TAILIEUCHUNG - Nickel hyperaccumulation in Bornmuellera kiyakii Aytaç & Aksoy and associated plants of the brassicaceae from Kızıldağ (Derebucak, Konya Turkey)

Recent exploration of an area of ultramafic geology in south-western Turkey led to the discovery and description of a new species, Bornmuellera kiyakii Aytaç & Aksoy (Brassicaceae). This was of particular interest to us because of the earlier discovery of nickel hyperaccumulation (Ni concentrations exceeding of plant dry weight) in 6 other taxa in this small genus from Albania, Greece, and Turkey. | Research Article Turk J Bot 33 (2009) 33-40 © TÜBİTAK doi: Nickel Hyperaccumulation in Bornmuellera kiyakii Aytaç & Aksoy and Associated Plants of the Brassicaceae from Kızıldağ (Derebucak, Konya-Turkey) Roger D.

This was of particular interest to us because of the earlier discovery of nickel hyperaccumulation (Ni concentrations exceeding of plant dry weight) in 6 other taxa in this small genus from Albania, Greece, and Turkey. We report herein that B. kiyakii is also a Ni hyperaccumulator, based on a population near Çamlık that showed a mean Ni –1 concentration exceeding 8000 mg kg of dried leaf material. Several other members of the Brassicaceae at the same site–species of Alyssum L., Pseudosempervivum (Boiss.) Grossh. (formerly in Cochlearia L.) and Thlaspi L.–also act as Ni hyperaccumulators. Key Words: Bornmuellera, nickel, hyperaccumulation Bornmuellera kiyakii Aytaç & Aksoy Türünde Nikel Hiperakümülasyonu ve Kızıldağ’dan (Derebucak, Konya-Türkiye) Brassicaceae Familyası Bitkileri Özet: Son yıllarda Türkiye’nin güneybatısında ultramafik bir alanda yapılan araştırmada, yeni bir tür olan Bornmuellera kiyakii Aytaç & Aksoy (Brassicaceae) keşfedilmiş ve tanıtılmıştır. Bu küçük cins içinde yer alan diğer altı taksonun (Arnavutluk, Yunanistan ve Türkiye’den) nikel hiperakümülasyonunun daha önce belirlenmiş olmasından dolayı, bu yeni tür özel olarak ilgimizi çekmiştir. Bu –1 makalede, Bornmuellera kiyakii’nin de bir nikel hiperakümülatör olduğu; kuru yaprak materyalinde ortalama 8000 mg kg üzerinde nikel .
