Mycelial Compatible Groups of the Sclerotium rolfsii Isolates and Comparison of Morphological and Pathogenic Characters

Yıl 2019, Cilt: 48 Sayı: 1, 1 - 7, 15.02.2020

Öz

Sclerotium rolfsii Sacc. is a polifag soil-borne fungal pathogen. This research aims to find out the mycelial compatible groups (MCG) of S. rolfsii, the differences in pathogenicity and morphological characters. All isolates collected from diseased green beans in Çanakkale during September, 2015. Twenty seven isolates in total were paired with each other in potato dextrose agar (PDA) to determine mycelial compatible groups (MCG). Pairings were scored as mycelial compatible if sclerotia formed in the interaction zone, however pairings were scored as mycelial incompatible if a barrier occurred. Three MCGs were determined. There were statistical differences in means of mycelial growth, the number and diameter of sclerotia produced. The correlation analysis exhibited that there was a negative correlation between sclerotium number-mycelial growth and sclerotium number and sclerotium diameter; however there have been positive correlation between mycelial growth and sclerotium diameters. All isolates were found to be highly virulent on tested bean seedlings. This research shows that there is phenotypic variation among isolates of S. rolfsii.

Sclerotium rolfsii Sacc. polifag toprak kökenli fungal etmendir. Bu çalışmanın amacı S. rolfsii izolatları içinde miselyal uyum gruplarının (MUG), patojenisitelerinin ve morfolojik farklılıklarının saptanmasıdır. Tüm izolatlar Çanakkale’de fasulye üretim alanlarında, Eylül, 2015 tarihinde toplanmıştır. İzolatlar arasında MUG gruplarının saptanabilmesi için toplam 27 izolat patates dekstroz agar (PDA) ortamında eşleştirilmiştir. PDA üzerinde interaksiyon noktasında birleşme olur ve sklerot oluşumu gözlenirse etmen uyumlu, eğer çarpışma noktasında bariyer oluşursa uyumsuz olarak tanımlanmıştır. Eşleştirme sonucunda 3 MUG saptanmıştır. Misel gelişimi, sklerot sayısı ile sklerot büyüklüğü açısından izolatlar arasında istatistiki olarak farklıklar olduğu saptanmıştır. Yapılan korelasyon analizi sonucunda sklerot sayısı - misel büyümesi ve sklerot sayısı - sklerot çapı arasında negatif; misel büyümesi ile sklerot çapı arasında pozitif bir ilişki bulunmuştur. Tüm izolatların fasulyede yüksek oranda virulent olduğu saptanmıştır. Bu çalışmada S. rolfsii izolatları arasında fenotipik farklılıkların olduğu saptanmıştır.
