Abstract
This study was conducted to investigate some biochemical and physiological reactions of different olive cultivars (Olea europaea L.) against salinity stresses in three different experiments, experimental settings and contexts in Iran over a period of three years. In order to study the effects of salinity and penconazole combination on physiology of four olive cultivars, a factorial experiment was conducted. Studied factors were included of cultivar at for levels (Conservolea, Koroniki, Zard, Roghani), salinity stress (zero, 100 and 200 mM) and penconazole at three levels (zero, 10 and 15 mM). The results of the experiment showed that the studied treatments had significant effects on morphological factors, physiological factors, carbon dioxide levels, transpiration, stomatal conductance and photosynthesis rate of different olive cultivars. Among different cultivars, Koroniki and Zard showed higher resistance to salinity. The results of this research could be used in order to choose salinity-tolerant cultivars and cultivars with high oil quality to be used in agricultural, food, and pharmaceutical industries.
