This paper describes the landscape character analysis method within the Kure Mountains National Park in Turkey. This study assesses structural differences in the distribution of landscape character types in the National Park, buffer zone and their fragment states. It is seen that these differences arise from biotic and abiotic factors but those abiotic factors have a stronger impact on diminishing biological diversity, disintegration and increase of isolation values. Through the basin were identified 345 landscape character types. Despite having similar values, the surface area of the protected area in the national park and the rural area are of significant differences in landscape character ratios and patchiness ratio. Patchiness is seen to be higher in rural areas. When looked at Shannon Diversity Index (SDI) values, it is seen that a high diversity of Landscape Character Types (LCT) exist in the rural area. Landscape diversity is higher in the rural area compared to the Kure Mountains National Park and the areal distribution of landscape character types is more regular. According to the National Park protection and National Park planning area values the patchiness ratio in the planning area as well as the landscape diversity is high and the areal distribution of landscape character types is more irregular.

This study was carried out to define the effect of surface drip irrigation approaches on yield and quality parameters of orange ( Citrus sinensis cv. Valencia Late) trees during the growing periods between 2014-2016 years at the private farm in Guzelyurt, Northern Cyprus. The volume of drip irrigation water applied was based on total Class A pan evaporation (K cp1 :1.25, K cp2 :1.00, K cp3 :0.75 and K cp4 :0.50) and experimental plots were irrigated when the total amount of Class A pan evaporation was about 35 ± 5 mm. It was determined that irrigation treatments affect yield, fruit weight, fruit length, fruit width, juice, total soluble sugar, total acidity, pH and vitamin C content except for peel thickness. The average evapotranspiration values were 1343.5 mm for K cp1 , 1135.0 mm for K cp2 , 956.0 mm for K cp3 , and 787.3 mm for K cp4 irrigation treatments. According to the data of 2 years, yearly yield for K cp1 , K cp2 , K cp3 , and K cp4 irrigation levels were 45.0 t ha -1 , 47.1 t ha -1 , 38.7 t ha -1 , and 19.2 t ha -1 , respectively. It is determined that Valencia late can be irrigated by means of the amount of irrigation equivalent to 75% of Class A Pan in Guzelyurt region in Turkish Republic of Northern Cyprus.

Propolis is a resinous product with a complex structure. The composition of raw propolis depends on many factors such as flora of the area, harvesting season, collection style and bee strain. But with these differences all propolis samples contains flavonoids, aromatic acids, diterpenic acids and phenolic compounds and these components are responsible for its antitumor, anticancer, antiviral and antifungal effects. In this study, effect of season and bee races on propolis composition were investigated. The chemical profile of the propolis was characterised by using HPLC-UV. The amount of total phenolics, total flavonoids, total antioxidant capacity as ferric reducing/antioxidant power (FRAP) and free radical scavenging activity as shown by 2,2-diphenyl-1-picrylhydrazyl (DPPH) were determined. Propolis samples were collected from May to September in Duzce Province, Turkey, from five different honey bee types consisting of three races ( Apis mellifera caucasica, Apis mellifera syriaca, and Apis mellifera carnica ) and two ecotypes (Yigilca and Mugla) indigenous to central Anatolia. The results revealed that the genetic differences of bee colonies and the gathering time affected the phenolic composition and antioxidant properties of the raw propolis. In addition, the study indicated that higher quality propolis could be obtained from bees that live in suitable habitats.

In this paper, the effects on secondary metabolite accumulation of brassinosteroid (BR) (24-epibrassinolide (24-eBL) on immobilized cells that were obtained from Vitis vinifera cv. Cinsault was investigated. 24-eBL was applied to immobilized cells covered calcium alginate beads at concentrations of 0, 0.25, 0.50, 0.75 and 1.0 mg L-1 for one month. As a result of this study, it was found that 24-eBL applications modified secondary metabolite accumulation and had positive effects on secondary metabolite production if the suitable concentration was used. While the highest total phenolic, catechin, chlorogenic acid, and p-coumaric acid contents were found in immobilized cells applied 0.75 mg L-1 24-eBL, the highest epicatechin, quercetin, trans-resveratrol contents were obtained in immobilized cells applied 0.50 mg L-1 24-eBL and the highest gallic acid content was determined in immobilized cells applied 0.25 mg L-1 24-eBL. On the other hand, the highest 24-eBL concentration (1 mg L-1) had decreased the content of secondary metabolite compared to the control (0 mg L-1 24-eBL) except total phenolic and catechin content. To conclude, 0.50 and 0.75 mg L-1 24-eBL concentrations were the most suitable concentrations for immobilized cell culture to provide the highest secondary metabolite accumulation.

The aim of the study is to evaluate effectiveness of a rainwater harvesting technique with polyethylene film covered ridges (RHCR) on pumpkin seed production under rainfed conditions in Kayseri/Turkey. For this purpose, a two-year experiment, of which were consisted three covered ridge widths (R 1 = 0.5, R 2 = 0.7, and R 3 = 0.9 m) and a control treatment, was conducted. The experimental design was completely randomized plots in blocks with three replications. Significantly higher seed yields were obtained from R 2 and R 3 (202 and 208 kg ha -1 ) in first year and from R 2 (660 kg ha -1 ) in second year. Although excessive drought conditions were experienced during pumpkin growing period in those years, especially R 2 treatment resulted significantly higher yield. Higher plant density in R 1 and lower density in R 3 negatively affected seed yield especially in water scarce second year. In second year, leaf area, mean fruit weight, fruit yield, seed yield and 1000-seed weight were found higher than ones in first year because of application of nitrogen a whole at sowing. We concluded that RHCR with optimum plant density and proper covered ridge wide, and application whole nitrogen at sowing under rainfed conditions are effective ways to obtain higher pumpkin production in semiarid regions.

