In this study the present taxonomy of Turkish Iris L. were revised by using phenetic clustering method based on external vegetative and floral morphological characters of herbarium and fresh specimens. For this, 79 morphological characters for each taxon within the genus Iris L. were extracted and the data were analyzed by the NTSYSpc 2. 1 computer package by UPGMA method. In addition to this, cytological and biogeographical data of the taxa were also integrated into the new classification. The results of this study showed that subgeneric divisions in all of the four subgenera are required. Within the subgenus Limniris a new section of Sphenostylis and within the subgenus Scorpiris a new section of Anatolica were established. Moreover, the serial status of taxa within the subgenus Limniris were rearranged by placing them under four subsections. The previous series Spuria were divided off and a new subseries was created. Within the section Iris a new subsection Pumilae to include dwarf irises and two new series were established. A new subsection and two new series were established within section Oncocyclus and taxa were placed within these ranks by employing new floral morphological criteria. The sectional status of the subgenus Hermodactyloides were modified by replacing the taxa into the previous ranks. As an another result of this study a new key for the Turkish irises together with a new description for each of the taxa were also presented. It was also found that the characteristics of structure and biology of the vegetative organs such as rhizome and bulbs, and stem structure and baranching pattern are as important as the floral characters in determining the limits of the taxa within the genus and the distribution of its species amongst subgenera, sections and other groups.

Molecular phylogenetics of Turkish Salix L. species
Acar, Pelin; Kaya, Zeki; Department of Biology (2017)
Chloroplast (trnT-F, matK and rbcL) and nuclear genome (ITS) regions were used to explore the evolutionary relationships of Salix species which are native to Turkey. Morphological analysis with the utilization of Principal Component Analysis (PCA) was also carried out. Such a combined sequence data from cpDNA and nrDNA genes enabled reliable subgenus-level classification of Turkish willows (subgenus Salix and Vetrix). Morphological and genetic results agree with traditional taxonomic concepts in clustering ...

For the first time the calyx, corolla and leaf micromorphology,...
Genetic control of rooting ability of lodgepole pine cuttings
Fries, A; Kaya, Zeki (1997-11-01)
This study evaluates the genetic control of rooting ability ex vitro for cuttings of lodgepole pine (Pinus contorta var. latifolia Engelm.). More than 200 clones from 21 full-sib families were studied during 4 yr in the greenhouse. Clonal averages in rooting frequency, root size score, shoot extension during rooting, and vitality score were calculated, together with variance components and phenotypic and genetic correlations among variables. Years, families within latitude of origin, clones within families ...
Genetic relationships among perennial and annual Cicer species growing in Turkey as revealed by allozymes
Sudupak, MA; Kence, Aykut (Springer Science and Business Media LLC, 2004-05-01)
Allozyme polymorphisms were used to assess genetic variation and relationships among ten Cicer species ( annuals and perennials) growing in Turkey. Using seven enzyme systems, 12 putative scorable loci were detected and surveyed for polymorphism in an accession collection including wild and cultivated forms. Variation was generally low within accessions and species, but common between species. Cluster analysis based on the pairwise genetic distance coefficients (Nei 1978) among accessions and species using ...
Morphology, anatomy and systematics of the genus Salvia l. (Lamiaceae) in East and Southeast Anatolia, Turkey
Kahraman, Ahmet; Doğan, Musa; Department of Biology (2011)
This study aims to revise the genus Salvia L. in East and Southeast Anatolia in Turkey on the basis of macromorphological, anatomical, palynological, mericarp micro-morphological, ecological and numerical analysis. Towards achieving this goal, about 2500 specimens of Salvia were collected and examined during extensive field studies between July 2005 and June 2009. The materials collected by other researchers either from Turkey or abroad were also investigated. The results of the taxonomic revision show that...
