Leaf Epidermis Morphology Of Some Onosma (Boraginaceae) Species From Turkey, Öznur Ergen Akçi̇n, Gülcan Şenel, Yaşar Akçi̇n Jan 2013

Leaf Epidermis Morphology Of Some Onosma (Boraginaceae) Species From Turkey, Öznur Ergen Akçi̇n, Gülcan Şenel, Yaşar Akçi̇n

Turkish Journal of Botany

The leaf epidermis of 14 Onosma L. species was examined by light and scanning electron microscopy (SEM). The leaf characters studied showed some variations. Morphologic features of the epidermal cells such as shape, structure of the anticlinal walls, stomatal size, outer stomatal rims, peristomatal rims, and apertures were summarised in the examined taxa. It was found that these characters are variable in the genus but usually they are stable within a species. Epidermal cells of the investigated taxa are polygonal, elongated, or irregular. Anticlinal walls of the epidermal cells are generally straight to curved and repand. Apertures are long, ellipsoidal, …


Micromorphological And Preliminary Phytochemical Studies Of Azadirachta Indica And Melia Azedarach, Samineh Jafari, Soodabeh Saeidnia, Mohammad Reza Shams Ardekani, Abbas Hadjiakhoondi, Mahnaz Khanavi Jan 2013

Micromorphological And Preliminary Phytochemical Studies Of Azadirachta Indica And Melia Azedarach, Samineh Jafari, Soodabeh Saeidnia, Mohammad Reza Shams Ardekani, Abbas Hadjiakhoondi, Mahnaz Khanavi

Turkish Journal of Botany

Azadirachta indica A.Juss. and Melia azedarach L. are 2 closely related species from Meliaceae that are considered noteworthy medicinal plants in the world and have very often been confused with each other. Various evaluations like organoleptic and microscopic characteristics, preliminary phytochemical screening, and fluorescence analysis were carried out on the pulp, husk, leaves, and seeds of both plants in powdered form to establish appropriate data that can aid rapid and easy differentiation between them. The results showed that these 2 species can be differentiated macroscopically and microscopically but tests of phytochemical analysis were not absolutely felicitous for this aim. In …


Comparative Anatomy Of Elaiophores And Oil Secretion In The Genus Gomesa (Orchidaceae), Natalia Elva Gomiz, Juan Pablo Torretta, Sandra Silvina Aliscioni Jan 2013

Comparative Anatomy Of Elaiophores And Oil Secretion In The Genus Gomesa (Orchidaceae), Natalia Elva Gomiz, Juan Pablo Torretta, Sandra Silvina Aliscioni

Turkish Journal of Botany

Oils are atypical floral rewards in Orchidaceae and are produced by epidermal glands called elaiophores. Flowers of many members of the subtribe Oncidiinae either produce oil or mimic oil-producing flowers of Malpighiaceae. We focus our research on 3 species of Gomesa, namely, G. flexuosa, G. riograndensis, and G. varicosa in order to investigate the presence of elaiophores, their micromorphology and internal structure, and the process of oil secretion. Elaiophores were located using Sudan III and their internal and external features examined using light and scanning electron microscopy, respectively. The presence of elaiophores was confirmed for regions of calli that are …
