Comparison of Some Olive Cultivars in Isfahan Conditions for Using in LandscapeAbstract Urban landscape an important component of urban ecosystems provide many environmental andsocial services that contribute to the quality of life in cities Trees specially evergreens use carbondioxide and release oxygen reduces air pollution through the year provide shade and theirtranspiration cools air and improve urban ecosystems Olive is a prennial evergreen tree which hasgood adaptibility to poor environmental conditions It is more salt drought and cold tolerant than othersimilar fruit trees and is considered less demanding in term of nutrients and energy inputs than otherfruit crops In recent years there is a tendency to plant olive trees in green spaces So this study wascarried out to evaluate 15 olive cultivars regarding form texture and color and also frost resistance torecommend for landscape and green areas of Isfahan A randomized block design experiment was doneusing Konservalia Manzanilla Spain Dezful Shengeh Bleidi Rashid Valanolia Zard Kroneiki Sevillana Roughani Gorgan Mishen Amphissis Factors measured in first experiment include treeheight tree canopy height width extent canopy volum trunk diameter angle between branches branch growth number of lateral branches on one year old shoots length width area shape index andcolor of leaves length diameter and index of fruit shape Results showed a larg genetic diversitybetween cultivars A cluster analysis was done using seven factors effective on tree texture leaf area length width ratio of leaves color of leave angle between trunk and scaffolds angle between currentyear with one year old branch canopy volum and number of lateral branches and also on seven factorseffective on tree form tree height width extent height extent of canopy angle between trunk andscaffolds angle between current year with one year old branch growth of current year branches andnumber of lateral branches The results showed that Manzanilla Spain and Amphisis perform widthoval form and medium and fine texture so could apply for background screen and group planting Roughani Mishen Valanolia Gorgan Kroneiki Zard and Sevillana show round form and mediumtexture could apply for specimen tree to planting in lawn Rashid cultivar with long height long ovalform and coarse texture is a good selection to accent plant and for screen and frame In secondexperiment with the aim of determination of cold tolerance cultivars visual method in years of 2007and 2008 and chlorophyll fluorescence measurment was used Results in two methodes was relativelike together Results showed that Amphisis Shengeh and Gorgan were frost tolerant cultivars whichtolerate temperature reduction to 15 and Rashid Kroneiki Valanolia and Spain were sensitivecultivars to low temperatures 10 centigrade degree and lower In addition most of olive cultivarsstudied could be use in Isfahan green space and cities with similar temperature condition In regionsthat temperature reduce to 10 to 15 centigrade degree for several days it is better that use tolerantcultivars Cold damages on tree shoots could be recover following light pruning Key wordsOlive landscape frost resistance chlorophyll fluorescence
