Nutrient Dynamics Of Olea Europaea L. Growing On Soils Derived From Two Different Parent Materials In The Eastern Mediterranean Region (Turkey), Hüsni̇ye Aka Sağliker, Cengi̇z Darici
Turkish Journal of Botany
Olea europaea L. (olive tree, Oleaceae), an important tree in the Mediterranean region, adds considerable amounts of leaf litters to soils, which may help in maintaining soil productivity. The aim of this study was to investigate temporal changes in the carbon (C), nitrogen (N), phosphorus (P) and potassium (K) contents of leaves, shoots, leaf litters and soils together with the amounts of leaf litters and humic and fulvic acids in the soils of olive trees growing on both marl and conglomerate parent materials in the Eastern Mediterranean region (Turkey). The element contents of leaf, shoot, leaf litter and soil samples …

Evaluation Of Diagnostic Reproductive And Vegetative Characters Among Tetraploid Triticum L. Species (Poaceae; Triticeae) In Iran, Navaz Kharazian, Mohammad Reza Rahiminejad
Evaluation Of Diagnostic Reproductive And Vegetative Characters Among Tetraploid Triticum L. Species (Poaceae; Triticeae) In Iran, Navaz Kharazian, Mohammad Reza Rahiminejad
Turkish Journal of Botany
This study concerns the evaluation of 19 vegetative and reproductive characters (7 qualitative and 12 quantitative) among 45 accessions belonging to wild and cultivated tetraploid Triticum L. species: T. turgidum L., T. durum Desf., T. dicoccum (Schrank) Schrebler and T. dicoccoides (Koern. ex Aschers. et Graebn.) Aaronsohn, occurring in Iran. The results of this study show that T. turgidum is a distinct species from T. durum, and T. dicoccum showed high similarity to T. dicoccoides. The strong relationship between the latter pair of species may result from a high degree of gene flow between them. The diagnostic characters between T. …

Giemsa C-Banded Karyotypes Of Vicia Cracca L. Subsp. Cracca And V. Bithynica L., Hüseyi̇n İnceer, Sema Hayirlioğlu Ayaz
Turkish Journal of Botany
The distribution of heterochromatin on the chromosomes of V. cracca L. subsp. cracca (2n = 14) and V. bithynica L. (2n = 14) was established with the aid of the C-banding technique. The chromosomes of both species have centromeric C-bands. When compared, prominent bands at the ends of the short arms on 4 chromosomes of V. cracca subsp. cracca were observed, while in V. bithynica only 1 chromosome had a prominent band at the end of the long arm. The C-banding patterns in the 2 species were different, and it was determined that heterochromatic regions were more dense on the …

Turkish Journal of Botany
The endemic Onosma bracteosum Hausskn. & Bornm. (Boraginaceae) was investigated morphologically, anatomically and ecologically. It has setae with tuberculate bases. The stem is 15-35 cm tall and erect. The leaves are equifacial and amphistomatous. Stomata cells are anisocytic and anomocytic. The stomata index is 21.25 for the upper epidermis and 25 for the lower epidermis. This plant generally prefers sandy-loamy, sandy-clayey and loamy soils. In the soil samples, the N (23%), P (26%) and K (27%) concentrations were lower in the generative periods than in the vegetative periods.

Post-Fire Dynamics Of Cistus Spp. In A Pinus Brutia Forest, Çağatay Tavşanoğlu, Behzat Gürkan
Post-Fire Dynamics Of Cistus Spp. In A Pinus Brutia Forest, Çağatay Tavşanoğlu, Behzat Gürkan
Turkish Journal of Botany
The population dynamics of 2 species of Cistus L. (C. salviifolius L. and C. creticus L.) were studied along a post-fire successional gradient in Pinus brutia Ten. forests in Marmaris National Park, Turkey. The population density of Cistus spp. was 16 individual m^{-2} at the end of the first year after fire and then decreased exponentially (r^2 = 0.926, P < 0.001) the second year after fire to later successional stages. Total projected foliage cover of Cistus spp. was 26% by the end of the first year after fire, it increased to approximately 38% during the second year after fire and decreased linearly (r^2 = 0.872, P < 0.01) beyond this time. Rates of establishment of Cistus spp. were high in the first year after fire but were low in subsequent years and most of the Cistus plants flowered during the second year after fire. There was a significant positive relationship between the density of new seedlings of Cistus and cover of Pinus brutia trees in the sixth year after fire (r^2 = 0.242, P = 0.002). Seed yield of Cistus was reduced due to predation of seed capsules by Bruchid insects. Both species of Cistus were shown to be typical post-fire colonisers in terms of timing of recruitment and post-fire population dynamics. The major factors responsible for the decrease in density of seedlings of C. salviifolius and C. creticus are likely to be the mortality of young seedlings due to summer drought and competition among seedlings and with P. brutia trees. It is suggested here that the species considered have fire-dependent establishment behaviour and an increase in population is restricted to early post-disturbance in P. brutia forests in Turkey, as in other Mediterranean regions.

Modern Approaches To Floristics And Their Impact On The Region Of Sw Asia, Vernon Hilton Heywood
Modern Approaches To Floristics And Their Impact On The Region Of Sw Asia, Vernon Hilton Heywood
Turkish Journal of Botany
Attitudes to floristics have changed considerably during the past few decades as a result of increasing and often more focused consumer demands, heightened awareness of the threats to biodiversity, information flow and overload, and the application of electronic and web-based techniques to information handling and processing. This paper will examine these concerns in relation to our floristic knowledge and needs in the region of SW Asia. Particular reference will be made to the experience gained from the Euro+Med PlantBase project for the preparation of an electronic plant-information system for Europe and the Mediterranean, with a single core list of accepted …
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 …
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.
