Turkish Journal of Botany
A Turkish endemic, Erodium hendrikii Alpınar, was firstly described from NE Anatolia in 1994 based on insufficient specimens. In the present study, the description of this poorly known taxon was emended by adding several macro- and micromorphological traits of its leaf and fruit observed under LM and SEM. Furthermore, it was compared with the closely related species E. malacoides (L.) L'Her based on both morphological and molecular data and a modified identification key for the Flora of Turkey was prepared. The conservation status was also re-assessed according to the IUCN threat criteria.

Embryological And Cytological Features Of Gagea Bohemica (Liliaceae), Fi̇li̇z Vardar, Işil İsmai̇loğlu, Meral Ünal
Turkish Journal of Botany
The present study describes the developmental features of the embryo sac and ovular structures, particularly the obturator, during development in Gagea bohemica (Zauschn.) Schult. & Schult. f. The nucellar epidermis is poorly developed and composed of 1-2 layers of cuboidal cells. The tissue at the chalazal end of the nucellus differentiates into a hypostase. The micropyle is formed by the inner integument and composed of 4-5 cell layers that include starch grains. The functional megaspore results in an 8-nucleated embryo sac and conforms to a tetrasporic, Fritillaria L. type. Cytoplasmic nucleoloids consisting of protein and RNA are obvious during megasporogenesis. …

Anatomical Analysis Of Red Juniper Leaf (Juniperus Oxycedrus) Taken From Kopaonik Mountain, Serbia, Predrag Spasoje Vasic, Darko Vlajko Dubak
Turkish Journal of Botany
In this study, the anatomical characteristics of Juniperus oxycedrus (Cupressaceae) leaves from Kopaonik Mountain (Serbia) are analysed. The level of distinction between leaves taken from various altitudes (420-1420 m) was determined by analysing anatomical characters. The clear correlation between increase in altitude and change in anatomical characters of the leaves was not established by descriptive analysis. The leaves collected from plants growing at 620 m had the most prominent xeromorphic characteristics (thick cuticles and thick epidermis walls). The discriminant canonical analysis also showed a clear distinction between red common juniper from 420 m and the samples taken from different altitudes.

Turkish Journal of Botany
The role of smoke as a fire-related germination cue is well known in many parts of the world, including Mediterranean-type ecosystems; however, it has been neglected in the Mediterranean Basin (MB). We studied the germination response of 5 woody species found in the eastern MB (south-western Turkey) to smoke solutions derived from different plant species. Of the 5 species examined, 2 [Sarcopoterium spinosum (L.) Spach and Satureja thymbra L.] showed significant increments in germination percentage after smoke treatments compared to the control, while the remaining 3 [Calicotome villosa (Poir.) Link, Cistus salviifolius L., and Lavandula stoechas L.] did not. However, …

Induction Of Phytochelatin And Responses Of Antioxidants Under Cadmium Stress In Safflower (Carthamus Tinctorius) Seedlings, Shahram Namdjoyan, Shahrokh Namdjoyan, Hossein Kermanian
Turkish Journal of Botany
We investigated the role of antioxidant compounds (e.g.,\alpha-tocopherol, phytochelatins, glutathione, and other non-protein thiols) in the cadmium (Cd) tolerance of safflower (Carthamus tinctorius L. cv. Arak2811) seedlings exposed to different concentrations of Cd (0-100 \muM) for a week. A concentration- and tissue- dependent response to Cd was observed. Increasing Cd supply markedly reduced the dry weight of roots. Plants accumulated a substantial amount of Cd, especially in the roots. Levels of \alpha-tocopherol showed a significant increase with an increase in the concentration of Cd in leaves. Upon Cd exposure, \alpha-tocopherol levels followed a similar pattern in the root tissue with …

