and sub-tropics, anatomical characteristics, and physical and mechanical properties of secondary xylem stabilize in relation to 1) distance from the pith or 2) cambial age (Wiemann and Williamson 1988;Honjo et al 2005;Kojima et al 2009c;Lachenbruch et al 2011). The maturation depending on diameter growth has been found in many fast-growing tree species, such as Acacia spp., Azadirachta excelsa, Casuarina equisetifolia, Gmelina arborea, Neolamarckia cadamba, Ochroma pyramidale, and Falcataria falcata (Wiemann and Williamson 1988;Honjo et al 2005;Chowdhury et al 2009;Kojima et al 2009a, b, c;Wahyudi et al 2014Wahyudi et al , 2016Ishiguri et al 2016;Hidayati et al 2017;Pertiwi et al 2018Pertiwi et al , 2022.

The knowledge of xylem maturation manner is importance to foresters and wood processors as it has major implications for end-product quality. This study aims to evaluate the maturation manner of secondary xylem in Eucalyptus camaldulensis for solid wood production. The samples were 45 twelve-year-old trees from 15 families with different radial growth in a progeny test site for the E. camaldulensis second generation in Thailand. Two mixed-effect models (cambial-age dependency and diameter-growth dependency models) were developed for radial variation of wood properties, resulting in that the cambial-age dependency model was a good fitting for all wood properties rather than growth-diameter models, with a few exceptions. Therefore, the secondary xylem of this species matures depending on cambial age rather than diameter growth. Changing ratios of multiple wood properties at 1-year intervals estimated by the cambial-age dependency model became stable after a cambial age of 11.8 years. The wood formed after starting xylem maturation showed 1) longer wood fiber length, 2) smaller number and larger diameter of vessels, 3) larger diameter and thicker wall thickness of wood fiber, and 4) higher density and compressive strength, rather than those formed in the early growth stage. Based on the results, desirable wood properties for solid wood products can be obtained by prolonging the rotation period from the present short rotation periods.
