Abstract

In order to increase water use efficiency and drought resistant OLIVE cultivars selection for development of OLIVE cultivation in arid and semi-arid regions of Iran, an experiment was conducted to evaluate the growth and physiological responses of six Iranian native OLIVE cultivars (‘Zard', 'Roghani', 'Mary', 'Fishmi', 'Dezful' and 'Shenge') under DROUGHT STRESS. Two-year-old OLIVE plants were assessed in a split plot design based on complete randomized block design. Some characteristics such as STOMATA RESISTANCE and PROLINE level were measured under DROUGHT STRESS. For irrigation treatments, two-, six- and twelve-day treatments were selected and the two-day treatment was held for control. Results revealed that increase in irrigation intervals and DROUGHT STRESS degree had significant effects on STOMATA RESISTANCE, LEAF WATER POTENTIAL and PROLINE level. Conspicuously, leaf PROLINE level increased with increase in DROUGHT STRESS degree and this was seen in all cultivars of this study. The consequence with increase in irrigation intervals was improvemerit in STOMATA RESISTANCE and maximum STOMATA RESISTANCE was seen in 'Dezfuli' and 'Mary' cultivars. Results also showed that in all cultivars, LEAF WATER POTENTIAL decreased with higher DROUGHT STRESS and 'Mary' and 'Dezfuli' cultivars had minimum LEAF WATER POTENTIAL. There were significant differences among cultivars in STOMATA RESISTANCE and LEAF WATER POTENTIAL traits but there was not any significant difference in leaf PROLINE level trait. Results indicated that among cultivars used in this study, 'Dezfuli' and 'Mary' cultivars were resistant and 'Roghani' cultivar was susceptible to drought.
