“…Gelatinous fibers are usually larger than non-gelatinous fibers (ZOBEL; VAN BUIJTENEN, 1989). Some studies indicate that the increase in length of gelatinous fibers is influenced by the formation of tension wood (JOUREZ;RIBEAUX;LECLERQ, 2001;PANDE, 2013). Eccentric growth of the trunk can be a result from increased duration of cell division or division rate in the vascular cambium, and this can cause the fiber length in the tension region to be higher or shorter than normal wood.…”

Tension wood is an important anatomical structure for its participation in the orientation of the trunk and the architecture of the branches as a function of structural reinforcement. However, its presence in large amounts significantly affects the technological properties of wood, just as in the rubber tree. Nevertheless, there is still demand for information about the origin, distribution and structural features in this species. Thus, this study aims to characterize the cellular structures in tension and opposite wood in Hevea brasiliensis (rubber tree), as well as its radial and longitudinal distribution. Discs at the base and the middle of the commercial logs were collected from three trees in a commercial plantation located in Tabapoã - SP. Tangential diameter of vessels, fiber length (gelatinous and non-gelatinous fibers), microfibril angle and proportionality of cellular elements (vessels, axial parenchyma, ray, gelatinous fibers and non-gelatinous fibers) were measured, and influence of gelatinous fiber presence in vessel diameter was observed. Gelatinous fibers were observed in the two types of wood and in the two trunk heights. Both types of wood were distinguished by gelatinous fiber length and the proportion of axial parenchyma. The tension wood in mid-trunk was the most different, with long gelatinous fibers and less abundant, larger vessel diameter and vessel proportion. Moreover, smaller vessel diameter was observed in the regions with a high proportion of gelatinous fibers, suggesting that the plant invests more support than in liquid transport.

“…Many studies reported that dbh was the most commonly used and the most effective variable for estimating heartwood volume in many tree species (Yang et al 2020). Regression equations, relating age to the amount of heartwood, have been developed for various species, e.g., Indian rosewood (Pande 2013) and Teak (Moya et al 2020).…”

“…Heartwood formation is a natural growth-regulating process related to the development of a tree and helps to maintain an optimum sapwood volume (Pande 2013). Heartwood and sapwood have different properties with their proportion within a stem having a significant effect on the rational utilization of timber.…”

Abstract. Meunpong P, Penboon C, Kuasakun N, Wachrinrat C. 2021. Tree dimension and environmental correlates of heartwood content in Siamese rosewood (Dalbergia cochinchinensis). Biodiversitas 22: 3297-3303. Siamese rosewood (Dalbergia cochinchinensis) is considered amongst the prime timber varieties in high demand with the wood fetching high prices in the international timber market. Therefore, illegal logging and smuggling of Siamese rosewood from natural forests poses a severe problem in Thailand. Heartwood and its content is the most valuable part of Siamese rosewood, which in practice, cannot be measured directly in living trees. Hence, we investigated the relationship between the heartwood content of Siamese rosewood, and tree dimension and environmental characteristics across eleven plantations throughout Thailand construct a model for predicting the heartwood content using specific environmental variables. The results indicate that there were differences in the mean annual increment of all measurement parameters (d0, d30, dbh, and total height of a tree) across eleven plantations studied. However, we did not find any statistically significant differences between the increments in heartwood diameter. Furthermore, we found that suitable location for Siamese rosewood plantation could result in doubling of growth rate. We report that dbh was the most relevant variable and could be used as a predictor for heartwood content. In terms of environmental variables, soil properties at top layer that affect the heartwood content were particle density, organic matter, and silt particles. Using the resulted equation formulated in this study may be useful when planning areas for suitable plantations of Siamese rosewood in Thailand.

“…It is could be that the percentage of heartwood increases with increasing tree growth (diameter and height). Pande (2013) reported that there was a very strong positive correlation (0.1% significance level) between tree diameter (DBH) and heartwood area and a strong positive correlation (1% significance level) between tree height and heartwood area on Dalbergia sissoo. However, the results of one-way ANOVA (Table 2) show that heartwood percentage is not significantly different between three generations of A. mangium.…”

Breeding activities of Acacia mangium have been established to the second breeding generation (F2) in Wonogiri, Central Java, Indonesia, in order to increase stand productivity and the quality of timber products. However, research on wood properties of A. mangium in breeding program is still limited in Indonesia. This study aims to determine the properties of wood, especially the physical and mechanical properties of three breeding generations (F0, F1, and F2) of A. mangium wood. Furthermore, relationship between air-dried density and mechanical properties was also clarified. As a result, the physical and mechanical properties of wood are not significantly different among three generations, indicating that this breeding activity did not affect a significant decrease in the physical and mechanical properties of A. mangium wood. In addition, air-dried density has significant correlation with all mechanical properties measured.
