Öğe Impacts Of High Voltage Electric Field (Hvef) Applications On Germination And Seedling Growth Of Seed (Triticum Aestivum L.) With Analysis By Fourier Transform Infrared (Ftir) Spectroscopy(Parlar Scientific Publications (P S P), 2018) Ince-Yilmaz, Ozlem; Erol, Taskin; Kara, Kamil; Dogan, Mustafa; Erdem, UmitWheat is an important widely grown cereal that its grains used worldwide as a staple food. In this study, germination and seedling growth characteristics of grains of Triticum aestivum, the most widely grown species of the genus, in response to HVEF applications were studied. Three different intensities (50, 100 and 200 kV/m) were applied for 1, 5 and 10 min durations. Germination percentages were not affected by treatments, while germination speeds were inhibited by high intensities at long durations. Maximum enhancement in seedling growth measures which were given as root and shoot lengths and dry weights was determined for 5 min 50 kV/m treatment, where increases in average seedling lengths and dry weights were 34.2 % and 26.1 %, respectively. 1 min durations of treatments were also highly improved seedling growth, particularly at root measures. ATR technique was used to analyze the roots and first foliage leafs of treated seeds at FTIR spectroscopy. FTIR results supported that HVEF treatment could be a useful tool for enhancement of wheat seedling growth in early stages of development.Öğe Effects Of Some Botanical Insecticides On The Egg Parasitoid Trichogramma Pintoi Voegele (Hymenoptera: Trichogrammatidae)(Parlar Scientific Publications (P S P), 2016) Tunca, Hilal; Tatlı, Sahin; Moran, H. Hilal; Ozkan, CemEgg parasitoids are among the most significant biological control agents of a number of insect pests. Among them, Trichogramma species are the most widely used insect natural enemy in the world. Generally, when it raised the idea of using biological control, the effects of insecticides should be studied under laboratory conditions before the release of beneficial natural enemies. In this study, effects of some botanical insecticides on development and behaviour of Trichogramma pintoi Voegele (Hymenoptera: Trichogrammatidae) were studied. The experiments were conducted on the host Ephestia kuehniella Zeller (Lepidoptera: Pyralidae), at 25 degrees C, 60-70% relative humidity in the laboratory condition. In the experiments, Neem Azal (azadirachtin) and Spruzit Neu (pyrethrum, hotpepperwax (capsaicin) and Orange Guard (d-Limone) were tested. With the use of LC10, LC25, LC50 ve LC90 doses of Neem Azal and Spruzit Neu against parasitized and unparasitized E. kuehniella eggs, insecticide side effects to the parasitoid biology and behavior was designated. Parasitism rate of T. pintoi was negatively affected by application of azadirachtin and pyrethrum. This negative effect was more observed at pyrethrum. Some biological properties of parasitoid also showed differences depending on parasitoid development stage, insecticide and application dose. Emergence ratio of the parasitoid was significantly affected by LC90 of both insecticide. The results also showed that the most sensitive period of parasitoid was larval stage. In adult toxicity experiment, pyrethrum was found to be more toxic than azadirachtin. The results of behavioral experiments show that these botanical insecticides have strong repellent effect to the parasitoid.Öğe Carolina poplar (Populus x canadensis Moench) as a biomonitor of trace elements in Black sea region of Turkey(Triveni Enterprises, 2010) Celik, Sehnaz; Yucel, Ersin; Celik, Sezgin; Gucel, Salih; Ozturk, MunirIn this study, the leaves, bark and the soil supporting Populus x canadensis Moench were tested as a possible biomonitor of trace element pollution in the Middle Black Sea region of Turkey The investigations were carried out at 23 sites. The leaves, bark and soil were analyzed for Pb++, Cd++, Fe++, Cu++ and Zn++ contents. The values of Pb++, Cd++, Fe++, Cu++ and Zn++ in the leaves varied between 14.5-40.0, 0.5-1.5, 135-486, 5.0-14.0 and 43-246 ppm, respectively. In the bark the values were between 15.5-36.5 (Pb++), 1.5-2.0 (Cd++), 39-575 (Fe++), 5.0-14.0 (Cu++) and 40.0-1468 ppm (Zn++), whereas in the soil values forPb** were 1.0-4.1 ppm, for Cd++ 0.2 ppm, for Fe++ 0.6-1.8 ppm, for Cu++ 0.1-0.9 ppm and for Zn++ 0.1-1.9 ppm. A positive correlation was found between traffic density and the amount of Pb++, Fe++ and Cu++ in leaves, while a negative correlation was documented for Cd++ and Zn++. In the bark samples there was a positive correlation between traffic density and Pb++, and a negative one with Cd++, Fe++, Cu++ and Zn++. Apositive correlation was determined between traffic density and the amount of Pb++, Fe++, Cu++ and Zn++ in soil. However, the amount of Cd++ was 0.2 ppm and no relationship between Cd++ and traffic density was observed.Öğe Canonical correlation analysis for studying the relationship between the basic morphological and some soil chemical characteristics of Centaurea mucronifera DC. (Asteraceae)(Asian Journal Of Chemistry, 2008) Celik, Sezgin; Yuecel, Ersin; Mendes, Mehmet; Tug, G. Nilhan; Oeztuerk, MuenirThis aim of this study was to investigate the relationship between the basic morphological features and some soil chemical characteristics in order to enlighten the differentiation in the Centaurea mucronifera populations distributed at 16 different places under varying environmental conditions. For this purpose method of Canonical correlation analysis (CCA) was used. The results revealed that morphological features like length of terminal leaves (Y3), length of capitula (Y4), length of involucrum (Y5) and length of achen (Y6) are affected positively by N (X6) and Ca2+ (X7) in the soil but the length of plant (Y1), length of basal leaves (Y2) and length of pappus (Y7) are affected negatively.