Characterization of Pseudomonas syringae PV. syringae from diseased stone fruits in Kyrgyzstan and testing of biological agents against pathogen

Tinatin DOOLOTKELDİEVA | Saykal BOBUŞOVA

The plant diseases caused by the Pseudomonas syringae сomplex bacteria are economically important and occur worldwide on various plants, and it is as a pathogen that has not been the object of studies and little is known about its epidemiology in Kyrgyzstan. The conventional phenotypic (LOPAT, API tests) and PCR-assisted isolation were used for the identificationof Pseudomonas syringae pv. syringaе isolates from the affected organs of local stone fruits, such as peach (Prunus persica), cherry (Prunus subgen), apricot (Prunus armeniaca), and plum (Prunus salicina) samples taken from the Chy, Is ...Daha fazlası

The Effects of Arbuscular Mycorrhizal Fungi and Lead (Pb)Applications on Eggplant Seedling Growth and Nutrient Uptake

Mustafa PAKSOY | Önder TÜRKMEN

There are many factors, which negatively affect plant development. One of these factors is lead (Pb), which causes toxic effects on plants during the seedling period. Mycorrhizas (AMF) contribute positively to plant growth. In eggplant seedlings, it has been researched whether to tolerate the negative effects of lead with mycorrhizas. In the study, Gigaspora margarita (Gm) and Glomus intraradices (Gi) mycorrhizal races were applied before seeds were sown. After the first true leaves appeared, 5 different doses of Pb (0, 100, 200, 400 and 800 ppm) were given. As a result, the earliest true leaf ...Daha fazlası

Genetic Relationships and Population Structure of Central Asian Apple Species collected from Different Parts of Kyrgyzstan

Abdıkerim ABDULLAYEV

Apple is among the most widely grown fruit species worldwide. It is included in the genus Malus and there are several species of apple. Although a consensus is not available about the origin of domesticated apples, it is widely accepted that Malus sieversii, known as Central Asia wild apple, was the primary progenitor of apples. Central Asia is a quite significant origin center of apple and harbors different species and a great diversity. In this study, genetic relations among 79 apple materials belonging to 4 different species (M. domestica, M. sieversii, M. kirghisorum and M. niedzwetzkyana) ...Daha fazlası

Characterization and pathogenicity of Rhizoctonia isolates collected from Brassica oleracea var. acephala in Ordu, Turkey

İsmail ERPER

A total of 30 Rhizoctonia isolates were collected from plants with Rhizoctonia-like symptoms in kale growing areas in Ordu province during the 2014-2015 growing seasons. All the isolates were identified using nuclear staining tecnique and the nucleotide sequence analysis of the nuclear rDNA internal transcribed spacer (ITS)1-5.8S-ITS2 region. The most prevalent anastomosis group (AG) was AG 2-1 (36.67?f isolates), followed by AG-A (30? AG 4 HG-I (10? AG 5 (6.67? AG-Fb (6.67? AG-E (6.67?and AG-K (3.33?

Efficacy of the entomopathogenic fungi; Beauveria bassiana and Metarhizium anisopliae against the cowpea weevil, Callosobruchus maculatus F. (Coleoptera: Chrysomelidae: Bruchinae)

İsmail ERPER

The efficacy of the two entomopathogenic fungi, Metarhizium anisopliae (TR 106) and Beauveria bassiana (TR 217), was tested against the adults of the cowpea weevil, Callosobruchus maculatus F. (Coleoptera: Chrysomelidae: Bruchinae) in laboratory. Two concentrations of conidial suspensions (1 x 10(6) and 1 x 10(8) conidia/ml) of M. anisopliae and B. bassiana isolates were directly applied on four pairs of adult beetles in Petri dishes (2 ml/dish) and then incubated at two different climatic regimes; 22 +/- 1 degrees C and 26 +/- 1 degrees C with 70 +/- 5% RH, 16:8 h light-to-dark.

EFFECTS OF NITROGEN FERTILIZATION RATES ON FORAGE YIELD AND QUALITY OF ANNUAL RYEGRASS (LOLIUM MULTIFLORUM L.) IN CENTRAL BLACK SEA CLIMATIC ZONE IN TURKEY

Selahattin ÇINAR

In this research, we aimed to determine the effects of nitrogen fertilization on forage yield and forage quality of annual ryegrass (Lolium multiflorum L.) in Kazova, Tokat/Turkey conditions (the Central Black Sea Climate Zone) in 2014/2015 and 2015/2016 growing years. The experiment consisted of four replications in randomized complete block design to test effect of seven nitrogen rates (0, 50, 100, 150, 200, 250, 300 kg ha(-1)) on plant height (PH), fresh forage yield (FFY), dry matter yield (DMY), crude protein ratio (CP), crude protein yield (CPY), Acid Detergent Fiber (ADF) ratio, Neutral ...Daha fazlası

DETERMINATION OF BOTANICAL COMPOSITION, HAY YIELD AND FORAGE QUALITY OF SOME NATURAL RANGELANDS IN KYRGYZSTAN'S CHUY REGION

Selahattin ÇINAR | Abdıkerim ABDULLAYEV

This research was carried out in 2018 in order to determine the hay yields, forage qualities botanical compositions and range conditions of 5 different natural rangelands located at different altitudes the Chuy Region, Kyrgyzstan. In the rangelands, the ratio of plant coverage was 96.0-98.0%, the ratio of grasses, legumes, other plant families in the plant covered area was 24.5-48.1%, 4.7-24.0%, 36.2-63.8%, respectively. In the rangelands, the rate of decreaser, increaser and invader species was 37.0%, 7.3% and 55.7%, respectively. The average dry matter yield (DMY) of all five ranges was 2904 ...Daha fazlası

Some Morphological Characteristics of Gene Pool from the Hybridization of Local Tomato Genotypes and Some Commercial Types

Mustafa PAKSOY | Önder TÜRKMEN

Determination of different gene sources is important for plant breeding studies; therefore, local genotypes are of interest. In this study, collected genotypes were hybridizied with commercial genotypes in order to transfer some traits such as disease resistance and long shelf life to local genotypes. After that, obtained genotypes were self pollinated twice and gene pool was created according to some morphological traits. Nine different groups were created from combinations according to result of clustering analysis. Result of principal component analysis (PCA) revealed that total rate of 65. ...Daha fazlası
