(Ankara Univ, Fac Agr, 2016) Tuncer, Burcu; Cig, Arzu; Yanmaz, Ruhsar; Yasar, Fikret
Heat shock treatments are widely used to induce microspore embryogenesis in Brassica species. In this study, the effect of high temperature treatment (32 degrees C and 35 degrees C for 2 days) on microspore embryogenesis was investigated in six genotypes of Turkish white head cabbage (Yalova-1, Ercis, 177 C, 177 T, 531 C, 538 C), three genotypes of Turkish kale (Balkaya, Yanmaz, Karadere 077) and five commercial F-1 ornamental kale hybrids (Red Piegon, Victoria Piegon, Red Chidori, white Kamome, and Pink Kamome). Microspore-derived embryos formation differed depending on genotype and high temperature. The highest embryo yield was obtained as 9.92 embryo per petri dish in cv. Yalova-1, 11.13 embryo per petri dish in Pink Kamome F-1 at 32 degrees C, and 5.63 embryo per petri dish in cv. Karadere 077 at 35 degrees C.

(Academic Journals, 2009) Turkoglu, Nalan; Alp, Sevket; Cig, Arzu
The temperature requirement is important factor for adaptation to an ecology of any plant species. Plant seeds growing in the places with high altitutes are excepted to well develop at lower temperatures. In addition, temperature highly determines when seeds will germinate under field conditions. With different flower colors and appearence, Centaurea is an annual, biennial and perennial plant genus, alternatively used for culture plants in landscape architecture works. Centaurea virgata growing at 1750 altitude were germinated at different temperatures. Their germination rate and their percentage of germination were investigated and the best germination temperature assessed. In this study, seeds from roadsides and fields of Centaurea balsamita, Centaurea iberica and C. virgata growing at 1750 altitute were germinated at different temperatures. Their germination speed and germination percentage were investigated and the best germination temperature was assessed. As a result, the best germination percentage and speed was C. balsamita at 15 degrees C.

(Ankara Univ, Fac Agriculture, 2024) Taskesen, Esra Yildiz; Cig, Arzu; Turkoglu, Nalan
In order to achieve the desired quality characteristics and good growth in ornamental plants, various applications are carried out. Recently, the importance of beneficial bacteria, which play an extremely important role in sustainable ecology and are environmentally friendly, has been increasingly recognized. However, the effect of beneficial bacteria, which are not sufficiently applied in ornamental plants as well as in other plant groups, on the growth and quality characteristics of spray carnation variety, which is the most preferred among cut flowers, was investigated in this study. In the greenhouse, the carnation seedlings were treated with Enterobacter ludwigii (KF29A), Pseudomonas fluorescens (KF31B), Paenarthrobacter nitroguaiacolicus (KF3B), Pseudomonas sp. strain VG242B (KF5A), Paenibacillus xylanilyticus (KF63C), Pseudoalteromonas tetraodonis (TV126C) bacteria which have been selected according to nitrogen fixation, phosphate solubilizing, ACC deaminase and siderophore production properties were applied. In the study, in which phenological and morphological observations were made, the effects of bacterial inoculations were tried to be determined. The effects of beneficial bacteria treatments on the number of petals, the number of nodes, the length between the nodes and the weight of the branches in the carnation plant were statistically insignificant; effects on the parameters of bud first bloom time, full bloom time, time from planting to first harvest, number of flower buds and stem length (P<0.01), flower (diameter) width and stem thickness (P<0.05) was found to be statistically significant. First bud bloom, full bloom and time from planting to first harvest are 103.38 days, 103.74 days and 106.28 days (KF63C) respectively, maximum number of flower buds is 4.77 (TV126C), flower diameter is 46.73 mm at the widest (KF63C), the highest stem thickness was 3.39 cm (KF3B) and the highest stem length was 56.33 cm (TV126C). The first flowering time of the buds appeared with a delay of approximately 10-30 days compared to the control with bacterial applications. It is seen that bacterial applications cause an increase on flower stem thickness, flower stem length, flower bud and petal number.

(Parlar Scientific Publications (p S P), 2019) Bademkiran, Ferhat; Cig, Arzu; Turkoglu, Nalan
Today, an important problem is the conversion of organic wastes into vermicompost and alternative organic fertilizer is obtained which is beneficial to sustain the productivity of the soil. Vermicompost is fertilizer material rich in symbiotic, asymbiotic microorganisms, mycorrhizal fungi and actinomycetes, as well as worm secretions, growth hormones, enzymes, vitamins and amino acids. Vermicompost increases the population of beneficial organism in the soil by using these beneficial properties in plant growth and suppresses diseases and harmful effects and provides positive changes in physical, chemical and biological parameters of soil and provides significant improvements in plant growth and yield and nutrient uptake. This study was conducted in order to examine the effects of solid and liquid earthworm fertilizer dosages on nutrients uptaking of Narcissus cv. 'Royal Connection' plant in the Siirt University in 2016-2017 in the ecological conditions of Siirt province. The 25, 50 and 100 g (S1, S2 and S3) for solid fertilizer and; 0.5%; 1% and 2% (L1, L2 and L3) for liquid fertilizer was applied on each bulb. In the study, some nutrients in leaves and bulbs were analyzed. The mean values of N, P, K, Ca, Mg, Fe, Mn, Zn and Cu contents belong to Narcissus bulbs are varied between 1.633-2.013%, 2.787-4.195%, 0.631-0.795%, 0.366-0.866% (p<0.01), 0.096-0.162% (p<0.05), 179.265-399.063 mg kg(-1) (p<0.01), 14.620-16.674 mg kg(-1); 155.697-461.033 mg kg(-1) (p<0.01), and 30.333-45.799 mg kg(-1), respectively.

