인도네시아산 White Jabon과 Red Jabon의 해부학적 특성 비교

Abstract

Anatomical characteristics of White Jabon (Arthocephalus cadamba) and Red Jabon (Arthocephalus macrophyllus) were investigated by IAWA hardwood feature list. Both species were diffuse-porous, and radial multiple pore with 2~3 rows was mostly observed. Tangential diameter of vessel lumina was 100 to , and vessels per millimeter were 5 to 20. White Jabon has more vessels than Red Jabon. The number of solitary pore per millimeter in both species was similar, but more pore multiple was observed in White Jabon. Axial parenchyma diffuse was observed in both species, but axial parenchyma of White Jabon was hardly identified on the cross section. Rays were classified into body ray procumbent with over 4 rows of upright/square marginal cells type and partly all ray upright and/or square type on radial section. Ray width 1 to 3 and 1 to 2 observed in White Jabon and Red Jabon, respectively. Ray height of White Jabon was and Red Jabon . Fiber length was the range of 900 to in both species, and it showed a tendency to increase from pith to bark. Consequently, it is considered that pore multiple, ray width and axial parenchyma are to be suggested the keys for identification of both species.