The use of biochar (BC) has an environmental importance in terms of climate change, soil fertility, waste management and energy generation. The purpose of this study was to reveal some of the structural characteristics of BC produced from agricultural wastes by employing spectroscopic techniques within a short time frame. The BCs were produced via slow pyrolysis at 300°C from four feedstocks: tea waste (TW), hazelnut husk (HH), rice husk (RH) and poultry litter (PL). The pH of plant-derived BC was alkaline (pH: 7–9), and the pH of manure-derived BC was strongly alkaline (pH: 10.1). PLBC has the highest (4.67 dS m−1) electrical conductivity (EC) when compared to other BC materials. According to the X-ray fluorescence (XRF) analysis method, organic compound contents of TWBC and HSBC were found to be higher than the other two BCs, while the other two BCs (RHBC and PLBC) were richer in mineral content. TWBC and HHBC were composed of more mineral elements when compared to RHBC and PLBC, but the latter two were still rich in minerals. The surface area of RHBC was found higher (12.9 m2 g-1) than other BC materials. According to the X-ray fluorescence (XRF) analysis method, the total element content of PLBC was found higher than the other BCs. In addition, the silicon (Si) content of RHBC was considerably higher (16.4%). In PLBC’s XRD diagram: quartz (SiO2) at 3.41 (A); calcite (CaCO3) at 3.96, 2.94 and 1.91 (A); sylvine (KCl) at 3.06 and 1.85 (A); and whitlockite ([Ca, Mg]3 [PO4]2) at 2.78 and 2.17 (A) were found. In HHBC and RHBC diagrams, partially crystallized carbon (CryC) peaks were mainly observed between 1.20 and 2.34 (A), and cristobalite peaks (i.e., amorphous SiO2) were observed at 3.91 and 3.40 (A).

Nigella sativa L. is a significant medicinal and aromatic plant due to its using areas of seed and fixed oil. The aim of the study was to investitigate the effects on seed yield, some yield components, fixed and essential oil content, and chemical compositon of black cumin of seed harvest at different stages of maturity. Two-year field experiments (2017 and 2018) were set up according to randomized complete block design with triplicate using a local black cumin variety obtained from Burdur province under Isparta ecological conditions of Turkey. The seed harvest (SH) in black cumin were made to four maturitiy stages. These stages were 25% (SH1), 50% (SH2), 75% (SH3) and 100% (SH4) browning of capsules. Statistically significant differences were found among the harvest stages in point of the seed yield, plant height and thousand-seed weight, while no differences were found in the numbers of capsules and branches, essential oil and fixed oil contents in both experimental years. Seed yield and its components increased during the harvest stage up to SH3, while essential oil and fixed oil contents decreased insignificantly from SH1 to SH4 in both years. According to combined years, plant height, number of capsules, number of branches, 1000 seed weight, seed yields, essential oil and fixed oil contents varied between 38.3-42.5 cm, 6.03-6.85 capsule plant-1, 6.50-6.91 branches plant-1, 2.30-2.57 g, 307.3-542.3 kg ha-1, 0.087-0.101% and 31.14-32.69%, respectively. The main components of black cumin essential oil were characterised by cymol (25.01-26.90%), thymoquinone (2.39-4.41%), carvacrol (10.12-10.41%), junipene (5.33-6.66%), Δ-3-carene (5.55-8.71%), β-pinene (2.98-3.65), trans-sabinene hydrate (8.02-11.93%) and α-thujene (7.82-9.42%) according to harvest stages in 2017 season.

The aim of the study was to investitigate the effects on seed yield, some yield components, fixed and essential oil content, and chemical compositon of black cumin of seed harvest at different stages of maturity. Two-year field experiments (2017 and 2018) were set up according to randomized complete block design with triplicate using a local black cumin variety obtained from Burdur province under Isparta ecological conditions of Turkey. The seed harvest (SH) in black cumin were made to four maturitiy stages. These stages were 25% (SH1), 50% (SH2), 75% (SH3) and 100% (SH4) browning of capsules. Statistically significant differences were found among the harvest stages in point of the seed yield, plant height and thousand-seed weight, while no differences were found in the numbers of capsules and branches, essential oil and fixed oil contents in both experimental years.

Hot water (HW) and modified atmosphere packaging (MAP) treatments were evaluated to maintain postharvest quality of ‘pomegranate fruit cv. Hicaznar. After immediately harvest, pomegranate fruit was subjected to the following treatments: (1) Fruit was dipped in hot water (at 50 °C for 3 min) and stored in plastic boxes (HW); (2) fruit dipped in hot water was packaged with MAP bags (HW+MAP); (3) fruit without hot water dip was packaged in MAP bags (MAP); (4) fruit was dipped into water at 24 °C for 3 min and stored in plastic boxes (W) and (5) Control fruit without HW and MAP treatments was stored in plastic boxes (C). Fruit was then kept at 6 °C for 6 months and at 20 °C for 7 days after cold storage period. MAP and HW+MAP treatments reduced weight loss, fungal decay and husk scald, and maintained husk and aril color and overall visual quality for 6 months of cold storage and the subsequent shelf life period. Although HW treatment reduced weight loss and fungal decay compared to control treatment, was not effective as MAP and HW+MAP treatments to maintain quality parameters.