Öğe Morphological variation and plant nutrients effects of two taxonomically distant Centaurea L. species(Asian Journal Of Chemistry, 2008) Celik, Sezgin; Oezkan, Kuersad; Yuecel, ErsinIn this study, the influence of habitat on Centaurea mucronifera and C pyrrohoplephara, whose morphological variants show obvious differences, spreading on calcareous soils of Mediterranean, Central and East Anatolia were examined. C. mucronifera and C pyrrohoplephara are both perennials and have the height between 4 and 50 cm. The influence of nutrition elements in plant and physical and chemical properties of soils on morphological variations of C mucronifera and C. pyrrohoplephara were determined with the models that have the highest explanation portion without multiple linkage problems on the base of model and variant and their relationships were investigated by using Stepwise Regression Analysis. It was found that there was a univariate independent model, showing the positive contribution of phosphorus content of root on plant nutrition element content and root length and for sodium content of stem on length of basal leaf and outer whorl of pappus in C mucronifera. In C pyrrohoplephara, between morphological characteristics and plant nutrition elements, on the base of model and variant, models having highest explanation portion without multiple relation problems were defined for variants of root length, plant length, width of basal leaf, capitula and involucrum, achene length, pappus inner whorl length. There was not any defined model determining the relationships between physical and chemical properties of soils and length and width of terminal leaf(p < 0.05). According to these results, it was found that, for C.mucronifera and C pyrrohoplephera, physical and chemical properties of soils have an important role on the morphological structure of these species and there could be relationships between morphological structures of these taxa and the ratios of the variants of these plant nutrition element contents and also the influence of plant nutrition elements on the morphological differentiations of these species is relatively low (p < 0.05).Öğe Conservation strategy of critical endemic Centaurea hausknetchii Boiss. (Section : Cyanoroides) and effects of different salt, nitrate and acid concentrations on the germination of seeds(Asian Journal Of Chemistry, 2008) Celik, Sezgin; Yucel, ErsinCentaurea hausknetchii is a local endemic species growing only in the Nemrut Mountain Historical National Park in the Southeast Anatolian region of Turkey. It grows in three small areas of this mountain and all these areas are under heavy grazing pressure. The germination behaviour of the seeds was studied and for this purpose seeds were left under two different photoperiods (8 h light-16 h darkness and 16 h light-8 h darkness) and treated with different concentratios of NaCl, KNO(3), H(2)SO(4) and HCl solutions. There was no germination in 3 % NaCl, 1-3 % KNO(3), 1-3 % H(2)SO(4) and 2-3 % HCl concentrations in each photoperiod. According to the univariate variance analysis of germination Lest results, germination media with different salts, nitrate and acid concentration (e.g., 0.5 %,1.0 %, 2.0 % NaCl; 0.5 %.1.0 %.2.0 %,3.0 % KNO(3); 0.5 % H(2)SO(4); 0.5 %, 1.0 % HCl) under different photoperiods (8 h light-16 h darkness and 16 h light-8 h darkness and 24 h light) and control have been investigated. The photoperiod and photo period-treatment interaction had a significant impact on the germination percentage and rate (p < 0.05). C. hausknetchii is in the critically endangered category (CR) in the IUCN 2000 Red Data Book. The habitat characteristics of the distribution sites were thus investigated, vegetative growth behaviour followed and interrelations between the increase and spread of populations recorded. The factors effecting the productivity were determined. This report will be helpful in the population biology studies and development of alternatives for effective protection programme.Öğe Verbascum ozturkii (scrophulariaceae), a new species from East Anatolia, Turkey(Pakistan Botanical Soc, 2008) Veliogullari, Faik Ahmet Kara; Uzunhisarcikli, M.

A great impetus has been given to this during the last 3 decades. Several publications have been made by different investigators. Large number of naturally growing plants are collected and sold at the markets. Nearly 500 plants are used for primary health care in Turkey and a 23 in Cyprus. However, not much is known about the poisonous plants. Some of these are toxic and others cause reaction. Plant poisoning lies around 6%, rurals suffer more from the consumption of naturally growing plants as compared to urban dwellers. One has to be very cautious before using these plants as the plants used for the purpose of treatment of diseases as a whole or parts thereof or consumed by the public directly could prove dangerous for the health. This paper describes ethnoecological aspects of the widely distributed major poisonous plants in Turkey and Northern Cyprus which can prove fatal if used unknowingly. Major applications and active constituents of plant taxa are outlined.
