Bu çalışmada, Gaziantep ve Şanlıurfa illerinin Nizip ve Birecik ilçelerinde 2018-2020 yılları arasında 10 farklı bahçede 10 yaş üzerindeki antep fıstığı ağaçlarında solma, dal kuruması ve geriye doğru ölüme neden olan patojenler araştırılmıştır. Fusarium oxysporum, Fusarium equiseti ve Fusarium solani fungus türleri, Gaziantep ili Nizip ilçesinde antep fıstığı ağaçlarında yapraklarda küçülme ve solmalara, taç ve dallarda kurumalara, köklerde ise çürüklüğe neden olmuştur. Fungus türleri, koloni rengi, konidilerin morfolojik karakterlerine göre ve ITS gen dizilerinin NCBI gen bankasındaki diğer genlerle eşleştirme analizleri ile tanımlanmıştır. Şanlıurfa ili Birecik ilçesinde antep fıstığının solgunluk ve dal kurumasına neden olan patojen, ITS dizisi analizi ve konidiyal morfoloji özellikleri ile Neoscytalidium dimidiatum fungus türü olarak tanımlanmıştır. Bu fungus türlerinin, Güneydoğu Anadolu Bölgesin’nde antepfıstığı ağaçlarında hastalık etmeni olduğu, dal ve fidan patojenisite testi ile kanıtlanmıştır.
In this study, in the Nizip and Birecik districts of the provinces of Gaziantep and Shanlıurfa, between 2018-2020 years in 10 different gardens over the age of 10 have been investigated pathogens that lead to swelling, branch drying and backward death in the tree of anthropic beans. Fusarium oxysporum, Fusarium equiseti and Fusarium solani fungus species, in the province of Gaziantep or Nizip, have caused redundance and swelling in the leaves in the antep beans trees, drought in the crowns and branches, and corruption in the roots. Fungus species, colonial colour, are defined according to the morphological characteristics of conids and by the analysis of matching the ITS gen series with other genes in the NCBI gen bank. In Sanlıurfa or Birecik district, the pathogen, which causes flushing and branch drought of the antep bean, is defined as the type of Neoscytalidium dimidiatum fungus with the analysis of the ITS series and the characteristics of the conidial morphology. These species of fungus have been proven to be sick in the antipestic trees in the southeastern Anadolu region, with a branch and fidan pathogenicity test.
In this study, fungal pathogens were investigated on over 10-yrs old, pistachio trees that displayed wilting, drying of branches, dieback, and root rot in 10 different orchards in Nizip and Birecik counties of Gaziantep and Şanlıurfa provinces respectively between 2018 and 2020. The fungal species, Fusarium oxysporum, Fusarium equiseti and Fusarium solani caused stunting and wilting of leaves, drying of the branches, and, dieback of trees with root rot in Nizip county of Gaziantep province. Fungi species were identified by colony color, morphological characteristics of conidia, and alignment analyses of ITS gene sequences with other genes in the NCBI gene bank. The causative agent of a wilting and dead branch of pistachios in Birecik county of Şanlıurfa province was identified as Neoscytalidium dimidiatum which was determined by the conidial morphology and nucleotides alignment of the ITS gene. Fungal species have been proven to be disease agents of pistachio trees in Southeastern Anatolia by pathogenicity test of cutting segments of branches and trees.
