A biosystematical investigation on Silene L. species in north-east of Iran.

摘要

In present research anatomical and palynological studies carried out seven species of Silene which growing in north-east of Iran. These species belonged to four sections including Sclerocalycinae, Melandriformes, Auriculatae and Conoimorpha. For comparative anatomy studying, cross sections from stem and leaf were prepared using microtome and differential staining. The characters of secondary xylem and epidermal cell in leaf were studied. For palynology studying, after extraction of the pollen and acetolysis, the ornamentation of the pollen were investigated. The results of anatomy showed, presence of scleroid and fiber, spiral and reticulate vessel. The arrangement of vessel was radial chain pore, solitary and cluster. The arrangement of mesophyll was dorsi-ventral and isolateral. The pollen was spheroid, pantaporate, inaperture, tectate. Finally, a correspondence between morphology and palynology characters was observed.
