Globe artichoke (Cynara scolymus L.), an herbaceous perennial plant native to the Mediterranean Basin, is cultivated in more than 25 countries worldwide. In Turkey, artichokes are usually planted by transplanting suckers or buds. In commercial plantings, wilting symptoms on 1-year-old plants were observed in September 2014 on 3.0 ha of globe artichoke in Kocayatak district of Antalya Province; in total, the artichoke growing area in Antalya Province covers 144.8 ha (Turkish Statistical Institute 2015). Symptoms began as mild to moderate wilting of the seedlings and chlorosis of lower leaves, followed by collapse of stems and rotting of crowns. Mycelial growth and brown sclerotia were mostly seen at the base of the stem. Of the entire planting, 15 to 20% showed symptoms and died. Infected stem tissue was disinfested for 2 min in 2% NaOCl and plated on potato dextrose agar (PDA) amended with 25 mg streptomycin sulfate/liter. After 5 days growth at 25°C, white hyphae formed clamp connections; after 3 to 8 days of growth, numerous globoid sclerotia 0.5 to 2 mm in diameter appeared. The sclerotia were initially white, gradually turning brown and dark brown-black with age. Based on fungal morphology, white mycelium, sclerotia, and the presence of clamp connections at hyphal septa, the fungus was identified as Sclerotium rolfsii (Mordue 1974; Mullen 2001). Morphological identification was confirmed by ITS sequences of rDNA. After DNA extraction of the isolate, the ribosomal DNA fragment was amplified with ITS1 and ITS4 primers was sequenced (White et al. 1990). Nucleotide sequences of the isolate (GenBank accession no. KU521347) showed a 97 to 98% homology with other S. rolfsii isolates in GenBank (e.g., KT337418, KT337426). To fulfill Koch’s postulates, 8-week-old artichoke seedlings were transplanted into 15-cm diameter pots with autoclaved soil and vermiculite (1:1) in a greenhouse. Mycelial plugs (0.5-cm diameter) of one isolate of the fungus were transferred in a 100-ml beaker containing autoclaved and moistened chickpea seeds. Seven days later, all of the chickpeas were colonized by the fungus. One infected chickpea seed per plant was placed next to the crowns of eight artichoke seedlings and covered with sterile moistened cotton immediately after inoculation to facilitate infection. The same treatment was performed for eight control seedlings with fungus-free seeds. The temperature in the greenhouse was 25°C. After 5 days, inoculated plants began to wilt. Ten days later, white mycelium and abundant sclerotia were found at the base of the seedlings and the plants died. Inoculated plants showed symptoms identical to those observed in the field. Controls remained healthy. S. rolfsii was reisolated from all necrotic crown and stem tissues. To our knowledge, this is the first report of S. rolfsii causing crown rot on globe artichoke in Turkey. © 2016, American Phytopathological Society. All rights reserved.

A total of 95 samples of Meloidogyne incognita (60), Meloidogyne javanica (28) and Meloidogyne arenaria (7) collected from West Mediterranean region of Turkey were tested for identifying races of the nematodes using the North Carolina Differential Host Test. Races 2 and 6 of M. incognita were identified in 58 and 2 samples, respectively. Race 1 of M. javanica was identified from all 28 samples. Races 2 and 3 of M. arenaria were identified in 5 and 2 samples, respectively. The results also showed that two races of M. incognita and all races of M. javanica did not attack on pepper cv. California Wonder. These findings may contribute to improving resistant varieties and may also provide basis for developing a cropping system to control root-knot nematodes. © 2010 Elsevier Ltd.

In this study Antalya, Denizli, Isparta, Karaman, Konya and Nigde province’ farms which are dominant in apple cultivation has been compared in terms of early warning adoption level and some social economic indicators. With this scope in the study region stratified sampling method had been used and sampling size has been determined 267 farms. In these regions early warning system has been used since the late 80’s for black spot and codling moth. Especially after 2000’s successful results of the system provide that a positive effect of the farmers’ adoption level. According to the study results there is a high adoption level of farmers on apple cultivation from early warning system thus 41.6% of the farmers exactly adapt the pesticide application time from early warning system but farmers have lack of information about the system. There is a positive relation between adoption and education level, both levels increase at the same time.Early warning adoption levels also decrease unit production cost of apple. Relative profit has a statistically meaningful relation between early warning adoption level (p<0.05). Total pesticide cost increased 10.92% due to unnecessary usage. Many small farms in these regions can increase their income and provide market advantages with some amelioration in the early warning system, enlargement of practise areas. © 2014, Universidade Federal Rural de Pernambuco.

