Ensuring the olive oil quality and authenticity has become a great importance for both traditional and emerging olive oil producing countries. The chemical composition in olive oil heavily varies depending on the olive cultivar and its growing region, the agronomic applications, the olive oil production methods and the process and storage conditions. With the help of some analytical techniques and data evaluation methods, it is possible to grade olive oils in terms of their differences. This research examines particularly fatty acid composition of commercial olive oils (2017/2018 season) with mass detector coupled with gas chromatography (GC/MS). Results were evaluated for grading of them according to IOC regulations based on cultivar (ripe or unripe Ayvalik and Memecik), production (organic, stone mill, cold press, two or more centrifugation systems, filtered or unfiltered) and packing type (transparent or dark glass bottle and plastic bottle), and also their geographic origin (Ayvalik and Edremit towns, the Cunda Island, North Aegean region or South Aegean Region). According to overall data processing, virgin olive samples could be successfully distinguished in terms of theirs geographic origin and cultivar roots. Moreover, it was also explained that the effect of process and package type for grading of olive oils as ‘extra virgin’ or ‘virgin’.

This research was carried out in the greenhouses of Pamukkale University Menderes Basin Agricultural Application and Research Centre in order to determine the effects of different blossom pruning on yield and quality in Ayza F1 tomato cultivars. The experiment consisted three different applications; pruning group having 6 fruits in flower bunch, pruning group having 7 fruits in flower bunch and control group without pruning. As the quality criterion in the tomato cultivar, total amount of water soluble dry matter (TWSDM %), pH, titratable acidity (TA mval 100 ml-1), hardness of fruit flesh (Newton) and antioxidant content (%) were determined. In addition, fruit diameter (cm), fruit length (mm) and weight (g) were detected. Yield parameters such as total yield (g plant-1), marketable yield (g plant-1), number of fruits (number plant-1), average fruit weight (g fruit-1) were considered detailed. Flower pruning having 6 fruits was prominent in terms of marketable yield, fruit weight, fruit diameter, fruit length and dry matter (DM) values. The effects of the applications on the quality characteristics such as fruit index, TWSDM and pH were found to be insignificant and their effects on DM, TA, fruit flesh hardness and antioxidant amount were detected to be significant.

During the growing seasons between 2009 and 2010, totally 213 shoot and leaf samples were collected from the vineyards in Manisa, Denizli, Nevşehir, Elazığ, İzmir, Ankara, Çanakkale, Tekirdağ, Edirne and Kırklareli, which are commercially important viticulture production areas of Turkey. All grapevine samples were serologically investigated for the presence of Grapevine leafroll-associated viruses (GLRaVs) using GLRaV-1, GLRaV-2, GLRaV-3, GLRaV 4-9, GLRaV-6 and GLRaV-7 DAS-ELISA kits. In 143 of total, (67.14%) single or multiple infections were detected. GLRaV4-9, -7, -3, -1, -2 and -6 were detected as 53.52%, 36.15%, 34.74%, 32. 86%, 32.39% and 3.28%, respectively in the surveyed area. Eastern Anatolia Region had the highest infection rate (100%), followed by Marmara, Aegean, and Central Anatolia Region (69.74%, 75%, 62% and 26.47%, respectively). While the highest infection rates were obtained in Marmara Region for GLRaV-1, -2 and -3 as 43.42%, 44.74% and 50% respectively, GLRaV4-9 found as 100% in Eastern Anatolia Region. The highest infection rate was detected in Marmara Region for GLRaV-6 as 3.95%. The most common multiple infection was determined as GLRaV-1, -2, -3, 4-9 and -7 with the rate of 36.17%.

