Abstract

: In this study, the mycelial growth of 11 isolates belonging to the Botryosphaeriaceae species Botryosphaeria dothidea (walnut, almond, olive, grapevine), Neofusicoccum mediterraneum (walnut, almond), Neofusicoccum parvum (walnut, olive, grapevine), and Dothiorella sarmentorum (almond) was evaluated under varying temperature regimes. The cardinal temperatures (Tmin, Topt, and Tmax) of the isolates were determined. The isolates were cultured at eight temperatures ranging from 5 to 40°C, and colony diameters were measured. Temperature-dependent growth parameters were estimated using the Analytis Beta model. Additionally, mycelial growth rates of the isolates were calculated and compared. The results revealed statistically significant differences among isolates in optimum and maximum growth temperatures, as well as growth rates. The highest optimum temperature (33.2°C) was recorded for a B. dothidea isolate, while N. mediterraneum isolates exhibited relatively high optimum temperatures ranging from 28.4 to 29.7°C. Overall, Neofusicoccum species displayed the highest mycelial growth rates. In contrast, D. sarmentorum exhibited the lowest optimum and maximum temperature values. These findings support that Neofusicoccum species possess a greater capacity for adaptation to warm conditions and suggest that disease risks associated with these pathogens may increase under climate change scenarios. The thermal parameters obtained in this study may contribute to the development of disease forecasting models and the design of sustainable disease management strategies.

Özet

Bu çalışmada, Botryosphaeriaceae familyasına ait Botryosphaeria dothidea (ceviz, badem, zeytin, bağ), Neofusicoccum mediterraneum (ceviz, badem), Neofusicoccum parvum (ceviz, zeytin, bağ) ve Dothiorella sarmentorum (badem) türlerine ait 11 izolatın farklı sıcaklık aralıklarındaki miseliyal gelişimleri incelenmiş ve kardinal sıcaklık değerleri (Tmin, Topt, Tmax) belirlenmiştir. İzolatlar, 5–40°C arasındaki sekiz farklı sıcaklıkta yetiştirilmiş, koloni çapları ölçülmüş ve sıcaklığa bağlı gelişim parametreleri Analytis Beta modeli kullanılarak hesaplanmıştır. Ayrıca, izolatların miseliyal gelişme oranları karşılaştırılarak analiz edilmiştir. Elde edilen sonuçlar, izolatlar arasında optimum ve maksimum gelişme sıcaklıkları ile büyüme hızları bakımından istatistiksel olarak anlamlı farklılıklar olduğunu ortaya koymuştur. En yüksek optimum sıcaklık değeri 33.2°C ile bir B. dothidea izolatında tespit edilirken, N. mediterraneum izolatlarının 28.4–29.7°C arasında nispeten yüksek optimum sıcaklıklara sahip olduğu gözlemlenmiştir. Neofusicoccum türleri, genel olarak en yüksek miseliyal gelişme oranlarını sergilemişlerdir. Buna karşılık, D. sarmentorum en düşük optimum ve maksimum sıcaklık değerlerini göstermiştir. Elde edilen bulgular, Neofusicoccum türlerinin sıcak koşullara daha yüksek adaptasyon kapasitesine sahip olduğunu ve iklim değişikliğinin etkisiyle hastalık risklerinin potansiyel olarak artabileceğini desteklemektedir. Elde edilen termal parametrelerin, hastalık tahmin modellerinin geliştirilmesinde ve sürdürülebilir mücadele stratejilerinin oluşturulmasında faydalı olacağı değerlendirilmektedir.
