New Morphological Characters For Some Erysimum (Brassicaceae) Species, Bi̇rol Mutlu
Turkish Journal of Botany
Trichome shapes were investigated on the outer and inner surfaces of fruit valves of 43 species of Erysimum L., 20 of which are endemic to Turkey, by light microscopy (LM) and scanning electron microscopy (SEM). Five species, Erysimum sorgerae Polatschek., E. huber-morathii Polatschek, E. cheiri (L.) Crantz, E. repandum L. and E. vuralii Yild. were identified, in which there are trichomes on the inner surface of fruit valves, which was determined for the first time in these species. Two morphological distinct types of trichomes were observed on the inner surfaces of the fruit valves of E. huber-morathii and E. repandum, …

Turkish Journal of Botany
The genus Cyclotrichium, a member of the tribe Mentheae subtribe Menthinae (Lamiaceae, Nepetoideae), was analysed with respect to morphological revision, phylogenetic analysis, and cytogenetic properties. All species of the genus were investigated for morphological characters and ITS (internal transcribed spacers) of nrDNA sequence comparison (except C. hausknechtii for ITS). Six members of the genus were also analysed for chromosome numbers. The combined results strongly suggested that Cyclotrichium is a separate genus in Nepetoideae with distinct morphological, phylogenetic, and cytogenetic characteristics. For intrageneric phylogeny of Cyclotrichium, 3 groups were recognised: 1. C. niveum; 2. C. origanifolium; and 3. the remaining 6 …

Turkish Journal of Botany
Allium dentiferum Webb & Berthel and Allium dodecanesii Karavokyrou & Tzanoudak were collected during a floristic study of South Anatolia. A. dodecanesii is reported as a new record for the flora of Turkey. Although collected earlier by Aznavour, Bothmer, and Brullo, specimens of A. dentiferum were misinterpreted and the species was thus not recorded for the flora of Turkey. We provide drawings and photographs of the species, and maps of their distribution in Turkey.

Comparative Rapd Analysis And Pollen Structure Studies Of Bellis Perennis L., Nesli̇han Kavalcioğlu, Leyla Açik, Nur Münevver Pinar
Turkish Journal of Botany
Random amplified polymorphic DNA (RAPD) is one of the easiest and most commonly used molecular techniques for genetic variability analysis. In the present study, the genetic diversity of analysis of Bellis perennis L. collected in 4 Turkish geographical locations was investigated by RAPD-PCR analysis. In addition to RAPD, pollen analysis of the 4 plant populations was also conducted. Out of 40 RAPD primers tested, 12 exhibited distinct banding patterns showing 45% to 79% polymorphism. Plants from these 4 localities were almost the same morphologically. Considerable differences were observed in the RAPD profile and pollen shape of plants from the Rize/Dereköy …
Classification Of Some Plant Species According To Grime’S Strategies In A Quercus Cerris L. Var. Cerris Woodland In Samsun, Northern Turkey, Mahmut Kilinç, Nesli̇han Karavi̇n, Hamdi̇ Güray Kutbay
Turkish Journal of Botany
This study was carried out on 2 permanent plots of Quercus cerris L. var. cerris woodland in the Kurupelit region of Samsun, northern Turkey. Grime's CSR strategies were determined for 85 plant species from the 2 study plots (61 and 50 species from plot 1 and plot 2, respectively) according to the method that was applied. Most of the plant species in both plots had secondary and tertiary strategies, and this suggests that plants were exposed to more than one pressure factor. In both plots, CR (competitor-ruderal) was the most common strategy.

