Fire-related cues (heat shock and smoke) and seed germination in a cistus creticus population in southwestern Turkey
Öz: Bu çalışmada Cistus creticus (Cistaceae) tohumlarının çimlenme davranışı ile yangınla ilişkili imler (ısı şoku ve duman) arasındaki ilişki laboratuvar şartlarında araştırılmıştır. Tohumlar, Türkiye'nin güneybatısındaki Muğla İli'nde yer alan Bozburun yarımadasında uzun süredir yangına maruz kalmamış bir Pinus brutia Ten. ormanından elde edilmiştir. Isı uygulamaları 80, 100, 120 ve 150°C'lerde beş dakika olacak şekilde gerçekleştirilmiştir. Duman uygulamaları için, tohumlar sıvı duman çözeltisinde 24 saat boyunca inkübe edilmiştir. Isı ve duman uygulamaları için, sırasıyla, kuru ve sulu kontroller deneye dâhil edilmiştir. Isı ve duman kombinasyonlarını içeren ek uygulamalar ve bir soğuk katlama uygulaması da yürütülmüştür. Uygulama geçiren ve geçirmeyen tüm tohumlar dolgu maddesi olarak agar içeren Petri tabaklarına yerleştirilmiş ve çimlenmeler deneyin sonunda kadar kontrol edilmiştir. Kontrollerle karşılaştırıldığında, 100, 120 ve 150°C'lik ısı şoklarının çimlenme cevabı üzerine uyarıcı etkisinin olduğu, 80°C'lik ısı şokunun, dumanın ve soğuk katlamanın ise olmadığı saptanmıştır. Isı uygulamaları ile ilgili sonuçlar mevcut literatür ile uyumludur, ancak duman uygulaması ile ilgili sonuçların kapsamlı bir şekilde karşılaştırılabilmesi için daha çok çalışma yapılmasına gereksinim vardır. Özet olarak, sonuçlar ele alınan C. creticus populasyonunda tohum çimlenmesinin orta ve yüksek ısı şiddetleri ile uyarılırken, düşük ısı şiddeti ve dumanla uyarılmadığını göstermiştir. Bitki türlerinin yangın imlerine çimlenme cevabının bilinmesi, yangına eğilimli orman ekosistemlerinde daha iyi yönetim kararları verebilmek için önemlidir.

Öz: This study investigated the relationship between fire-related cues (heat shock and smoke) and the germination behaviour of Cistus creticus (Cistaceae) seeds under laboratory conditions. The seeds were obtained from a long-unburned Pinus brutia Ten. forest located on the Bozburun peninsula, Muğla, Turkey. Heat treatments were carried out at 80, 100, 120, and 150°C for five minutes. For smoke treatments, seeds were incubated in a liquid smoke solution for 24 hours. Both dry and watered controls were included in the experiment for heat and smoke treatments, respectively. Extra treatments of heat and smoke combinations and a cold stratification treatment were also performed. The treated and untreated seeds were sown into Petri dishes containing agar as a substrate, and the germinations were monitored until the end of the experiment. When compared with the control, the heat shock of 100, 120 and 150°C had significant stimulatory effects on the germination response, whereas 80°C, smoke and cold stratification did not. The results of the heat treatments are in accordance with current literature, but there is still a need for more studies for the comparison of the smoke treatment. In summary, the results indicated that seed germination of the considered population of C. creticus is stimulated by moderate and high heat intensities, but not by low heat intensity and smoke. It is important to know the germination response of plant species to fire cues for better management decisions in fire-prone woodland ecosystems.
