Abstract

The Australian tree, Casuarina cunninghamiana Miq. (Casuarinaceae), is widely planted for agroecosystem and other benefits, and belongs to a family (sheoaks) with wide adaptation and tolerance to environmental extremes. However, extreme cold as a stressor is not common on the Australian continent, so compared to heat and drought, less work has been done on the cold tolerance of Australian flora. Therefore, saplings of C. cunninghamiana were exposed to 0 to 4 months of extreme winter temperatures below -5°C to about -15°C over 2 years in Niğde, Central Anatolia, Turkey to test their cold sensitvity. Damage was severe, however, most plants exposed to 1 or 2 months of the milder temperatures (down to -5°C) at the beginning of winter recovered. Four months exposure killed all the plants. However, even the milder, early-winter conditions are unlikely to be suitable for the long-term productivity or survival of C. cunninghamiana and perhaps all members of its family. The risk of extreme cold needs to be considered when planting sheoaks beyond their native range.

Abstract

Avustralya ağacı, Casuarina cunninghamiana Miq. (Casuarinaceae) geniş bir adaptasyon ve çevresel uç noktalara toleransı olan bir familyaya (demirağacıgiller) ait olup, agroekosistem ve diğer faydalar için yaygın olarak yetiştirilmektedir. Bununla birlikte, Avustralya kıtasında aşırı soğuk bir stres etkeni olarak yaygın olmadığıdan, Avustralya florasının soğuğa toleransı üzerinde ısı ve kuraklığa kıyasla daha az çalışma yapılmıştır. Bu nedenle, C. cunninghamiana fidanları, soğuk toleranslarının belirlenmesi için Niğde’de (Orta Anadolu, Türkiye) 0 ila 4 ay süreliğine -5°C'nin altında ve yaklaşık -15°C'ye kadar aşırı düşük kış sıcaklıklarına 2 yıl boyunca maruz bırakılmıştır. Hasar şiddetli olmakla birlikte, kış başlangıcından itibaren 1 veya 2 ay daha ılıman sıcaklıklara (-5°C'ye kadar) maruz kalan bitkilerin çoğu toparlanmıştır. Dört aylık maruz kalma, tüm bitkilerin ölümüne neden olmuştur. Bununla birlikte, daha ılıman, erken kış koşullarının bile, C. cunninghamiana'nın ve belki de bu familyaya ait diğer tüm türlerin uzun vadeli üretkenliği veya hayatta kalması için uygun olması pek olası değildir. Kendi doğal aralığının ötesinde demirağacıgilleri dikerken aşırı soğuk riskinin dikkate alınması gerekmektedir.
