Türkiye’deki Zeytin Çeşitlerinin Moleküler Analizlerinin Genel Değerlendirmesi
Olive (Olea europaea L.) is one of the oldest species cultivated in the Mediterranean basin. It has an important place in terms of human health with its fruit, oil and other by-products and it has been serving humanity with its economic importance for thousands of years. Cultured olive belongs to the genus Olea of the family Oleaceae and there are about 90 cultivars in Turkey. Other transitional forms between these varieties and wild olives forms constitute a wide genetic diversity. Interfertile olives and a lot of varieties have high levels of heterozygosity. While this makes it more difficult to verify varieties, the situation becomes more complicated when combined with cross pollinization. The phylogenetic relationships of Turkish varieties and these different forms have not been fully elucidated due to many reasons such as incorrect labeling, synonyms, local naming. Until the 1990s, varieties were identified with their morphological characteristics and separated from each other. This problem has begun to be resolved to some extent with the development of technology and the use of biotechnological methods in agriculture. Many researchers have been conducted in the world and in our country on identify cultivars and determine the relationships between cultivars with molecular markers. However there are some contrasts between the results of studies. The aim of this article is evaluate together the results of previous studies on Turkish varieties and to present the current situation for future studies. © 2019, Centenary University.

A general study of commercial dried fig production in the Big Meander Valley of Turkey
Turkey is the leading country in dried fig production both in terms of quantity and quality. Even so, there are many problems that need to be solved. To identify the main problems present at the farmer's level and to determine the main sources of failure, a survey was conducted in the Big Meander Valley, the main center of dried fig production. A questionnaire in which questions related to orchard establishment, cultural practices, pests and diseases, physiological disorders, harvest, drying and extension work take place was prepared. 112 farmers representing the region were selected and interviewed. The results are statistically analyzed and evaluated in terms of the appearing problems
Investigatións on in vitro rooting and acclimatization of sour cherry cv. heimanns rubinweichsel
Sour cherry shootlets obtained via in vitro propagation were rooted in half concentrated MS medium containing 5.5; 11.0; 16.5 and 22.0 µM IAA, IBA and NAA. It was noticed that they rooted well in those levels, however, with regard root color, shape, thickness and callus production rate, IAA has proven itself better than the others. Perlitte, peat, soil-sand-manure mixture; pomza, while later development of the plantlets were better in peat and sand-manure mixture
In Vitro Propagation of Ficus carica cv. Sarilop Clone Selected for Its High Performance
3rd International Symposium on Fig -- MAY 16-20, 2005 -- Algarve, PORTUGALWOS: 000261594100027'Sarilop' (= Calimyrna) is accepted as a standard fig cultivar for drying due to its high fruit quality all over the world. In Turkish dried rig production that depends fully on cv. Sarilop, the policy is to reduce the percentage of defected fruits rather than extending the acreage. To fulfill this aim, a clonal selection was carried out, and some promising clones were selected in terms of fruit yield and quality. Thereafter, Clone 37 was selected to be the best among the promising clones. On the other hand, all of the cv. Sarilop trees were found to be infected with rig mosaic virus. Thus, propagation of selected clones by apical meristem or shoot tip culture for virus-free and/or mass propagation purposes became a must. This experiment is designed to determine the most suitable conditions and media for propagating cv. Sarilop Clone 37 through tissue culture. Clone 37 displayed a high performance. As the multiplication medium, the Murashige Skoog (MS) medium containing 1 mg/L IBA, 5 mg/L BA, 1 mg/L GA(3) and 89 ml/L PG were the best, whereas, MS medium complemented with 1.2 and 2.5 mu M IBA or NAA were better in respect to rooting. Peat followed by volcanic tuff gave the best performance for acclimatization to outdoor conditions. The survival rates were lower in Perlite and in sand, soil and cow manure mixture (1:1:1).Univ Algarve, Int Soc Hort Sci, Assoc Portuguesa Hort, Int Ctr Adv Mediterranean Agron Studies, DRAPALG, FCT, Caixa Geral Depositos, Camara Municipal Faro, Camara Municipal Tavira, Camara Municipal Loul
Propagation of mahaleb by tissue culture
The aim of this research was to facilitate propagation of some Turkish mahaleb genotypes by in vitro techniques. Shoot tips of annual shoots were used as explants. Murashige and Skoog (MS) medium was supplemented with different plant growth regulators. Shoot length, number of leaves and multiplication rate were recorded every 30 days. In multiplication stages, ten different media were tested. The optimum multiplication medium was obtained on MS medium supplemented with 1 mg L-1BAP + 0.1 mg L-1IBA + 0.17 mg L-1GA3. Shoots rooted in MS medium supplemented with 0.3 mg L-1NAA. Rooted in vitro shoots were transferred into pots filled with peat for acclimatization. © 2020 International Society for Horticultural Science. All rights reserved
