Öğe The determination of Cd and Zn phytoremediation potential of buckwheat (Fagopyrum esculentum)(DESALINATION PUBL, 2018) Kaplan, Nurdan Olguncelik; Akay, AysenCadmium (Cd) which is absorbed and stored by the plants is causing too many metabolic changes of the plants. The biological function of cadmium is not known over the plants. The plant is generally taking in small amounts the Cd, this element is competing with the zinc (Zn). Buckwheat has relatively high biomass productivity, is adapted to many areas of the world, therefore buckwheat is widely used for the phytoremediation process. The aim of this study was to evaluate the phytoremediation capacity of the high-yielding plant buckwheat in soils contaminated with Cd and Zn. The soils were applied to different doses Cd (0-12.5-25-50-100 mg Cd kg(-1) soil) and Zn (0-10-30 mg Zn kg(-1) soil). Buckwheat seeds (Gunes and Aktas cultivars) were sown and grown under greenhouse conditions. After harvest, Cd and Zn concentrations of plant biomass and grain yield (kg d(-1)) and translocation factors for Zn and Cd were determined. Cadmium accumulation in biomass and grain significantly increased in dose-dependent manner. Gunes genotype accumulated higher lead than Aktas genotypes.Öğe EFFECT OF RHIZOBIUM BACTERIA ON NITROGEN FERTILIZER REQUEST OF COMMON VETCH (Vicia sativa L.)(UNIV AGRICULTURAL SCIENCES & VETERINARY MEDICINE BUCHAREST, 2018) Akay, Aysen; Cicek, AliCommon vetch (Vicia sativa L.) is a single-year legume feed plant, grown in plant-animal production systems for grass and grain purposes in many parts of the world, and is widely used in the feeding of farm ani mals. Turkey is the genetic center of common vetch and 59 of the existing species are naturally present in the Turkish vegetation. The aim of this study was to determine the effect of nitrogenous fertilizer on plant and the appropriate dose of nitrogenous fertilizer and to investigate the effect of plant growth, yield, amount of N uptake by the plant, which is Rhizobium bacterial inoculation. Experiment was carried in controlled greenhouse conditions and used Tamkoc 2000 variety of common vetch seeds and applied Rhizobium leguminosarum L. bacterial and 3 doses of nitrogen (0-3-6 kg/da nitrogen) fertilizer. According to the results of the research it was observed that only the difference in the content of N in grain among the examined parameters. This value is 3.89% N in bacteria-overgrown plants and 3.39% N in bacteria-free plants.Öğe Effect of zinc containing fertilizers in organic and inorganic forms on the yield of barley crop and uptake of nutrients(ASIAN JOURNAL OF CHEMISTRY, 2007) Akay, Aysen; Kaya, Mustafa HarmanThis study was conducted to investigate the effect of treatment of the barley crop (Karatay-94) with zinc ontaining fertilizer under field conditions on two locations. The study was designed according to a randomised complete block experimental design in three replicates and at five different sources of zinc (Zn-gluconate, Zn-pyruvate, ZnO, ZnSO4, Zn-EDTA) and were applied on the leaf in three different doses (0-0.75-1.50 kg/da Zn). The highest grain yield in the study was obtained from ZnO, ZnSO4 and Zn-pyruvate applications on both locations. Although significant increases occurred in yield when zinc sources were applied in different doses on the first location (P < 0.05), no statistical differences were observed among zinc sources. On both locations in the study, significant differences were observed in regard to phosphorus and zinc contents of the flag leaf, zinc content in the grain and zinc. taken up by the grain. Since no statistical differences were observed among zinc sources on both locations (P < 0.0-5), a dose of 0.75 kg Zn/da of ZnSO4 can be recommended due to its economic ciiteria.Öğe Effect of zinc fertilizer applications on yield and element contents of some registered chickpeas varieties(ACADEMIC JOURNALS, 2011) Akay, AysenIn this study, the effect of zinc fertilizer applications on different chickpea varieties and the most suitable zinc application dose were investigated under the field conditions in May to September of 2003 and 2004. Three types of chickpeas (Cicer arietinum cv. Canitez-87, cv. ILC-482 and cv. Gokce) were studied under irrigated conditions. Zinc was applied to the soil at four doses 0, 0.5, 1.0 and 1.5 kg da(-1) before sowing. During the experiment, leaf samples were regularly collected every week to determine the chlorophyll content of fresh leaf tissue. The changes in the total chlorophyll content were followed. Chickpea samples of each variety were harvested mainly taking into account maturation periods. Leaf chlorophyll concentration, grain phytic acid, zinc, nitrogen and phosphorus contents were determined in chickpea varieties. According to the results of the statistical analysis, the chlorophyll content in the leaves showed a significant difference among the varieties for both years (P < 0.01). The values of P, phytic acid and Zn contents in the seed and the Zn content in the leaf of ILC-482 variety were found to be higher when compared with other varieties. According to correlation test results, there were significant (P < 0.05) differences among the described criteria. Significant correlations were observed between phosphorus content in seed and grain yield (r= 0.75(star)); total chlorophyll content of leaves and grain yield (r= 0.78(star)); total chlorophyll content of leaves and phytic acid (r = 0.93(star star)); total chlorophyll content of leaves and phosphorus content in seed (r= 0.72(star)) particularly in ILC -482 variety. The application of zinc fertilizer did not provide a significant increase in the yield. However, significant increases were observed in phosphorus, phytic acid and zinc content in the seed and the chlorophyll concentration in the leaf through zinc fertilizer application at a dose of 1.0 kg da(-1) (P < 0.01).