Phylogeny And Biogeography Of Wajira (Leguminosae): A Monophyletic Segregate Of Vigna Centered In The Horn Of Africa Region, Mats Thulin, Matt Lavin, Remy Pasquet, Alfonso Delgado-Salinas
Phylogeny And Biogeography Of Wajira (Leguminosae): A Monophyletic Segregate Of Vigna Centered In The Horn Of Africa Region, Mats Thulin, Matt Lavin, Remy Pasquet, Alfonso Delgado-Salinas
All Peer-Reviewed Publications
Evidence from chloroplast trnK and nuclear ribosomal ITS sequences and morphological data reveals that the monotypic legume genus Wajira is nested within a clade comprising the species of Vigna subgen. Macrorhynchus. This Wajira-containing clade is basally branching in a larger clade that contains many of the genera traditionally referred to as tribe Phaseoleae subtribe Phaseolinae. Wajira is thus recircumscribed to include Vigna subgen. Macrorhynchus. Given the heterogeneity of floral morphology of its constituent species, Wajira is apomorphically diagnosed by woody stems and a pollen brush that comprises an introrse linear array of unicellular hairs. This recircumscribed genus now comprises five …

Propagation Of Thornless Blackberries Utilizing Adventitious Shoots From Root Cuttings, Ellen Thompson, John R. Clark, Curt C. Rom
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Studies were conducted in early 2003 to determine the effect of root source and length on yield of adventitious shoots from root cuttings and on subsequent plant yield for University of Arkansas-developed thornless blackberries. In the first study, roots from ‘Arapaho’ and ‘Apache’ plants grown in an aboveground bed containing commercial potting soil were compared to field-grown roots. Bed-grown roots averaged 6.9 shoots per 15 cm root cutting while field grown roots averaged 3.4. ‘Apache’ produced more shoots/root cutting compared to Arapaho, (5.9 vs. 4.4 shoots/root cutting, respectively). In a comparison of 15- vs. 30-cm-long root cuttings of ‘Apache’, ‘Arapaho’, …

Evaluation Of Post-Harvest Disease Resistance In Blackberry Genotypes, John-Paul Kidd, John R. Clark, Patrick Fenn, Barbara Smith
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Forty-nine blackberry genotypes (19 cultivars and 30 breeding selections) were evaluated for post-harvest fruit-rot resistance in June and July 2003. Fully mature, undamaged berries were harvested on two dates for each genotype at the University of Arkansas Fruit Substation, Clarksville. After transporting in chilled coolers back to the Plant Pathology Department in Fayetteville, two replications of 10 berries of each genotype were placed in a high-humidity chamber for 3 d (21-23°C; 16-h daylength). This provided a total of four replications for each entry across the two harvest dates. Natural inoculum from the field provided the post-harvest pathogens, and no additional …
Recent Developments In International Biological Nomenclature, Werner Greuter
Recent Developments In International Biological Nomenclature, Werner Greuter
Turkish Journal of Botany
After a period of several decades of general neglect, biological systematics and taxonomy are again surfacing to the awareness of the scientific community and of policy makers. This we owe to the fact that they are the core disciplines of biodiversity research, now perceived to be a priority task in view of the impending threat of loss through extinction of a great number of species, and the wholesale destruction of ecosystems. Yet the renaissance of systematics and taxonomy is hampered by the inadequacy of the traditional rules governing the formation and use of scientific names of organisms. Names are a …
The Genus Crataegus L. (Rosaceae) With Special Reference To Hybridisation And Biodiversity In Turkey, Ali̇ Arslan Dönmez
The Genus Crataegus L. (Rosaceae) With Special Reference To Hybridisation And Biodiversity In Turkey, Ali̇ Arslan Dönmez
Turkish Journal of Botany
The genus Crataegus L. has approximately 200 species worldwide. However, the number of the species is increased to 1200 species by some taxonomists. Traditionally, the genus is placed in the subfamily Maloideae and it is closely related to the genera Pyracantha M.Roem., Mespilus L. and Hesperomeles Lindl. The latest phylogenetic analysis of the genus shows that it is closest to the genus Osteomeles Lind. Crataegus is divided into 40 sections by various taxonomists. The genetic diversity centre of the section Crataegus ranges from Turkey to Iran. According to field observations in Turkey, new diversity centres are proposed. The latest studies …
The High Mountain Vegetation Of Turkey - A State Of The Art Report, Including A First Annotated Conspectus Of The Major Syntaxa, Gerald Parolly
The High Mountain Vegetation Of Turkey - A State Of The Art Report, Including A First Annotated Conspectus Of The Major Syntaxa, Gerald Parolly
Turkish Journal of Botany
This contribution spotlights the present research on the (oreal) subalpine to subnival mountain vegetation of Turkey. It concisely compiles our present knowledge, which is very heterogeneous in geographical terms. The situation is comparatively good in NW and W Anatolia and the western half of the Taurus range, from where a first consolidation stage can be reported. By contrast, the E Taurus remains a largely unexplored area. The Pontic chains have hitherto attracted a few local researchers only, and those important pioneering accounts cover less than half of the vegetation types actually present. The results of the last years' field work …
Biology Of The Central Desert Of Oman, Shahina A. Ghazanfar
Biology Of The Central Desert Of Oman, Shahina A. Ghazanfar
Turkish Journal of Botany
A biological survey of the central desert of Oman was done using long distance transects. Vegetation was sparse and consisted of 200+ plant species, 22 species of mammals, 17 species of reptiles and amphibians, and more than 50 species of birds (migratory and resident). Three main vegetation types were identified based on ground substrate and the dominance of species. These were communities with Acacia Willd., Zygophyllum L., and open woodlands of Prosopis cineraria (L.) Druce. Over-grazing and development in the central desert has led to concerns over the conservation of the desert ecosystem in Oman.
Life Strategies And Adaptations In Bryophytes From The Near And Middle East, Harald Kürschner
Life Strategies And Adaptations In Bryophytes From The Near And Middle East, Harald Kürschner
Turkish Journal of Botany
A review article on life strategies and ecomorphological adaptations (xerothalloid and xeropottioid life syndromes) of bryophytes is given, based on the hitherto known and analysed terrestrial, saxicolous and epiphytic communities of the Near and Middle East. The examples given impressively demonstrate common adaptive trends that arise convergently but independently in unrelated taxa when they evolve under similar habitat conditions. These functional types are important for the establishment, habitat maintenance and dispersal of species and indicate the relationships between site ecology, niche differentiation and species evolution. Their differentiation is a prime example of parallel evolution.
On The Distribution And Relationships Of The South-West Asian Species Of Eryngium L. (Apiaceae-Saniculoideae), Arno Worz
Turkish Journal of Botany
This paper deals with the Old World species of Eryngium L. which grow mostly in regions with a Mediteranean type climate. Two centres of diversity are visible: one in the Western Mediterranean (Iberian Peninsula, Morocco), and the other one in South-West Asia. Distribution maps are presented for several species from South-West Asia, which is probably the genus' most important centre of diversity. A preliminary new classification of the genus Eryngium is presented, including a new combination (Eryngium subgenus Fruticosum (Wolff) Wörz stat. nov.). Both the species and the sectional diversity are conspicuously present in Turkey, where 9 of 14 sections …