Yield Potential And Resource-Use Efficiency Of Maize Systems In The Western U.S. Corn Belt, Patricio Grassini
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
Maize demand for food, livestock feed, and biofuel is expected to increase substantially. The Western U.S. Corn Belt accounts for 23% of U.S. maize production, and irrigated maize accounts for 43 and 58% of maize land area and total production, respectively, in this region. The most sensitive parameters (yield potential [YP], water-limited yield potential [YP-W], yield gap between actual yield and YP, and resource-use efficiency) governing performance of maize systems in the region are lacking. A simulation model was used to quantify YP under irrigated and rainfed conditions based on weather data, soil properties, and crop management at 18 locations. …

The species composition and diversity of the epipelic algae of Balık Lake were investigated between May and October 2008. A total of 39 taxa were determined, and Cyclotella meneghiniana, Craticula cuspidata, Closterium strigosum, Cocconeis placentula var. euglypta, and Amphora ovalis were the most conspicuous algae, regarding frequency of occurrence and relative abundance in the epipelic algal flora. While the highest total cell number of the epipelic community was 26,214 cells/cm^2 in October, the lowest was 23,644 cells/cm^2 in July. The highest species diversity index (H^{'}) value was 2.26, in June.

Male Individuals In Cultivated Fritillaria Persica L. (Liliaceae): Real Androdioecy Or Gender Disphasy?, Elisa Mancuso, Lorenzo Peruzzi
Turkish Journal of Botany
In the last twenty years the growing number of studies about the reproductive biology in angiosperms has brought to light new cases of andromonoecy and androdioecy, the rarest sexual models among flowering plants. Female-sterile sexual systems, especially within order Liliales and family Liliaceae, often seem to occur in the particular form of size/age dependent sex allocation, known as "gender disphasy". The presence of male individuals of Fritillaria persica (Liliaceae) is here documented. Comparative morphological and functional sexual expression of this species, among males and hermaphrodites, was investigated by means of flowers counting, morphometric measurements of plants and pollen-grains, pollen viability …

To help in the clarification of the taxonomic status of Elymus L. and related genera Agropyron Gaertn., Leymus Hochst., Hordelymus (Jess.) Harz, and Brachypodium P.Beauv., the sequence diversity in the internal transcribed spacer (ITS) region of nuclear ribosomal DNA was studied. ITS data of 64 Triticeae accessions including 40 Elymus, 12 Agropyron, 7 Leymus, and 4 Hordelymus, and 1 Brachypodium as an out-group were analysed. The molecular diversity statistics indicated that the most diverse genus is Elymus among the studied genera. The constructed phylogenetic tree by the maximum parsimony method revealed that one specimen of Elymus, E. pycnanthus (Godr.) Melderis, …

This study describes the karyotypes of 10 Turkish species of Trigonella L. belonging to section Cylindricae Boiss. (Leguminosae). Excluding the karyotypes of T. velutina Boiss. and of T. sibthorpii Boiss., which were previously studied, all of the other 8 species were studied here for the first time. The species of the section were gathered from different localities in Turkey, and it was determined that the somatic chromosome numbers for all species were the same (2n = 16). Also, satellite metaphase chromosomes were determined in T. velutina and T. strangulata.

Turkish Journal of Botany
Pollen morphology of the 13 taxa of Scorzonera L. (Asteraceae) from Turkey was investigated by using light (LM) and scanning electron microscopy (SEM). As a result of LM and SEM observations, it was found that the pollen types are generally isopolar, radially symmetric, triangular in polar view, and lophate, with lophae ornamentations that are echinate-perforate and an exine thickness ranging from 6.99 to 11.82 µm. The present study found that the lacunae ornamentation of S. laciniata subsp. laciniata and S. tomentosa is perforate-microrugulate, that of S. suberosa and S. cinerea is perforate-microreticulate, that of S. pseudolanata is perforate-psilate, and that …

Turkish Journal of Botany
Common bean (Phaseolus vulgaris L.) cultivars (cvs) (Göynük 98, Karacaşehir 90, Şehirali 90, ES 855, and Yunus 90) were subjected to drought stress in order to assess the levels of drought tolerance through the analysis of growth parameters, leaf water potential (\psi_{leaf}), stomatal conductance (g_s), chlorophyll (chl) content, and lipid peroxidation. Significant differences were recorded among cultivars in most traits. Yunus 90 was identified as the most tolerant, and Karacaşehir 90 was the most sensitive. Furthermore, the changes in antioxidant enzyme activities, H_2O_2 content, and Photosystem II were investigated under drought stress, where Antioxidant enzyme activities increased while H_2O_2 contents …
