Anatomical properties of Elm (Ulmus wallichiana) wood in correlation with technological and wood working properties
Khalid Hussain and G. M. Nasir
ABSTRACT
Elm (Ulmus wallichiana) wood was studied for its anatomy to ease identification of the species, evaluate various technological properties and find out its better utilization. Permanent slides of cross, radial and tangential sections of the wood were prepared by standard laboratory procedures and observed under the microscope. Data were collected for the frequency and dimensional measurements of different wood elements/structures. Results revealed that in Elm wood, the fibers were longer, medium in diameter, wide lumened and fairly thick-walled due to that the wood may be relatively better in strength. The vessels were lower in frequency but quite larger in diameter and the wood can be seasoned without any difficulty. The wood rays were medium per unit area and in size. The axial parenchyma was abundant, occupied approximately one third volume of the wood for the reason; the wood may be non-durable and require preservative treatment before used as solid wood. The wood may be less durable however it can be easily preserved with chemicals. Further, due to better fiber morphological characteristics, the wood can be used for pulp and paper manufacture.