The Sections Of Astragalus L. With Bifurcating Hairs In Iran, Farrokh Ghahremaninejad
Turkish Journal of Botany
In this study Astragalus L. with bifurcating hairs in sectional levels in Iran are discussed (subgenus Cercidothrix Bunge). This subgenus has more than 800 species in the Old World. Major areas of species endemism for this subgenus occur in Turkey, Iran, Kazakhstan and Afghanistan. Iran, with 158 species, is one of the most important centres of diversity. Leucocercis Bunge is the only endemic section for Iran, although other sections have some species in different countries. Thus having a knowledge of the distribution quality in other areas is also important. In reality, this study is part of the author's research on …

Computer Technology For The Future Of Sw Asiatic Botany, R. J. Pankhurst
Turkish Journal of Botany
Much computer software already exists for floristic and monographic studies. Database software can hold all the data required for a Flora, and can process it much more accurately. The fundamental data tables are those for names, authorities, people, specimens, bibliography, geography and distribution. To these can be added other data such as descriptions, keys, images, maps, chromosomes and vernacular names. The same data system can be used for collection management and making herbarium labels. It is very important to use data standards such as for books, journals and authorities. Computerised descriptions and keys can also be constructed and held in …

A New Record For The Flora Of Turkey: Ambrosia Tenuifolia Spreng. (Compositae), Lütfi̇ Behçet
A New Record For The Flora Of Turkey: Ambrosia Tenuifolia Spreng. (Compositae), Lütfi̇ Behçet
Turkish Journal of Botany
Ambrosia tenuifolia Spreng. (Compositae) is a new addition to the flora of Turkey from Malatya (in the East Anatolia region). The specimens collected from Malatya have different properties from the known diagnostic characteristics of the species. A. tenuifolia is a monoecious plant without glands. Its female capitula are in the axils of the upper leaves in its original description, but some of our specimens have only female capitula (female capitula in terminal racemes and lower parts of the racemes bracteate, but upper parts ebracteate) and there are many glands particularly on the tops of their fruits. The diagnostic characteristics, ecology …

Pollen Morphology Of Egyptian Malvaceae: An Assessment Of Taxonomic Value, Salah M. El Naggar
Pollen Morphology Of Egyptian Malvaceae: An Assessment Of Taxonomic Value, Salah M. El Naggar
Turkish Journal of Botany
The pollen morphological characteristics of 21 species of Egyptian Malvaceae belonging to 10 genera: Abelmoschus Medik., Hibiscus L., Gossypium L., Lagunaria L., Abutilon Mill., Sida L., Malva L., Lavatera L., Alcea L. and Malvaviscus Cav., were investigated by light and scanning electron microscopy. The pollens were examined and described in each genus. The results demonstrated that pollen morphological characteristics, principally pollen shape, size, aperture characters and exine sculpture and structure, are taxonomically important. The pollen results are discussed with reference to current systematic treatments of Malvaceae.
Value Of Trichome Characteristics For The Separation Of Bifurcating Hairy Astragalus L. (Fabaceae) At The Sectional Level, Farrokh Ghahremaninejad
Value Of Trichome Characteristics For The Separation Of Bifurcating Hairy Astragalus L. (Fabaceae) At The Sectional Level, Farrokh Ghahremaninejad
Turkish Journal of Botany
The attachment of hairs in sections of Astragalus L. may be either basal or lateral (bifurcate). This study focuses on Astragali with bifurcating hairs in the Old World (subgenus Cercidothrix Bunge). In this study, it appears that the ratio of hair arm length, and hair form and length are usually stable at the sectional level. The proposition of uniting some sections based on morphological characters is confirmed by hair characters; for example, uniting sections Tamias Bunge, Acantherioceras Rech. f. and Pseudoerioceras Ulzijchutag with Erioceras Bunge. The most important characters in the separation of the sections are macromorphological, but hair characters …
