An anatomical study of some species of Silene sect. Auriculatae on population level in Iran
Abstract:
Silene sect. Auriculatae is represented by 36 species including 22 endemic species, is the most important section of the genus in Iran. A comparative anatomical study of stem and leaf of S. renzii, S. microphylla, S. parjumanensis, S. persica, S. rhynchocarpa, S. nizvana, S. gertraudiae and S. sojakii was performed at the population level from Iran. 19 quantitative and qualitative anatomical features of stem and 25 characters of leaf were measured on the 5 well prepared photographs. The taxa studied are distinguished by some anatomical features such as; cuticle thickness, dimension of epidermal cells, the location and dimension of crystal, the thickness of cortex parenchyma, the thickness of sclerenchyma layer, the number of vascular bundle in stem, the arrangement of phloem and xylem, the thickness of xylem and phloem tissue, the thickness of pith and mesophyll thickness. The results of the present research in accordance with the morphological study are confirmed the absent of S. rhynchocarpa in Iran, the ambiguity in nomenclature of S. renzii at intraspecific level and the distinction of Yazd population of S. microphylla from Semnan population.
