Abstract: 

To determine the suitable pollinator for olive, cv. ‘Dezful’ among Manzanilla, Sevilana, Kalaman, local Gorgan 2 and local Gorgan 3 cultivars, this study was accomplished in Safiabad Agricultural Research Center for 2 years. The experimental design was Randomized Complete Blocks with four replications. Cross pollinations were carried out on four ‘Dezful’ cv. trees having the same situation and, the fruit set was measured at stone hardening period. The results showed that the kind of pollen affected ‘Dezful’ cultivar fruit set and cross pollination could increase fruit set significantly (p<0.01). Comparison of fruit set means in different treatments showed that 21.49 and 31.23 percent of ‘Dezful’ pistils pollinated by pollens of ‘local Gorgan 2’ and ‘local Grgan 3’ cultivars in first and second examined years were fertilized respectivily, while only 7.78 and 9.02 percent of self pollinated ‘Dezful’ pistils were fertilized, therefore, apparently self incompatibility exists in ‘Dezful’ olive. Analysis of combined two years showed that the annual effect on fruit set in ‘Dezful’ was not significant. The effect of pollination on oil content of fruit was not significant in different treatments, varying between 51.3 and 54 percent in dry matter. Study of flowers in ‘Dezful’ cultivar showed that the ratio of perfect and imperfect flowers from year to year was not the same and about 20 –34 percent of flowers were perfect. Fruit set of all flowers with open pollination was 3.04 – 3.4 percent.
