Abstract :None of the known native actinorhizal species in Turkey, Alnus glutinosa and A. orientalis insert ignore into journalissuearticles values(Betulaceae);, Datisca cannabina insert ignore into journalissuearticles values(Datiscaceae);, Elaeagnus angustifolia and Hippophae rhamnoides insert ignore into journalissuearticles values(Elaeagnaceae);, and the widely-planted exotic Casuarina cunninghamiana insert ignore into journalissuearticles values(Casuarinaceae);, have confirmed records of actinorhizae in Turkey. This study determined the capacity of representative actinorhizal plants in Turkey to form nodules, cluster roots and ectomycorrhizal roots in a typical central Anatolian soil with and without amendment of soil and nodule extracts, as well as in soil from Adana and Izmir. Nodulation was confirmed experimentally for E. angustifolia and C. cunninghamiana in Niğde soil insert ignore into journalissuearticles values(the latter only with addition Adana or Izmir soil);, but only observationally for A. glutinosa during sample collection in Rize. Cluster roots developed strongly in C. cunninghamiana, and likewise ectomycorrhizal roots in Allocasuarina verticillata insert ignore into journalissuearticles values(included as a reference species); but only to a lesser extent in C. cunninghamiana. The nodulation status of the natives, D. cannabina and H. rhamnoides, remains to be investigated.