Turkey’s cherry production was 417905 tonnes, export quantity was 65294 tonnes in 2010 and this has provided $147828000 income to Turkish economy. Turkey is the most important cherry producer with the share of 20.24% of world cherry production. This study has aimed to evaluate Turkey cherry trade development, identify problems, marketing structure and suggest some solutions in cherry production between the years 1990- 2010. In this study has benefited from secondary data sources such as Turkish Statistical Institute and FAO (Food and Agriculture Organization) and also similar publications related to subject. In this study Turkey’s cherry production has been analyzed by 10 phone interviews which were conducted with cherry exporters. Respondents were asked four questions relating to the SWOT of cherry sector of Turkey and also their problems. Responses collected were transcribed and analyzed using a content analysis. © 2016, Universidade Federal Rural de Pernambuco. All rights reserved.

Huitlacoche is the Aztecs name given to the smut galls on ears of maize caused by the pathogenic plant fungus Ustilago maydis [(DC) Corda.)]. It is known as maize mushroom, and it has been considered a delicacy and in Mesoamerica. The aim of the present study was to determine the responses of some maize varieties to the growth of the fungus in order to evaluate the prospect production of these smutty ears as a maize mushroom. A 2-year study was conducted in the Mediterranean region of Turkey in 2010 and 2011. Inoculations were performed by injecting inoculum into the ear through the silk channel of plants in plots. Each treatment had control plots. Average ear-gall (huitlacoche) severity and incidence of all the varieties were at the rates of 4.0 and 41.6%, respectively. However, the highest severity of ear-gall (6.5) and incidence (60.6%) were found in Karadeniz Yıldızı flint maize variety; colossal smutty ears were formed in the maize cultivars. This study showed that certain maize cultivars (flint corn and dent corn) can be used efficiently in the production of huitlacoche. © 2015, Sociedade Brasileira de Ciencia e Tecnologia de Alimentos, SBCTA.

The global climate change, a developing environmental consciousneß and changing consumer trends together with high adopted xeriscape approach in landscaping lead to an increasing use of native plants worldwide. Turkey has very rich plant genetic resources, some of these have potential as ornamental plant for landscape use. Their domestication is especially important for the aßeßment and exploitation of the underused genetic resources. This study was conducted in Bat Akdeniz Agricultural Research Institute in Antalya, Turkey. We aimed to propagate vegetatively 22 native plant species including herbaceous plants, climbers, shrubs and trees. Some of the species are endemic. Mainly adventitious rooting via stem cuttings was used for the propagation of the different species: Acer sempervirens, Amelanchier parviflora, Ampelopsis orientale, Arbutus andrachne, Cionura erecta, Clematis cirrhosa, C. vitalba, Daphne sericea, D. oleoides, Erica bocquetii, E. manipuliflora, E. sicula subsp. libanotica, Melißa officinalis, Myrtus communis, Ostrya carpinifolia, Pistacia terebinthus, Pyrus serikensis, Sedum sediforme, Sorbus umbellata var. umbellata, Tamarix tetrandra and Vitex agnus-castus. Additionally, stock division (for Carex pendula) and radial layering (for A. orientale and C. cirrhosa) were applied. The stem cuttings were inserted in perlite, peat, peat:perlite (1:1), sand, sand:peat:perlite (1:1:1) or cocopite:sand (5:1) mixtures and mostly commercial powdered rooting hormone was applied. Fifteen of the 22 plant species were succeßfully rooted with a ratio ranging from 5 to 100%. The cuttings of A. orientale, C. erecta, C. cirrhosa, M. officinalis and S. sediforme were rooted for 100%. C. pendula was very regenerative for producing sister plants. Propagation results of this initial work were found very promising for the cultivation and domestication of most of the targeted plant species. It might be poßible to increase the propagation ratios by using different substrates and hormone applications especially for difficult to propagate species.

The carmine spider mite, Tetranychus cinnabarinus, and the silverleaf whitefly, Bemisia tabaci, are serious pests of both field- and greenhouse-grown crops in south-western Turkey. Control of these pests has been heavily dependent upon chemical pesticides. The objectives of this study were to investigate the occurrence of indigenous entomopathogenic fungi (EPF) in field populations of T. cinnabarinus and B. tabaci, and to evaluate their pathogenicity against these pests. For this purpose, a survey of EPF isolated from field-collected samples of both pests was carried out in Antalya in 2010 and 2011 using the dilution plating method.Four indigenous Beauveria bassiana isolates (TUR1-B, TUR2-B, FIN1-B, FIN2-B) were recovered. In pathogenicity bioassays with T. cinnabarinus and B. tabaci biotype B, all the isolates tested were pathogenic to some of the biological stages of both pests to varying degrees. FIN1-B and TUR1-B caused mortalities of up to 50 and 45%, respectively, in adults of T. cinnabarinus, and of over 79 and 37%, respectively, in pupae of B. tabaci with 10Overall results suggest that isolates FIN1-B and TUR1-B have potential for management of T. cinnabarinus and B. tabaci. 2016 Society of Chemical Industry.
