Özet
Bu çalışmada, Doğu Akdeniz bölgesinde bulunan kızılağaç (Alnus glutinosa (L). Gaertn)’ın relikt popülasyonlarının tohum özellikleri araştırılmıştır. Kahramanmaraş, Osmaniye ve Adana illerinde 6 relikt popülasyondan (Suçatı, Türkoğlu, Andırın, Düziçi, Kozan, Karaisalı) 2012 ve 2013 yıllarında kozalak temin edilmiştir. Laboratuvarda kozalakların morfolojik özellikleri ve bu kozalaklardan elde edilen tohumların 1000-dane ağırlıkları, morfolojik özellikleri, doluluk oranları, çimlenme yüzdeleri, çimlenme hızları ile yıllar arası farklılıklar araştırılmıştır. Tohumlar 0, 2, 4, 6, 8 hafta katlama işlemi sonrasında 24°C’de çimlenme testine alınmıştır. Ayrıca, doğal popülasyonlarda da gözlemler yapılmıştır. Ortalama kozalak boyu 17.89 mm, çapı 9.95 mm, ağırlığı 0.49 gr; ortalama tohum boyu 2.64 mm, eni 2.31 mm, kalınlığı 0.73 mm olarak ölçülmüştür. Genel ortalama dolu tohum oranı %42.0 olarak bulunmuştur. Ortalama 1000-dane ağırlığı 1.24 gr olarak belirlenmiştir. En yüksek çimlenme yüzdesi (%64.0) Kozan popülasyonunde elde edilmiştir. Ortalama çimlenme yüzdesi %26.7, ortalama çimlenme hızı 4.1 gündür. Genel olarak tohumlardaki derin olmayan dormansinin giderilmesi için 2 ile 4 haftalık katlama işlemi yeterli olmuştur.
In this study, seed characteristics of Common alder (Alnus glutinosa (L).Gaertn.) relict populations in the Eastern Mediterranean Region were investigated. The cones of the species were collected from six different relict populations (Sucati, Turkoglu, Andirin, Düziçi, Kozan, Karaisalı) in Kahramanmaraş, Osmaniye, and Adana provinces in both 2012 and 2013. In the laboratory, the morphological characteristics of cones and seeds, percentage of sound seeds, and 1000-seed weight were researched. Dormancy existence and depth, germination percentages, germination speed, and the differences between the years (2012 and 2013) were also determined. The seeds were taken to germination tests after 0, 2, 4, 6, 8 weeks of prechilling at 24°C. The relict populations in the region were also observed in terms of development, regeneration, and sustainability. Average cone length, cone diameter, cone weight, seed lentgth, seed width, and seed thickness were 17.89 mm, 9.95 mm, 0.49 g, 2.64 mm, 2.31mm, and 0.73 mm, respectively. Overall average sound seed percentage was found to be 42.4%. Average 1000-seed weight of six populations was 1.24 g. The highest germination percentage (64.0%) was obtained in Kozan provenance. The average germination percentages and mean germination times of populations in both years were 26.7% and 4.1 days, respectively. In general, about 2 or 4 weeks of prechilling was sufficient to eliminate the nondeep seed dormancy.
