Introduction: Smilax L. are climbing plants that two species of Smilax excels L. and Smilax aspera L. grow in Iran. Materials & Methods: In this study, morphological characters of vegetative and generative organs of 17 population of Smilax excelsa from Mazandaran province are studied for the purpose of distinguishing significant characters that effective in segregation of populations. The results were analyzed by SPSS (Ver. 16) software and dendrogram constructed using within group method. Results & discussion: The results have shown that characteristics such as Stem diameter, Stipule length and width max, Stipule length max/Stipule width max, Leaf shape, Leaf length and width max, Leaf length max/Leaf width max, Peduncle length, Inflorescent length max, Inflorescent peduncle length, Flower number in inflorescent and Berry length and width max are effective in taxonomic segregation of populations. Conclusion: The present results showed that there is leaf diversity among the studied populations and characters like Leaf shape, Leaf length and width max, Leaf length max/Leaf width max are variable between populations.

Plantago major and Plantago lanceolata are abundant species of Plantago in north of Iran which are recognized as valuable medicinal plants with antibacterial, anti-inflammatory and antioxidant effects. Therefore, in this study, eight populations of these two species were collected from different regions of the north of Iran and investigated in terms of phenols, flavonoids, anthocyanins, saponins, chlorophyll a and b, carotenoids, soluble sugars, total proteins. The results showed that P. lanceolata had more metabolites on average than P. major. The mean differences for phenols, anthocyanins, saponins, carotenoids and soluble sugars were statistically significant at the level of 0.05; so that the highest mean differences were for soluble sugars, saponins and phenols with 78.84±7.60, 3.83±0.68 and 3.55±0.85 mg/g dry weight, respectively. In addition, the results showed that both species of Lafur region had more phenols, saponins and soluble sugars compared to their other populations. Analysis of the essential oil of Masuleh populations showed that the metabolites in the essential oils of these two species were also different; the pulegon and palmitic acid were the main components of P. major whereas the D-carvone and adipic acid, dioctyl ester were the main components of P. lanceolata. It seems that phytochemical studies could probably be used in the taxonomy of these two species and other species of Plantago. These findings will help to select species and populations with higher metabolic content followed by optimal use in the food, pharmaceutical and health industries.

Ecotourism and ecological and conservational importance of Hyrcanian forests are among the most important reasons for studying arboreal species of Hyrcanian forests. The main purpose of this study is to explore genetic diversity of Carpinus orientalis in the study area; north of Iran, by using of morphological and SDS-PAGE of the seed storage proteins patterns. Seed samples were collected from different populations of provinces, Gilan, Mazandaran, Golestan and Khorassan-e-Shomali. The morphological studies performed by 28 characteristics analysis. Seed proteins extracted by Tris-Glycine buffer and then total protein quantified by Bradford assay and protein pattern of the populations was determined by SDS-PAGE technique. Morphological and bands electrophoresis patterns data were analyzed by PAST software. Results showed that, SDS-PAGE electrophoresis pattern of populations have 10 band polymorphisms. The maximum numbers of bands are related to Chalus and Kiasar populations, in the Mazandaran, and minimum numbers of bands are related to Chichal populations, in the Guilan. Resulted clusters from morphological and seed storage protein were different forms. Furthermore, the speed of morphological and genetic changes are not comparable.

The purpose in this research to investigate two species Pteris by anatomy method and evaluation of similarities and differences between them in the forests of northern Iran. Therefore, the populations of two species of the Pteris cretica and Pteris dentate were collected from forests of Mazandaran, Guilan and Golestan. The results of the findings show that these two species of ferns , based on the anatomy of the main components I, II and IV are different from each other , but based on other main components aren’t significantly different from each other. Also, the dentate species populations based on principal component except the sixth, no significant differences were observed, and that could indicate the presence of more than one sub- species of the dentate in northern Iran.The results show that two species of ferns, in terms of anatomy based on principal component first, second and fourth different together, but the other main components do not differ significantly. Also among the populations of Dntata based on principal component except the sixth, there was a significant difference that could indicate the presence of more than one subspecies of Dntata northern Iran.
