Streptomyces bio-products against apple and pear diseases in organic orchards

Tinatin DOOLOTKELDİEVA

Erwinia amylovora as a fire blight pathogen and Venturia inaequalis as a scab pathogen were isolated from the blossoms, exudates, infected fruits, leaves and bent branches of diseased apple, pear and hawthorn trees, selected in the Chy, Osh and Jalal Abad regions. Biochemical and pathogenicity tests, alongside PCR analyses were conducted to identify the local isolates of Erwinia amylovora and Venturia inaequalis. The alternative antagonistic microorganisms which combat bacterium E. amylovora and fungus Venturia inaequalis were tested within in vitro and in vivo conditions. The results revealed ...Более

Microbial communities in pesticide-contaminated soils in Kyrgyzstan and bioremediation possibilities

Tinatin DOOLOTKELDİEVA | Mahabat KONURBAYEVA | Saykal BOBUŞOVA

In Kyrgyzstan, many former storehouses and dump sites for obsolete pesticides exist. In 2009/2010, an inventory and assessment of these sites including risks of environmental hazard has been conducted by FAO and the World Bank. Monitoring revealed high concentration of pesticides listed as persistent organic pollutants (POPs). The purpose of this research was to study the microbial structural complexes of the pesticide-contaminated soils in these dumping zones, and to search for and select microorganism’s destructors with cytochrome P450 genes for pesticide degradation. Culture-dependent and c ...Более

Agro-morphological traits of Cicer reticulatum Ladizinsky in comparison to C. echinospermum P.H. Davis in terms of potential to improve cultivated chickpea (C. arietinum L.)

Mirlan TALİP

Germplasm collections of C. reticulatum and C. echinospermum are limited, while both species face threats from over-grazing and habitat change in their natural environments. Recently many new accessions of C. reticulatum and C. echinospermum were collected in east and south-east Anatolia (Turkey) but they have not yet been evaluated for agro-morphological traits. Therefore, the current study investigated agro-morphological traits of new germplasm sources of C. reticulatum and C. echinospermum and evaluated resistance to biotic and abiotic stresses for chickpea improvement. The most attractive ...Более

A Research on the Determination of Molecular Genetic Characteristics of Some Bemisia Tabaci (genn.) (hemiptera:aleyrodidae) Populations

Hüseyin GÖÇMEN

The whitefly Bemisia tabaci (Gennadius) (Hemiptera, Aleyrodidae) is one of the most crucial agricultural pests in tropical and subtropical regions. The pest is a species complex which contain morphologically indistinguishable biotypes or genetic groups. The aim of the present study is to examine B. tabaci populations collected from Aydin, Antalya, Mersin, Adana and Hatay regions in 2004 and 2005. Prior to analysis, as the first step, the biotypes were determined by considering molecular differences among populations. In addition, the differences among populations were determined by means of bi ...Более

Создание межвидовых гибридов для селекции зерновых колосовых культур на засухоустойчивость

Mustafa PAKSOY

Статья посвящена проблеме продовольственной безопасности. В условиях Кыргызстана зерновые культуры выращивают в разных почвенно-климатических зонах, как на орошаемых, так и на богарных землях, расположенных на высоте от 500до 2000 м, где общая сумма осадков составляет 200-800 мм в год. В связи с этим необходимо создание засухо-, жаростойких, высокопродуктивных и с высокими хозяйственно ценными свойствами сортов зерновых. Для этого нужен разнообразный генофонд, который служит исходным материалом в создании таких сортов. В этой связи нами были использованы разнообразные генетические ресурсы как ...Более

Effects of Some Indigenous Plant Extracts on Meloidogyne javanica Infesting Eggplant and Pepper under Greenhouse Condition

İlker KEPENEKÇİ

Among the major pests of vegetables are Root-Knot Nematodes (Meloidogyne spp.) (RKNs), which cause loss of production due to galling and reduction in root development and shoot growth. Herein, the efficacy of plant extracts of Capsicum frutescens, Hyoscyamus niger, Melia azedarach, Xanthium strumarium and Achillea wilhelmsii were evaluated at 3 concentrations (3, 6, and 12%) against Meloidogyne javanica on pepper and eggplant. Experiments were carried in pots under greenhouse condition, using pepper cv. Charleston and eggplant cv. Kemer as assay plants that are commonly cultivated in Turkey. A ...Более

Bazı Çekirdek Kabağı (Cucurbita pepo L.) Islah Hatlarının Bafra Koşullarındaki Performansları

Mustafa PAKSOY

Çalışmada seleksiyon ıslahı ile geliştirilen on sekiz adet çekirdek kabağı hattının bazı tohum özellikleri ile tohum verimi kriterleri 2 yıl süreyle incelenmiştir. Tohum boyu (18,81 – 24,68 mm), tohum eni (10,70 – 14,80 mm), tohum kalınlığı (2,48 – 4,66 mm), 1000 dane ağırlığı (223,2 – 549,0 g) ve tohum verimi (101,99 – 165,01 kg/da) kriterleri genotiplere göre değişiklik göstermiştir. Genotipler arasında tohum şekli (dar eliptik, eliptik, geniş eliptik), tohum rengi (açık krem, krem, koyu krem), meyvede tohum çimlenmesi (var, yok), çıtlama kolaylığı (kolay, zor) açısından da farklılıklar beli ...Более
