Abstract
The Elm species Fraxinus ornus L. was selected to study the effect of
some topographical factors on the anatomical characteristics of its
wood. Three trees of this species were selected from each site. Three
areas were chosen in the Rewandiz District of Erbil Governorate,
northern Iraq. The area is 123 km from Erbil. Their elevations range
between 685 and 1180 meters above sea level latitude, longitude, and
Aspects ratios. Slope and the sites from which the samples were taken
were recorded. The results of this study showed a significant
environmental influence and variation among the studied trees on the
anatomical characteristics of the wood. A variation was found in the
average dimensions of the vessel elements in the three studied sites.
Environmental effects were also found on the dimensions of the fibers,
according to the facades, elevations, and slope. One of the most
important diagnostic results for the wood of this species is the recording
of the presence of separated fibers in this study. It was also found that
the qualitative characteristics are of great diagnostic importance, as the
number of rows of interlaced holes in the samples ranged from one row
(Uniseriate) to two rows (Biseriate), while the perforated plate was of
the simple perforation plate type the presence of thickenings, Spiral. The
study was reinforced with illustrative images of the separated cells.
Illustrative images of the separated fibers enhanced the study.
