TREE RING CHARACTERISTICS of 30-YEAR-OLD SWIETENIA MACROPHYLLA PLANTATION TREES Cheng-Jung Lin* Chih-Hsin Chung Chih-Lung Cho Te
TREE RING CHARACTERISTICS OF 30-YEAR-OLD SWIETENIA MACROPHYLLA PLANTATION TREES Cheng-Jung Lin* Associate Researcher Department of Forest Utilization Taiwan Forestry Research Institute Taipei, Taiwan E-mail: [email protected] Chih-Hsin Chung Assistant Researcher Department of Forest Management Taiwan Forestry Research Institute Taipei, Taiwan E-mail: [email protected] Chih-Lung Cho Professor Department of Natural Resources National I-Lan University Ilan, Taiwan E-mail: [email protected] Te-Hsin Yang Assistant Professor Department of Forestry College of Nature Resource and Agriculture National Chung Hsing University Taichung, Taiwan E-mail: [email protected] (Received October 2011) Abstract. Ring characteristics of mahogany (Swietenia macrophylla K.) plantation trees grown in Taiwan were explored. Significant differences in average ring width (RW) and ring density (RD) occurred among three tree-diameter classes and three radial stages of ring numbers. RW in the radial direction decreased from the pith outward to the bark and followed a distinctive three-stage variation pattern (juvenile, transition, and mature zones). RD in the radial direction increased slowly from the pith outward to the bark. Wider tree rings and lower density are associated with juvenile wood close to the pith, whereas narrower tree rings and higher density are typical for mature wood outward toward the bark. RD in overtopped trees was higher than that in dominant trees. However, RW in dominant trees was wider than that in intermediate and overtopped trees. Earlywood density, latewood density, maximum density, and minimum density were the most important factors determining overall RD. There was a weak relationship between RW and RD, indicating that it is unlikely for growth rates of mahogany plantation trees to have a significant impact on wood density. -
Population Genetic Structure of Mahogany (Swietenia Macrophylla

B, Asa Norte, 70790-160, Brasilia-DF, Brazil Abstract Mahogany (Swietenia macrophylla, Meliaceae) is the most valuable and intensively exploited Neotropical tree. No information is available regarding the genetic structure of mahogany in South America, yet the region harbours most of the unlogged populations of this prized hardwood. Here we report on the genetic diversity within and the differentiation among seven natural populations separated by up to 2100 km along the southern arc of the Brazilian Amazon basin. We analysed the variation at eight microsatellite loci for 194 adult individuals. All loci were highly variable, with the number of alleles per locus ranging from 13 to 27 (mean = 18.4). High levels of genetic diversity were found for all populations at the eight loci (mean ffE = 0.781, range 0.754-0.812). We found moderate but statistically significant genetic differentiation among populations considering both estimators of FST and RST, 9 = 0.097 and p = 0.147, respectively. -

Chemometric Differentiation of Dipterocarpaceae Wood Species Based on Colorimetric Measurements

A simple and reliable means for the differentiation of wood species could contribute to the control of this fraud. In this study, eight (8) commercially important and endangered dipterocarp timber wood species and mahogany were differentiated through colorimetric measurements carried out on hot water and ethanol extracts from the samples. Colorimetric measurements were done using a fabricated colorimeter that measured the absorption of blue, green, and red radiation. Chemometric analysis of the colorimetric data using principal component analysis (PCA) and hierarchical cluster analysis (HCA) revealed clustering, which enabled an efficient differentiation of the wood species.

Sam- ples representing different ramin species, confamilial genera and morphologically similar taxa were obtained. DNA extraction from leaf material and wood products was achieved using com- mercially available kits. Five chloroplast genes were examined for Single Nucleotide Polymor- phism (SNP) loci capable of discriminating ramin. A locus within the matK gene was selected and a TaqMan® assay designed for sample genotyping. The assay was validated against different spe- cies to demonstrate its specificity and reproducibility. The final assay provides a robust, cost-effec- tive, transferable method for identifying processed ramin. The research represents a feasibility study, addressing each of the steps required to develop a genetic identification assay for enforce- ment use; however, it should be noted that further work is required to produce a fully validated forensic identification tool. -

This has led to many of the tropical forests viable alternative in many of WWF’s priority places. being plundered for these highly prized species. Even in forests where there are good levels of forest management, there is a risk of a shift in species composition Markets are hard to change, as buyers from consumer countries often aren’t in natural forest stands. This over-exploitation can also dissuade many forest willing to switch from purchasing the traditional species which they know do managers from obtaining Forest Stewardship Council (FSC) certification for the job for the products that they are used in, and for which there is already their concessions, as many of these high value species are rarely available in a healthy market. To enable the market for LKTS, there is an urgent need to sufficient quantity to cover all of the associated costs of certification. -
