Abstract

In order to investigate the effect of drought on some of the olive cultivars, a factorial pot experiment was conducted in a completely randomized design in Gilan-Gharb city of Kermanshah Province in open condition during 2015. The treatments consisted of three irrigation levels of 100% (control), 75% and 50% field capacity, and three olive cultivars (Zard, Amigdalolia and Conservolia). The results showed that vegetative growth such as plant height, Leaf number, leaf area and root length were significantly affected by water stress depending on the cultivar. peroxidase and catalase enzymes activity were significantly different between cultivars under water stress. The highest levels of peroxidase and catalase activity were observed in Conservolia cultivar at 50% irrigation treatment. The amount of phenol increased under water stress. ‘ Zard’ , ‘ Amigdalolia’ and ‘ Conservolia’ had the highest to lowest levels of phenol under stress treatments in compare to the control plants, respectively. The amount of Malondialdehyde in different treatments was significantly affected by drought stress. The highest increase of Malondialdehyde was observed in irrigation treatment of 50% in Zard cultivar with about 57% increment compared to control plants. Generally, according to the response of cultivars, they differed in drought tolerance, and each showed a specific response. Vegetative shoot growth under conditions of drought stress was higher in ‘ Zard’ compared to Conservolia and Amigdalolia cultivars. Zard cultivar was superior in terms of increase in phenol content and peroxidase and catalase activity, while ‘ Conservolia’ had the highest increase in sugar content.
