Pectobacterium spp. geniş bir konukçu yelpazesine sahip, her ortamda bulunan bakteriyel bitki patojenlerden biri olup, istila ettiği bitki dokusunda Bakteriyel Yumuşak Çürüklük olarak bilinen hastalığa neden olur. Bu çalışmada 2018-2019 yılları arasında Yozgat Merkez ve Kırşehir Kaman ilçesindeki yerel pazar, manav ve zincir marketlerde satışa sunulan patates yumrularında bakteriyel yumuşak çürüklük hastalığına neden olan Pectobacterium spp. izolasyonu, biyokimyasal, patojenisite ve moleküler yöntemlerle tanılanması amaçlanmıştır. Survey yapılan market ve manavlardan 168 yumru örneği toplanmıştır. Tipik yumuşak çürüklük belirtisi gösteren ve göstermeyen şüpheli yumrularda pektolitik izolatların varlığının araştırılması amacıyla nemli hücre testi yapılmıştır. Çürüme belirtileri gösteren 54 farklı yumru kesitlerinden pektolitik izolatların izolasyonu Kristal Violet Pektat (CVP) besiyeri üzerinde yapılmıştır. CVP besi yerinde çukur oluşturan pektolitik koloniler NA besi yerine saflaştı...

Bazı Patates Klonlarının Alternaria solani’ye Karşı Dayanıklılıklarının Belirlenmesi
Yüzüncü Yıl Üniversitesi Tarım Bilimleri Dergisi, 2022
One of the most important problems in the cultivation of potato plants is their susceptibility to diseases. There are many disease agents that cause significant loss in yield and limit cultivation. One of these agents is Alternaria solani (Ell. and G. Martin) Sor., a facultative saprophytic fungus. The pathogen fungus causes early blight disease in potatoes. In this study, which was carried out in the field and laboratory of the Central Black Sea Transition Zone Agricultural Research Institute in 2019, the reactions of 594 clones created by crosses between some commercially registered potato varieties, local potato varieties, and some clones with superior characteristics against A. solani were identified using the detached leaf method. In order to determine the disease reactions, 5 mm diameter fungus discs taken from the actively growing tips of the cultures of A. solani isolate under sterile conditions were placed on the leaflets in five replications, and only the PDA medium was pl...

The frequency of growth cracks, secondary growth, knobby, dumbell, internal necrosis, vascular discoloration, hollow heart and bruise varied with genotypes. Vittorini, ilona, Fambo and Famosa were usually free of any disorders. Alisa, Famosa, Fambo and Rex were high yield health tuber genotypes.
Erzurum ilinde patates tarlalarında Fusarium türlerinin alternatif yabancı ot konukçuları
Bitki Koruma Bülteni, 2019
This study was carried out to determine the alternative weed hosts of Fusarium spp. in potato fields in Erzurum province. Isolations were made from 15 weed species (Amaranthus retroflexus, Anchusa arvensis, Avena fatua, Centaurea depressa, Chenopodium album, Cirsium arvense, Convolvulus arvensis, Euphorbia spp., Hibiscus trionum, Lallemantia canesces, Linum bienne, Malva grandfolia, Polygonum lapathifolium, Sinapis arvensis and Tragopogon buphthalmoides) and 83 isolates of Fusarium were obtained from roots and/ or stems of the weeds. These isolates were recognized as Fusarium equiseti, Fusarium oxysporum, Fusarium solani, Fusarium acuminatum and Fusarium avenaceum in the rates of 44.6%, 37.3%, 12.1%, 4.8% and 1.2% respectively. As a result of pathogenicity test conducted on potato plants (cv. Marfona), F. oxysporum and F. solani isolates were found to have the highest disease severity.

Tomato (Lycopersicum esculantum Mill) production has the first place among the vegetables, grown in the World as well as in Turkey. Especially as a row material tomato production for the food industry, Marmara Region of Turkey is the most important part of the country. But recently some sistemic virus infections have caused significant damages on leaves and fruits reducing yield and quality drastically. In order to observe virus infections and determine those viruses, survey visits were implemented at 3 tomato grower districts of Bursa and Yalova provinces in Marmara Region during the year of 2014. At the end of the surveys at least 94 tomato leaf samples were collected from the tomato plants exhibiting chlorosis, necrosis, mosaic. By employing Double Antibody Sandwich Enzyme-linked Immunosorbent Assay (DAS-ELISA) tests Tomato spotted wilt virus (TSWV), Cucumber mosaic virus (CMV) and Tomato mosaic virus (ToMV) viruses were searched in leaf samples. As a results of DAS-ELISA tests 19 out of 94 at the rate of 20.21 % tomato leaf samples were found infected with CMV, 21 of 94 samples at the rate of 22.34 % had ToMV and 2 out of the tomato leaf samples at the rate of 2.13 % were found infected with TSWV individually. As a mixed infections 19 out of 94 samples at the rate of 14.89 % had both CMV+ToMV, 4 of 94 samples at the rate of 4.26 % were found infected with CMV+TSWV, only 1 sample at the rate of 1.06 % had ToMV+TSWV as 4 out of 94 samples at the rate of 4.26 % were found infected with the mixture of CMV+ToMV+TSWV viruses.
