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
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.

The Diatoms Of Asartepe Dam Lake (Ankara), With Environmental And Some Physicochemical Properties, Tahi̇r Atici, Emi̇ne Olcay Obali
Turkish Journal of Botany
The shoreline benthic diatoms of Asartepe Dam Lake were identified from different habitats (epipelic, epiphytic, and epilithic) at 7 sampling stations between April 2003 and June 2004. In the investigation, a total of 93 taxa were identified. Of those, Cymbella affinis Kütz., Navicula radiosa Kütz., Ulnaria ulna (Nitzsch) Compère, Pinnularia borealis Ehrenb., Amphora ovalis (Kütz.) Kütz., Cyclotella ocellata Pant. and Nitzschia dissipata (Kütz.) Grunow were observed and abundant at all stations. Some physical and chemical water quality parameters were measured and correlated with biological parameters.

Turkish Journal of Botany
Hypocotyl explants of 3 flax cultivars were cultured for adventitious shoot regeneration in 3 different ways. Two pretreatment applications were compared with the routinely applied conventional regeneration protocol of culturing explants directly on Murashige and Skoog (MS) medium containing 1 mg L^{-1} 6-benzylaminopurine (BAP) and 0.02 mg L^{-1} naphthalene acetic acid (NAA). In the first pretreatment application, explants kept in a sterile cabin under an air flow for 30 min were immersed in MS solution containing 1 mg L^{-1} BAP and 0.02 mg L^{-1} NAA for 15 min; then pretreated explants were cultured on MS medium without any growth regulators …

Palynological Observations On The Genus Scorzonera L. (Asteraceae) From North-East Anatolia (Turkey), Zafer Türkmen, Serdar Makbul, Kami̇l Çoşkunçelebi̇, Osman Beyazoğlu
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 …

Response Of Photosynthesis In The Leaves Of Cucumber Seedlings To Light Intensity And Co2 Concentration Under Nitrate Stress, Xiaoyu Yang, Xiufeng Wang, Min Wei
Response Of Photosynthesis In The Leaves Of Cucumber Seedlings To Light Intensity And Co2 Concentration Under Nitrate Stress, Xiaoyu Yang, Xiufeng Wang, Min Wei
Turkish Journal of Botany
The effects of 2 nitrate levels, 14 (CK) and 140 mmol L^{-1} (T), on the leaf gas exchange variables of cucumber (Cucumis sativus L. cv. Xintaimici) seedlings grown in hydroponic culture were investigated. Photosynthetic light- and CO_{2}-response curves from CK and T seedlings were determined and used for the analysis of photosynthetic capacity. The results showed that nitrate stress resulted in a significant reduction of net photosynthesis of T seedlings compared with CK. At the same time, the apparent quantum yield, light-saturated net photosynthesis, carboxylation efficiency, and CO_{2}-saturated net photosynthesis in nitrate-stressed cucumbers also decreased significantly with the increase of …
Comparative Pharmacognostic Studies On The Barks Of Four Ficus Species, K Babu, Gokul Shankar Sabesan, Sadananda Rai
Comparative Pharmacognostic Studies On The Barks Of Four Ficus Species, K Babu, Gokul Shankar Sabesan, Sadananda Rai
Turkish Journal of Botany
The barks of 4 Ficus species, namely F. racemosa, F. virens, F. religiosa and F. benghalensis, are important ingredients in many Ayurvedic and traditional formulations. The barks are considered to be very effective in various treatments, such as diabetes, skin diseases, ulcers, and nervous disorders. During market research, we observed that various species of Ficus barks were sold in Indian market under traditional names, such as Plaksah, Udumbarah, Asvatthah, and Vatah. The barks of the species mention above are usually interchanged or adulterated with other species of Ficus because of the limited knowledge in identification and differentiation. Therefore, a detailed …

Nuclear And Non-Nuclear Interactions In F_1 Hybrid Populations Of Three Solanum Species In The Subgenus Leptostemonum,Section Melongena (Solanaceae), Olatunji A. Oyelana, K. Olusola Ogunwenmo
Turkish Journal of Botany
Reciprocal crosses involving Solanum gilo Raddi, S. anguivi Lam. and S. macrocarpon L., subg. Leptostemonum (Dunal) Bitter sect. Melongena Dunal were produced in order to assess inherent nuclear and non-nuclear influences on hybrid fitness, the extent of genomic change, and species compatibility. Hybrids expressed intermediacy and overlaps in leaf, petiole, petal, and plant height dimensions. Maternal influence was dominant in growth habit, leaf shape and texture, flower colour, and fruit size, while paternal control was limited to fruit colour in Solanum gilo × S. macrocarpon. Pollen viability was reduced from 97.3%-86.5% in parents to 53.8%-20.5% in hybrids. S. gilo × …

Benthic Algae (Except Bacillariophyta) And Their Seasonal Variations In Karagöl Lake (Borçka, Artvin-Turkey), Saadet Kolayli, Bülent Şahi̇n
Turkish Journal of Botany
Seasonal variation in the species composition of the benthic algae of Karagöl Lake was investigated from April to October in 2001 and 2002. The benthic algal flora consisted of 38 taxa belonging to the divisions Chlorophyta, Cyanophyta, Euglenophyta, and Chrysophyta. In general, Chlorophyta were dominant in terms of species number and abundance during the study period. The distribution range of the benthic algae composition and dominant species differed from each other at all stations. Benthic algal growth was mostly influenced by water temperature and light.

Developmental Stages Of Ovule And Megagametophyte In Chenopodium Botrys L. (Chenopodiaceae), Abdolkarim Chehregani, Behrouz Malayeri, Nafiseh Yousefi
Turkish Journal of Botany
The ovule ontogenesis and the megasporogenesis stages in Chenopodium botrys L. were studied with light microscopy. Flowers and young pods were removed from natural plants and fixed in FAA 70, stored in 70% ethanol, embedded in paraffin, and sectioned at 7 µm with a microtome. Staining was carried out with Hematoxylin and Eosin and developmental stages of ovule were studied. The results of this research showed that ovule development, including megasporogenesis and initial stages of megagametogenesis, occurred while flowers were still in bud. In C. botrys the female gametophyte has a monosporic origin and the developmental pattern exhibited by this …

Pollen And Seed Morphology Of The Genus Hesperis L. (Brassicaceae) In Turkey, Münevver Pinar, Ahmet Duran, Tali̇p Çeter, G. Ni̇lhan Tuğ
Turkish Journal of Botany
Pollen and seed morphology were examined in 35 specimens representing 25 Turkish species of the taxonomically complex genus Hesperis L. by light and scanning electron microscopes. Three main types and 2 subtypes were recognized based on the seed coat surface, pollen shape, and exine sculpturing. The seed coat ornamentation of Type I was ocellate, and pollen shape was oblate-spheroidal. While Type II was represented by reticulate seed coat and prolate-spheroidal pollen shape, Type III had tuberculate seed coat. This study revealed that both palynological and seed morphological characters are of significant importance in the taxonomy of the genus.