Intensive pesticide use in vineyard resulted in residue problem on vine leaves that are used as food. This study was aimed at development of a proper chemical control program to reduce the pesticide residue problem on vine (cv. Narince) leaves in vineyards during the growing period. The residues of some fungicides were determined according to spraying time in the fresh (unprocessed) and preserved (brined) leaves. Additionally, the effects of preservation process on degradation of the fungucides residues were investigated. In this study three fungicides (Azoxystrobin, Triadimenol, Hexaconazole) were applied alternately for both powdery mildew and “Colomerus vitis” management, and two fungucides (Copper oxychloride, Metalaxyl + Mancozeb) for downy mildew control. Additionaly vine leaves were harvested at two different times: (i) before the half-life of the pesticides were reached and (ii) after the half-life of the pesticides have elapsed. Two different methods were applied to preserve the vine leaves. In first treatment, leaf samples were boiled in hot (98±2°C) tap water, then leaves were placed into jars, then filled with brine containing 8.0% salt + 0.25% lactic acid. In second treatment, vine leaves were placed into jars, then filled with tap water and brine containing 8.0% salt+0.25% lactic acid. The residue levels of the fungicides were determined on leaves. Detectable copper and the other fungucide residues are compared according to Turkish Food Codex. Preserving applications were decreased fungicide and copper residue levels and hot water brining was decreased the levels of fungicide residues between 75.2% and 99.2%, according to the applications. As a result, systemic fungicides should not be used in vineyards in where pickled vine leaves are produced. It is proposed that better to use contact fungicides instead of systemic one and also viticulturists should be careful using the effective contact fungicides.

In Turkey, the Rosary (Neem) tree, known as the Melia azedarach L. is a type of evergreen plant. In the world, four different species of tree grows native in India, Burma, Pakistan, South Asia, and Australia. In our country, the Neem tree (Melia azedarach L.) grows naturally in tropical zones with light yellow fruit and green leaves. Fruits can reach maturity in September-October morphologically. Neem oil from fruits and powder from fruits and leaves are the main products which are traded in abroad as organic substances. In this study, neem fruit was investigated to obtain the neem oil from Melia azedarach L. in details such as moisture content (MC), drying rate (DR), moisture ratio (MR), Azadirachtin amount (AZ) and macro and microelement parameters. The fruits were collected from locally Turkey and de moisturized in the greenhouse for one week than dried in Infrared cabinet dryer to obtain the neem oil. The Azadirachtin amount results were found 46.1; 45.4; 48.4 (mg/g) through three replications.

Phenolic compounds, organic acids and microbial metabolites as well as high acid content are the main reasons behind the antimicrobial activity of vinegar against various microorganisms. The antimicrobial effect of the vinegar may change depending on raw material, production method and treatment time of the vinegar. In literature, antimicrobial effects of traditionally produced vinegars from different sources such as berry, wood, grape, apple, pomegranate, honey, blueberry, rice and industrially produced vinegars investigated. As a result, vinegars have antimicrobial effect on various gram negative and gram positive microorganisms. The aim of this review is to provide a detailed up-to-date information on the antimicrobial effect of vinegar.

Gladiolus is a perennial geophyte, semi-rustice herb and belongs to the Iridaceae family. Gladiolus is an important bulbous ornamental plant. It is used as cut flowers, garden and potted plants. Turkey, which is among the major gene centers of the world and has a special place in plant genetic diversity, has rich genetic resources of geophytes including Gladiolus. However, many plant genetic resources, including Gladiolus are under genetic erosion because of the environmental and other problems and therefore face with the danger of extinction. Turkey has one Gladiolus species in IUCN Red List category. This species is Gladiolus italicus and its Red list category is Least Concern (LC). Gladiolus italicus is distributed in Macaronesia, Mediterranean basin to central Asia. Also introduced and naturalized in California. It naturally grows in many parts of Turkey. The other Gladiolus species that are reported to be under threat in Turkey are; Gladiolus anatolicus, Gladiolus antakiensis, Gladiolus halophilus, Gladiolus humilis, Gladiolus micranthus. In addition to their potential usage as ornamental plants, their usage in phytomedicine due to the medical properties of the modified stems, leaves and in other related industries increases their importance. Therefore, it is very important to protect these genetic resources of Gladiolus.

This study aims to determine various relationships between liver, gonad and body weights of the two pipefish species caught in two breeding seasons from the Bafa Lake (Muğla) coasts between 2014 -2016. Using beach seine-net in the lake, a total of 208 pipefish specimens (79 Synathus abaster and 129 Synathus acus) were sampled. L-W relationship and Fulton condition factor were W = 2E - 0.94.01, 0.035 ± 0.009 in S.abaster specimens. Also LW relationships and condition factor were W = 8E-0.93.83 , 0.033 ± 0.01 in S. acus. On the other hand mean ± SD of HSI and GSI values were 2.18 ± 1.65 and 7.69 ± 7.12 respectively. In S.acus values 3.22 ± 3.13 and 5.49 ± 5.12 as well. The decrease in HIS and K values, provides sufficient information to claim that species in the lake spend all energy requirement obtained with proper feeding to growth and gonad development.
