Artvin, which is famous for greenery land, has a very rich flora in terms of plant diversity and richness. It has Blacksea climate and place in place has the Mediterranean climate (especially near Coruh River). Soğanlı village is located in the province of Artvin-Ardanuç. This village distance from the city center is 35 km and it has 850 m altitude. In this study, The floristic structure of the Artvin-Soğanlı Village is researched. And also the medicinal and aromatical plant taxa and their traditional usage of this region were investigated. Plants have been used for different purposes such as food, medicine, pesticide etc. for a long time. Local floristic investigation and individuals knowladge about the traditional usage of plant taxa are vital important issue because if these knowladge would not be transferred generation to generation, local traditional usage of plant taxa will be disappered. As a result of the study 189 naturally plant taxa were identified and families, scientific names, usage parts, traditional usage of these plant taxa, which had have ethnobotanical importance, were indicated.

Abstract:Forests not only produce wood raw material ecosystems, but also that have rich medicinal and aromatic plants. In addition to this situation, forests have been produced many goods and services. Regulation of protectionutilization balance with wood and non-wood herbal products is very important to these ecosystems. In order to ensure sustainable utilization of forest ecosystems, first of all, it is necessary to identify the natural resource components in these ecosystems. In this study, medicinal-aromatic plants of natural Scots pine (Pinus sylvestris L.) stands, which are a sensitive ecosystem, were investigated in 2013-2014. Pinus sylvestris has special ecological conditions in Sürmene-Çamburnu (Trabzon) region because in this region Pinus sylvestris is descending down to the beach. In the study, 81 (77%) out of 105 vascular plant taxa were found to have medicinal-aromatic potential. The parts of the identified plant taxa used for different medical and aromatic purposes are explained in detail. In addition, recommendations were made about regulation of utilization in sensitive ecosystems.

This study was performed to find out the vascular weed taxa of tea (Camellia sinensis (L.) Kuntze) plantations in Turkey and determine the critical control periods of the taxa which are negatively affect both of crop quality and yield. These taxa were determined with the studies and observations of authors both in tea plantations and local herbarium (KATO). A total of 114 native and naturalized/cultivated vascular plant taxa were found out as weeds in tea plantations. The most noxious weed, which were unintentionaly added to harvested shoots and negatively affected the tea quality, were underlined. The most commonly growing taxa in tea plantations in the region were: Pteridium aqulinum (L.) Kuhn., Smilax excelsa L., Alnus glutinosa (L.) Gaertn. subsp. barbata (C.A. Mey.) Yalt., Crassocephalum crepidioides (Bentham) S. Moore, Calystegia silvatica (Kit.) Griseb, Commelina communis L., Microstegium vimineum (Trin.) A. Camus., Oplismenus undulatifolius (Ard.) P. Beauw. and Rubus spp. A high number of the observed weed species are ecologically tolerated taxa which are naturalized in the region. Furthermore, of these taxa 9 are climbers and 14 are woody plants. The critical periods of weed control in tea plantations were derived from both literature and our ecological/phenological observatins in tea plantations.

In the present study, needle variation of Scots pine (Pinus sylvestris L., Pinaceae) populations in Turkey was investigated. From selected eight populations, a total of 1314 needles belonging to 206 trees were examined. Four morphological needle traits were measured and analyzed to describe the population diversity and differentiation. Analyzed morphological traits showed significant variability. The trees within populations differ significantly in all analyzed needle characteristics, while the differences between populations were significant for the three of four studied characteristics. Present findings revealed that needle length, needle width and the ratio of needle length to needle width showed clinal variation in response to altitudinal gradients. Populations from higher altitudes were characterized with the smaller and wider needles as compared to the populations from lower altitudes. The results of this study could be valuable baseline data for the development of more efficient management plans for this forest tree species.
