The aim of the present study was selection of adaptable species with proper growth and wood production and resistant to cold with the aim of wood production and cultivation in the urban green space and infertile lands of Saveh. Seedlings of Eucalyptus suggrandis ssp. Suggrandis, E. microcarpa, E. suggrandis ssp. Alipe, E. camaldulensis 41-sh, E. camaldulensis var. camaldulensis, E. rubida 166-sh, E. viminalis 168-sh, E. sargentii and E. camaldulensis 41-ch were planted in 3×3m spacing on late March 2010 in three replications with 25 seedlings based on Randomized Complete Block design (RCB). Also, some physic-chemical properties of soilwere examined. Results of the data analysis showed that the maximum total height, crown diameter and trees quality were observed in E. camaldulensis 41-sh. While E. viminalis 168-sh showed maximum diameter at breast height and E. camaldulensis 41-ch the heigheststanding stock volume, volume increment and quality in compare to other species. Eucalyptus suggrandis ssp. Suggrandis, E. camaldulensis 41-sh and E. microcarpa were most resistant to cold. The maximum rate of survival was measured in E. sargentii and the lowest in E. rubida 166-sh. Total height was found to be the most important factor in extraction data variance. E. camaldulensis is recommended for wood production and E. sargentii is suggested for soil and water conservation in infertile lands of Saveh.