Öğe EFFECTS OF DIFFERENT TYPES OF MYCORRHIZA ON THE DEVELOPMENT AND THE ELEMENTAL CONTENT OF LUPIN (LUPINUS ALBUS L.)(POLISH SOCIETY MAGNESIUM RESEARCH, 2016) Akay, Aysen; Yorgancilar, Mustafa; Atalay, EmineThe effects of different types of arbuscular mycorrhizal (AM) fungi on the root inoculation and plant elemental content of lupin (Lupinus albus L.) were investigated in the present study. The growth and development of lupin were examined to determine the species of AM fungi that can help to grow lupin with a high protein content and economic value. In this study, which was carried out as a pot experiment under controlled greenhouse conditions, first the pots were inoculated with Glomus geosporum, Glomus mosseae, Glomus caledonium, Glomus etunicatium mycorrhizal spores and then lupin (Lupinus albus) seeds were sown. The plants were watered with pure water during the experiment. The trial was terminated after a 60-day plant gowing period. In the study, inoculation occurred at lupin roots at rates varying between 13.3 and 30.0%. However, there was no statistically significant difference among the types of arbuscular mycorrhizal fungi applied to the plant in the inoculation rate. The examination of the effect of the application of different AM (Glomus geosporum, Glomus mosseae, Glomus caledonium, Glomus etunicatium) spore on the plant development showed that AM inoculation did not have an effect on the lupin development. The effect of AM inoculation on the plant's nutrient content revealed no significant difference in the content of crude protein, P and K, while demonstrating a significant increase in the sulphur and magnesium content versus the control. The plant content of crude protein varied between 185.6 and 226.5 (g kg(-1)), phosphorus 0.61-0.74 (g kg(-1)) and potassium - 9.6-11.1 (g kg(-1)). The concentrations of Zn, Cu, B and Mo in lupin did not show statistically significant modifications caused by the inoculation of different types of AM. However, the plant Mn content showed a decrease due to AM inoculation, whereas a significant increase was observed in the Na content after AM inoculation. AM fungi were observed in plant roots after the inoculation with any of the four different types of mycorrhiza. But no positive effects of mycorrhizal inoculation were not observed on crude protein and the uptake of plant nutrients.Öğe Interaction between cadmium and zinc in barley (Hordeum vulgare L.) grown under field conditions(BANGLADESH BOTANICAL SOC, 2007) Akay, Aysen; Koleli, NurcanThe interaction between cadmium (0, 1, 2, 4 and 6 kg/da) and zinc (0, 1.5 and 3 kg/da) in barley (Hordium vulgare L. cv. Karatay-94) alone and in combination at tillering stage (3 - 4 leaf) grown under field conditions showed no phytotoxic symptoms. Cd application did not affect the grain yield of barley. Cd concentrations in flag leaf and grain increased marginally with increasing level of Cd but decreased with increasing Zn application. Cd and Zn application caused insignificant changes in N and K concentrations in barley. But P concentration in grain at especially Zn-0 dose decreased with increasing level of Cd application. The effect of different doses of Cd and Zn on grains Cd content was found to be significant. Increased Cd doses generally decreased Zn content in grains.Öğe Interaction between cadmium and zinc in triticale (X Triticosecale wittmack) grown under field conditions(ASIAN JOURNAL OF CHEMISTRY, 2007) Akay, AysenAn investigation of the interaction between cadmium (Cd) and zinc (Zn) in triticale, a field experiment was conducted. Cadmium and zinc at tillering stage (3-4 leaf) applied by foliar application (individually and jointly) to triticale in the following doses (in kg/da): Cd-0, 1,2,4 and 6, Zn-0, 1.5 and 3. Flag leaf samples were taken at heading stage, and grain samples were also taken after harvest. The concentration of Cd and Zn in flag leaves and grain was measured by ICP-AES. No phytotoxic symptoms were observed during experiment. The grain yield was used as a parameter of growth and Cd and Zn application did not affected the grain yield of triticale. Cadmium concentrations in flag leaf and grain increased with increasing Cd application but decreased with increasing Zn application. Cd and Zn application unchanged nitrogen and potassium concentration in triticale. The effect of different doses of Cd and Zn application on grain Cd content was found statistically significant. Increased Cd doses decreased Zn content in grain.Öğe A New Approach to Fire Blight Control: Mycorrhiza(Amer Soc Horticultural Science, 2006) Bastas, Kubilay Kurtulus; Akay, Aysen; Maden, SalihThe first outbreak of fire blight incited by Erwinia amylovora (Burr.) Winslow et al. occurred on pome fruits in Turkey in 1985, and it is now one of the most serious diseases of pear, apple, quince, and loquat (Oktem and Benlioglu, 1988). In this study, experiments were conducted in Konya Province to evaluate the efficacy of Glomus intraradices Schenck & Smith vesicular-arbuscular mycorrhiza (VAM) and bactericides for control of the shoot blight phase of fire blight and control of shoot growth on the different apple cultivars (Gala, Red Elstar, Pinova, Jonagored) on M9 rootstock in 2002 to 2003. Streptomycin provided 84.38% to 95.24% and 85.28% to 89.97% disease control in 2002 and 2003, respectively. Copper complex was not so effective against shoot blight phase of the disease, and it reduced disease by 16.18% to 27.75% and 14.48% to 19.06% in 2002 and 2003, respectively. Results of VAM application were encouraging, indicating a reduction of fire blight by Glomus intraradices of between 9.7% and 50.5% in 2002 and between 23.9% and 48.4% in 2003, respectively.
