Résumé
In this study, ecophysiological properties and responses to drought stress of selected woody species ; Fırat poplar (Populus euphratica Oliv.), Black locust (Robinia pseudoacacia L.), Tamarix (Tamarix parviflora L.), Joint-pine (Ephedra major Host), Oleaster (Elaeagnus angustifolia L.), Arabic almond (Amygdalus arabica L.), White saxaul (Haloxylon persicum) and Saltbush (Atriplex canescens) were investigated under natural conditions in Central Anatolia, Konya Soil, Water and Desertification Research Institue at vegetation periods of 2014 and 2015. Among this eight species, Haloxylon and Atriplex had higher assimilation rates. Moreover, these two species had lower water potential values. In this species vessel diameters, vessel numbers, lumen width, lumen height and bordered pits were measured. H. persicum and A. canescens had smaller vessels with ticker vessel walls, but had higher amount of vessels when compared to other species of this study. Also, gas exchange comparisons were made on selected by their availability four species (Robinia pseudoacacia, Elaeagnus angustifolia, Amygdalus arabica ve Atriplex canescens), which were grown under well watered and water stressed conditions in greenhouse at Kahramanmaraş Sütçü İmam University. In greenhouse trial, A. canescens had the highest assimilation rate, when compared to its counterparts. Thus, ecophysiological properties and adaptation capabilities of these species, which are also used for rehabilitation of arid and barren areas of Turkey were investigated and their conditions of us for further greening, restoration, rehabilitation and plantations recomended.
