Alucra (Giresun)-Şiran-Torul (Gümüşhane) arasında kalan bölgenin florası

Bu arastirma, Giresun ve Gumushane illerinin sinirinda bulunan Alucra, Şiran ve Torul Ilcelerinin arasinda kalan bolgenin florasinin ortaya koyulmasi amaciyla gerceklestirilmistir. Arastirma bolgesi yan-kurak alt soguk ve buzlu Akdeniz iklimlerinin etkisi altindadir. Arastirma bolgesinden toplanan 619 bitki orneginin degerlendirilmesi sonucunda 61 familyaya ait 205 cins ve 423 tur ve turalti takson tespit edilmistir. Arastirma alanindaki en zengin familya Asteraceae ve en zengin cins Ise Caryophyllaceae familyasindan Silene olarak belirlenmistir. Alandan toplanan turlerin 5? tanesi endemik olup bunun butun turlere oram %13.48'dIr. Turlerin floristik bolgelere dagilimi ise su sekildedir; tran-Turan; %26.47, Avrupa-Sibirya; %10.41, oksin; %3.78, Dogu Akdeniz; %1.89, Akdeniz; %1.66, Hirkano-Oksin; %0.94, Genis Yayilisli ve Bilinmeyen; %54.85* dir. AbstractIn this research it was aimed to carry out the floristic characteristics of the area at the border of Giresun and Gumushane between Alucra-Şiran and Torul. The study area is under the effects of Mediterranean climate with a semi-arid lower cold and glacial type. As a result of identification of the collected specimens, 423 taxa at specific and sub specific ranks have been determined from the area which belong to 61 families and 205 genera. The richest family and the richest genus of the research area were found as Asteraceae and Sitene respectively. 55 of the collected plant species were endemic and its ratio to total is 13.48 %.The distribution of species according to the phytogeographical regions is as follows: Irano-Turanuui; 26.47%, Euro-Siberian; 10.41%, Euxine; 3.78%, East Meditterranean; 1.89%, Meditterranean; 1.66%, Hyrcano-Buxine; 0.94%, Widespread and Unknown; 54.85%.
