Radial variation of wood properties of Sengon (Paraserianthes falcataria) and Jabon (Anthocephalus cadamba)

摘要

Anatomical parameters and density were measured for each segmented ring to investigate the juvenile and mature pattern of radial variation for each property of 7 years old Sengon (Paraserienthes falcataria) and Jabon (Anthocephalus cadamba). Observed patterns were described using three different models: (I) linearly increase or decrease, (II) exponential, (III) linearly equal to intercept. The pattern of radial variation showed in both of species, all properties in vessel elements (vessel frequency and mean vessel area), fiber length and density in Jabon had model II. Lumen diameter, cell wall thickness and density in Jabon had model I and also for fiber diameter of bottom part in both of species, diameter lumen of upper part Sengon and cell wall thickness of bottom part Sengon. Model III had found in fiber diameter of upper part in both species and lumen diameter of bottom part Sengon.
