TY - JOUR T1 - Anatomical Investigation of the Leaves of Two Morphologically Similar Species, Platanus orientalis (Platanaceae) and Liquidambar orientalis (Altingiaceae) AU - Ahmet Sargin, Seyid JO - Botany Research Journal VL - 14 IS - 1 SP - 10 EP - 17 PY - 2021 DA - 2001/08/19 SN - 1995-4751 DO - brj.2021.10.17 UR - https://makhillpublications.co/view-article.php?doi=brj.2021.10.17 KW - Anatomy KW -leaf KW -morphology KW -Liquidambar orientalis KW -Platanus orientalis KW -Turkey AB - In this study, anatomical characteristics of two species, Liquidambar orientalis and Platanus orientalis were investigated by examining the samples taken from dried drugs, under the light microscope. The anatomical structures of these two species, naturally occurring in Turkey have similar morphological features. They were examined in detail and the systematic characteristics were revealed. The mesophyll type of the leaves is dorsi-ventral and similar in both species. However, it is noted that the palisade parenchyma sequence was 2-3 layers at the L. orientalis samples while it was only monolayer in the P. orientalis ones. The stoma type was seen as anomocytic type (Ranunculous type) in the Platanus samples while it was a paracytic type (Rubiaceous type) in Liquidambar specimens. The mean tracheal diameter of P. orientalis in leaf lamina was 35.6 μm while that of L. orientalis was 17.6 μm. This value was estimated to be 29 and 10.2 μm in the petioles of Platanus and Liquidambar, respectively. In conclusion, the trachea diameter was measured wider in P. orientalis than that in L. orientalis. The other detected anatomic characters between the two species are presented in tables while the biometric measurements of cells and tissues were conducted and supported by the obtained images. This work is the first comparative microscopic research that illustrates the leaf epidermal micro-morphology and micro-anatomy of the species L. orientalis and P. orientalis. ER -