Turkish Journal of Botany
In this study, heavy metal (Cd, Cr, Cu, Mn, and Zn) contents of wild-growing mushrooms and soil samples collected from Bigadiç (Balıkesir) were determined. A total of 38 fungal taxa were found in the study area. Among the mushroom samples analysed, minimum and maximum metal contents were 0.11-2.58 mg kg^-1 for Cd, 1.01-19.55 mg kg^-1 for Cr, 2.61-72.44 mg kg^-1 for Cu, 1.38-47.52 mg kg^-1 for Mn, and 5.75-97.55 mg kg^-1 for Zn. For all elements, values are within the acceptable levels as reported by several researchers. Hohenbuehelia petaloides (Bull.) Schulzer had the lowest elemental composition for all elements. Metal …

Alcea L. is represented by 18 species and Althaea L. by 4 species in the Flora of Turkey. Seventeen species of Alcea and all species of Althaea were collected. One new cultivated record of Alcea was added. Contrary to the Flora of Turkey, the endemicity of Alcea apterocarpa (Fenzl) Boiss., Alcea calvertii (Boiss.) Boiss., and Alcea fasciculiflora Zohary has not been proved. The threat category of Alcea fasciculiflora and Alcea pisidica Hub.-Mor. has been changed to CR, while they were placed in DD according to the Red Data Book of Turkish Plants.

Turkish Journal of Botany
The aim of the present study was to determine the antioxidant system responses of a xerophytic plant to salinity and drought, which were not elucidated before. Physiological and antioxidant responses of the xerophytic plant Gypsophila aucheri Boiss. were investigated under salinity (100 and 300 mM NaCl) and drought (withholding watering) treatment for 2 weeks in a controlled growth chamber. Besides growth responses (relative growth rate (RGR)), superoxide dismutase (SOD), catalase (CAT), peroxidase (POX), ascorbate peroxidase (APX), and glutathione reductase (GR) activities, and SOD and CAT isoenzymes activities were determined under stress conditions. Moreover, the level of lipid peroxidation was determined …

Variations in the phytoplankton of Zayandeh-Rood Dam Lake were studied seasonally from September 2005 to August 2006 at 4 different stations. A total of 112 species and 53 genera belonging to 6 divisions were identified. The species belonging to Bacillariophyta, Chlorophyta, Cyanophyta, Euglenophyta, and Dinophyta were found frequently. Chrysophyta species were found in low numbers. Cyclotella meneghinina Kütz., a centric diatom, was the dominant species at all stations. The density of the phytoplankton was between 470 and 150,470 cells/cm^3. According to the Shannon-Weaver Index, the highest and the lowest diversities were determined in November and May, respectively. Regarding physico-chemical analysis …

Some physicochemical variables and climatic effects on the succession of a diatom community in the plankton of the pelagic zone of Lake Hazar, an alkaline soda lake, were investigated. Monthly diatom samples were collected from the surface water at western, central, and eastern pelagic areas of the ellipsoid-shaped lake using a plankton net from November 2004 to October 2005. When high temperature and pH levels prevailed in May and September, Epithemia, Rhopalodia, Cocconeis, and Cyclotella were dominant. Cymbella was dominant in early spring and late autumn, but was not significantly correlated with temperature or pH. The species of Gomphonema, Fragilaria, …

In this taxonomic study, myxomycetes of Tayfur Sökmen Campus (Hatay) were collected during 2010-2011. As a result of field and laboratory studies we reported 44 species of protosteliomycetes and myxomycetes. Three of these species (Diderma deplanatum Fr., Didymium megalosporum Berk & M.A.Curtis, and Lamproderma atrosporum Meyl.) are recorded for the first time from Turkey. Lamproderma atrosporum was treated with the moist chamber cultures method in the laboratory but Didymium megalosporum and Diderma deplanatum were determined naturally. The distribution, habitat, and collection numbers of the identified species are given.

This study examined the long-term patterns in vascular plant composition on three islands in Lake Winnipesaukee, NH. It also tested the role of island biogeography in ecology as it analyzed the effectiveness of a land use plan implemented on the islands. Samplings were made on the islands in the summer of 2011 and were compared to earlier samplings in 1978, 1991, and 2001. The flora was observed and measured in 25 permanent plots that were established on the three islands in 1978. The understory flora was measured by presence and percent cover and the overstory was measured by frequency and …
