Abstract:
The seed morphology of 11 species of Silene was studied, utilizing light and scanning electron microscopes, to determine the significance of seed coat features as taxonomic characters. There are variation in particular surface features within some members of the genus. The superficial ridges and tubercules exhibit patterns are very helpful in determining relationships among some species. Seed shapes are reniform or reniform-circular. The colour of seeds is greenish or brown. Seed size varies from the 0.5-1.2 mm long. The lateral surface is flat or concave. The dorsal surface is concave grooved in all examined taxa except S. longiflora is convex. The periclinal walls are convex, granulate with tubercle in the central area; convex, granulate; flat, granulate or flat, smooth. The anticlinal walls are straight, S-undulate, U-undulate or V-undulate. The data of seed characters were numerically analyzed using SPSS program.