(Taylor & Francis Ltd, 2015) Eryigit, Tamer; Cig, Arzu; Okut, Nese; Yildirim, Bunyamin; Ekici, Kamil
This study deals with the chemical composition and antimicrobial activity of essential oils of Vitex agnus castus L. The main constituents of the essential oils were characterized by GC-MS which resulted in the identification of 26 components, representing 100 % of the oil. The dominant compounds in the oil of fruits were trans-caryophyllene (19.17 %), sabinene (18.05 %) and 1,8-cineole (16.13 %), alpha-terpinyl acetate (6.91 %) and dihydroselarene (6.73 %). Antimicrobial activity was tested using the disc diffusion method. According to the inhibition zones, the essential oils were active against all of the tested microorganisms. The essential oils showed the susceptible inhibition zones, but they were less effective against bacterial strains compared to ampicillin and ofloxacin. The organisms most susceptible to these essential oils were Enterococcus faecalis ATCC 29212. However, further studies must be performed to confirm the safety of these oils for use as an antimicrobial agent.

(Hard, 2024) Cig, Arzu; Gulser, Fusun; Gulser, Efdal
In this study, the effect of mycorrhiza (Glomus intraradices N.C. Schenck & G.S. Sm.) inoculation on the micronutrient and macroelement uptakes in different organs of daffodil (Narcissus tazetta L.) grown under saline conditions is examined. For this purpose, Narcissus tazetta plant grown in the climate chamber was treated with sodium chloride (NaCl) at three different concentrations such as salt -free (S0), 34 mmol (S1) and 68 mmol (S2) in mediums with mycorrhiza (M+) and without mycorrhiza (M-). At the end of the experiment, the uptakes of sodium (Na), iron (Fe), manganese (Mn), zinc (Zn) and copper (Cu) uptakes in the bulb, root and leaves of the plant were analyzed. The effects of salt and mycorrhiza interactions on the N uptakes were statistically significant at the 5% level in bulbs. The effects of salt applications were found significant at 1% level for all nutrients uptakes of roots except Cu uptake (5%). The effects of interactions among salt and mycorrhiza were found significant at 5% level for P, Ca and Mn uptakes and at 1% level for Mg, Fe and Cu uptakes of leaves statistically. Increasing doses of sodium chloride had statistically negative effects on nutrient uptakes of different organs except Na and K uptakes of bulbs. Mycorrhiza applications generally increased nutrient uptakes of daffodil's roots and leaves under salinity conditions. The interactions between salt and mycorrhiza were significant for N in bulbs, for N, P and Fe in roots and for P, Ca, Mg, Fe, Mn and Cu in leaves. The decreases in these nutrients uptakes by 68 mmol NaCl applications were lower in mycorrhiza applications than those in non mycorrhiza applications.

(Hard, 2021) Bintas, Pinar Arica; Cig, Arzu; Turkoglu, Nalan
This study was conducted to determine the effect of N:P:K fertilization and some bacterial species on the flowering and development of Hyacinthus orientalis cv. 'Delft Blue' plant. In the study carried out under laboratory conditions according to randomized plot experiment design, full and half (1/2) dose of 20:20:20 N:P:K commercial fertilizer was applied to hyacinth bulbs as inorganic fertilizer. Nitrogen-fixing bacteria: Cellulomonas turbata (TV54A), phosphate solubilizing bacteria: Bacillus-GC Group (TV119E) and nitrogen-fixing and phosphate solubilizing bacteria: Kluyvera cryocrescens (TV113C) and TV54A and TV119E bacteria types were used as biological fertilizers. In the study in which some phenological and morphological observations were made, the earliest time of first flowering, full flowering and harvesting were determined as 52.07, 53.70 and 54.66 days in 1/2 N:P:K application and the difference between the applications was found to be statistically significant (P<0.001). Bacterial applications caused a ten-day delay. The highest leaf width average (24.43 mm) was obtained in TV119E application (P<0.01). The maximum number of leaves was 7.13 (1/2 N:P:K), leaf length was 245.57 mm (TV113C) and plant height was 364.24 mm (TV119E). It was found that bacteria prolong the flowering start times, that is, N:P:K fertilization makes flowers bloom in a shorter time. In addition, leaf growth and bacterial inoculation of the plant were determined to be effective.
