The Investigation of Drought Resistance in Wood Species for Isfahan Greenery Development

No doubt that in modern cities the greenery and city environment are the major rules for sustainable natural and human life. The increase air pollution and cityʹs developments necessitates the increase of cityʹs greenery. During the recent years due to shortage of water the Isfahan cityʹs greenery faced a lot of problems which make the cityʹs officials to worry about them. The shortage of water especially for greenbelts located in cityʹs boundaries is more obvious. The present study designed, to select the new and drought resistant species according to their leaf water potential. Five places of Zagrosian and Albours forests selected in order to select the drought resistant species according to their leaf water potential (LWP). The result showed that there are significant differences between the plant species. According to our studies the Quercus brantii, Quercus infectoria, Lonicera nummularifolia and Fraxinus rotundifolia species were recognized as the most drought resistant species and Cornus mass, Cornus australis, Sorbus torminalis, Sorbus umbellate and Celtis caucasica are the middle sensitive to drought Platanus orientalis Salix alba, Populus nigra and Populus alba species are the most sensitive to drought.
