Mechanical Property of 9 Years Old Thinning of Teak Plantation in Thailand

Abstract

Abstract. Based on the study of the conditions and problems of thinned teak in Thailand it's with findings that thinned teak or so called thinning for distance clearance being with small stems and can be sold at low price. thinned teak was with mechanical property different with teak from natural forest with age over 30 years old with the results of most of the tests were with findings that the values of the mechanical property of teak from natural forest with age over 30 years were more valuable than the values of the mechanical properties of thinned teak with exception on Standard Test Method for Tensile and Cleavage Test of Timber which thinned teak was with more value than teak from natural forest with age over 30 years old. For guidelines on market value added for thinned teak can be made by producing to use in the context of the design of household goods made of wood as the guide for resolution of problems and creation of artistic work pieces household goods made of wood.

Analysis of Chemical Composition of Extractives by Acetone and the Chromatic Aberration of Teak (Tectona Grandis L.F.) from China

“…However, poor visual appearance in green teak is common by reason of the uneven and unstable surface color [3]. To provide basic information for the wood industry, the physical and mechanical properties and compositions of teak have been analyzed by many researchers [4,5,6,7]. A lot of research has been done into the breeding, plantations and growth of teak so as to develop high productivity and quality varieties [8].…”

Productivity of Clonal Teak Plantation Under Different Spacing and Thinning Intensity in Java Monsoon Forest

“…It indicates that the diameter increment in the no-thinning treatment decreases with the increasing age of the teak clones. Silvicultural thinning is a way to stimulate plant conditions to increase growth (Djati et al, 2014) (Seviset et al, 2017). Long-term thinning affects tree growth positively (Stefančík et al, 2018).…”

“…In this respect, thinning plays an essential role in optimizing teak growth. In a given period with the same spacing, teak growth will decline or not increase, thus requiring thinning to optimize teak growth (Seviset et al,2017).…”

“…However, high thinning intensity can increase both branch diameter and the number of knots (Isaac-Renton et al, 2020). Straight stems and low branching are crucial factors(Seviset et al, 2017). For this reason, increasing the DBH of the plant can be done by increasing the maintenance of the plant in the form of pruning.…”
