Öğe Effects of Nickel Contamination on Nutrient Contents of Daffodil (Narcissus poeticus L. c.v. Ice Folies)(International Journal of Seconder Metabolite, 2017) Cig, Arzu; Gülser, Füsun; Gokkaya, Tuğba Hasibe; Basdogan, GulcinayThe objective of this study was to determine the effects of nickel on nutrient contents of daffodil (Narcissus poeticus L. c.v. “Ice Folies”) in nickel contaminated media. This research was carried out in a completely randomized experimental design with three replications in greenhouse conditions. Four different doses of nickel (control, 25 mg kg-1, 50 mg kg-1, 75 mg kg-1) were applied to each pot having 500 g soil:sand mixture in 2:1 ratio. The distillate water was used in irrigation and ½ hoagland solution was applied for fertilization. At the end of experiment the highest K, Mg and Ca contents of daffodil bulbs were obtained as 0.90 %, 0.91 % and 2.72 % in control respectively. The highest Fe (27.42 mg kg-1), Cu (7.62 mg kg-1), and Zn (20.99 mg kg-1) were in 50 mg kg-1, 75 mg kg-1 and 25 mg kg-1 nickel applications respectively. Similarly the highest K, Mg and Ca contents of daffodil leaves were obtained as 2.2 %, 1.72 % and 5.87 % in control. The highest Fe contents (66.62 mg kg-1) was in 25 mg kg-1 nickel application, while Cu (41.29 mg kg-1) and Zn contents (41.04 mg kg-1) were in 75 mg kg-1 nickel application. Nickel applications increased micronutrients contents of daffodils except manganese.Öğe In vitro Propagation Techniques for Some Geophyte Ornamental Plants with High Economic Value(International Journal of Seconder Metabolite, 2015) Cig, Arzu; Basdogan, GulcinayPropagation of some ornamental plants has increased tremendously due to the demand for them as cut flowers, in addition to their usage for interior and exterior landscaping purposes. Geophytes (bulbous-tuberous) are the most preferred group among the ornamental plants due to their aesthetic features, suitability to be cut flowers and their fragrance. These plants are highly propagated and consumed. The geophyte species which are highly profitable globally traded and constituting 90% of the flower bulb market are Tulipa (tulip), Lilium (lily), Narcissus (daffodil), Gladiolus (gladioli), Iris (iris) and Hyacinthus (hyacinth). In vitro propagation techniques, which provide disease-free mass production options, have started to be used increasingly to fulfil the demand for these species in the market. In this study, the results of in vitro propagation studies for some economically valuable tulip, lily, daffodil, gladiolus, iris and hyacinth species are provided.Öğe Landscape protection in less developed regions, case on wetlands in Van Province, Turkey(Journal of International Scientific Publications: Ecology & Safety, 2013) Baylan, Emel; Basdogan, Gulcinay; Cıg, Arzu…
