Database for radial variations of anatomical characteristics and wood properties in tropical trees (DaRV-tropics)

Abstract

‘Database for radial variations of anatomical characteristics and wood properties in tropical trees (DaRV-tropics)’ is constructed using data collected by the Laboratory of Forest Products and Wood Material Science, School of Agriculture, Utsunomiya University, Japan, to promote effective utilization of forest resources. The concept to construct this database is ‘how we can construct a database easier’ and ‘how we can maintain it easier’. The first edition of DaRV-tropics includes 39 study project data consisted of 298 individual trees from 35 species (24 genera from 14 families) collected from Indonesia, Malaysia, and Thailand. DaRV-tropics includes radial variations of measured traits, such as basic density, compressive strength parallel to grain, length and diameter of wood fiber and vessel element, vessel frequency, and wall thickness of wood fiber, as well as mean values. Our database has made it possible to provide basic information that contributes to the development of research on tropical hardwoods.
