Anatomical and Palynological Characteristics of Endemic Fritillaria gencensis Yıld., Kılıç & A.Demirpolat

Abstract

This study was carried out to determine the anatomical and palynological features of Fritillaria gencensis, a new species found in Turkey. Since endemic F. gencensis is a new species, no previous systematic research has been conducted on this species. In this study, the anatomical and palynological features of F. gencensis were evaluated to define the species in more detail. Anatomical examinations were made on the surface section of leaf and stem. In the trunk cross-section, the cortex cells are 3-7 layers. These cells are thin, parenchymal and have little or no intercellular spaces. 1-2 rows of collenchyma cells are seen below the cortex. In the upper and lower superficial sections taken from the leaf, the stomata index was 49.88% in the upper epidermis and 48.66% in the lower epidermis. Stomata are of the anomocytic type because there are no specific types of adjacent cells surrounding the stomata. As a result of palynological studies, the average of the polar axis, which is the long axis of the pollen, was 34.38 m, the equatorial axis was 24.23 m and the average thickness of the exine was 1.25 m. Pollen shape was prolate. Pollen ornamentation was reticulated. In this study, the anatomical and palynological features of the morphologically new F. gencensis species were determined and the differences supported by anatomy and pollen studies.
