Fungi Associated with Cysts of Globodera rostochiensis, Heterodera cruciferae and Heterodera schachii (Nematoda: Heteroderidae)

Öz

Cysts of Globodera rostochiensis (Wollenweber) Behrens from potato (Solanum tuberosum L.) fields and Heterodera cruciferae Franklin from cabbage (Brassica oleracea L. var. capitata subvar. rubra L.) fields and Heterodera schachtii Schmidt from sugar-beet (Beta vulgaris L.) fields in Turkey were collected and examined for the presence of fungi. Of the total of 196 cysts of G. rostochiensis, 39.7% were colonized by one or more of 7 different species of fungi, all of which were from the genera Cylindrocarpon, Fusarium, Gliocladium, Verticillium and Alternaria. Of the total of 136 cysts of H. cruciferae, 37.5% were colonized by one or more of 7 different species of fungi, all of which were from the genera Cylindrocarpon, Fusarium, Nematophthora, Periconia and Verticillium, and 38.9% of the 154 cysts of H. schachtii were colonized by one or more of 7 different species from the same genera.

Türkiye’de patates (Solanum tuberosum L.) tarlalarından Globodera rostochiensis (Wollenweber) Behrens, lahana (Brassica oleracea L. var. capitata subvar. rubra L.) tarlalarından Heterodera cruciferae Franklin ve şeker pancarı (Beta vulgaris L.) tarlalarından Heterodera schachtii Schmidt kistleri toplanmış ve mantar mevcudiyeti bakımından incelenmiştir. Toplam 196 G. rostochiensis kistinin 39.7% si 7 farklı türe ait bir ya da daha fazla mantar türü ile beraber bulunmuştur. Bu mantar türleri, Cylindrocarpon, Fusarium, Gliocladium, Verticillium ve Alternaria cinslerine aittir. Toplam 136 H. cruciferae kistinin 37.5% i 7 farklı türe ait bir ya da daha fazla mantar türü ile beraber bulunmuş olup bunların hepside Cylindrocarpon, Fusarium, Nematophthora, Periconia ve Verticillum cinslerine ait mantar türleridir. H. schachtii ye ait toplam 154 kistin 38.9% u ise yine aynı şekilde bir önceki cinslere ait olan mantarlar ile ilişkili olarak bulunmuştur
