Özet
This research was carried out on two years old olive (cv Ayvalik) trees grown in pots at field condition in Bornova Olive Research Station, Ministry of Food Agriculture and Livestock in 2011. Some morphological and physiological response of young olive tree to drought stress under different irrigation levels were investigated. For this reason, the experiment consisted of 4 treatments: 1) Irrigated at the level of 100% of the ETa (I-100), 2) Irrigated at the level of 66% of the ETa (I-66), 3) Irrigated at the level of 33% of the ETa (I-33), 4) Non-irrigated (I-0). Some physiologic responses of plants such as chlorophyll content (SPAD), stomatal conductance (g(s)), leaf temperature and air temperature difference (T-y-T-a) and also morphologic responses of the plant the trunk diameter, plant height, shoot diameter, shoot length were investigated. Irrigation water requirement was ranged from 0 to 82.45 liters/plant and actual evapotranspiration was ranged from 10.78 to 86.11 liters/plant. There were not a statistically significant difference among the treatmentsts (except I-0) in terms of morphological parameters. In terms of chlorophyll content, statistically significant differences were not found among the treatmentsts (except I-0), however, the leaf-air temperature differences and stomatal conductance values statistically significant differences were found among the treatmentsts. Ayvalik olive, is a drought-tolerant cultivar, recommended for growing in arid or water shortage areas. However, as a proposal determining the level of water stress in olive stomatal conductance and leaf and air temperature difference measurements can be used.
