Abstract

Pinus brutia Ten., Red pine, known to be tough drought resistant pine specie, could effectively be used for afforestation of disturbed areas. It is of great interest for the afforestation in arid zones. Appropriate seed sources for the specific areas guarantees reforestation success. Away from its native areas Pinus brutia Ten. is planted for its ornamental value and timber production purposes. Selection of drought resistant provenances can very well increase the survival success. In this study, the effects of water potential on germination were studied in fourteen provenances of Pinus brutia Ten. from Turkey. Water potentials between 0 and -8 bars were obtained using polyethylene glycol 6000 (PEG-6000) solutions. Seeds were kept for 35 day at 20 ± 0.5°C. A decrease in water potential produced a marked reduction in germination percentage and germination value. As a result, significant variations between the provenances were found. It was determined that, under a -8 bar water stress, Isparta-Bucak and Mersin-Silifke, respectively corresponding to 58% and 57% of the control group, were the least water stress affected provenances.
