Abstract

Nerium oleander (Apocynaceae) which spread over a wide area along the Mediterranean coast, is an important indicator plant of Mediterranean elements. The objective of the current research was to reveal the altitude effect of N. oleander in the Middle-West Taurus region situated in Turkey. In this study, it is statistically evaluated that the micro morphological and anatomical changes observed in tissues of the leaves collected at different altitudes. Leaf structure of N. oleander demonstrated morphological, epidermal and anatomical alterations at various elevations. Statistical analysis was subjected to analysis of covariance (ANCOVA). According to the Levene test results, it is determined that the Wmed and Lmed averages of some anatomical parts such as spongy parenchyma cells, collenchyma and xylem layers, increase as the altitude escalates. This result has been supported by the correlative effect of locality and anatomical parts and it is significantly relating the measurement of Wmed (p = 0.000<0.05). In micro morphological studies, trichome density and cavities were seen in the stomatal crypt chamber, the sizes of the upper and lower epidermal cells and the structures of anticlinal walls were examined in the superficial incisions. Considering the altitudes starting from 3 m up to 898 m, it is observed that the trichomeson the leaf epidermal surface were observed to decrease as altitude increases, while any remarkable difference was not found for the trichomes located in the stomatal crypt. Notwithstanding, the crystals in the leaf mesophyll layer were more concentrated at low altitude (3 m) while abundance decreased at higher altitudes (898 m).
