مطالعه گرده افشانی و تعیین بهترین تلقیح کننده زیتون برای ارقام خودناسازگار زیتون در شرایط رودبار

Different olive cultivars in term of pollen compatibility are categorised to the four following groups: (l) Self-fertile cvs or self compatible, (2) Partially Self-fertile cvs (3) Self-steril cvs or Self incompatible (4) Andro-steril cvs or Male sterile cvs Therefore cross pollination is necessary for the last three groups for commercial production. The main objective of the study is determining the best pollinizer and types of pollination in S evill ana, Mission, Shengeh and Fishomy cultivars, this receprocal and open and self were carried out. This research arranged in Randomized Complete Block Design (RCBD) with four replication. In order to, on each tree in different orientation was selected 40-60 flowering branches with 20-30 in lenght, when flowers are become showen and bulge white , flowers were isolate with paper bags. In order to, study of Self- Pollination, four branches until end of full bloom is isolated and other branches were pollinated with three pollen grians. Performance measures include first and final friut-set and fertile and compatibillty index and final weight of fruits. Fruit numbers were acounted four stages (from intial fruit set to harvest) and measured average weight fruit. Index for fruitset of final aeount was investigated results showed that exists significant difference in self and open pollination in four cultivars, The largest amount of friutset percentage was found in Mission and Sevlliana and. the lowest in shengeh and Fishemi cvs. Fruitset in reciprocal pollination was not more than open pollination, so that mentioned cultivars pollen are not suitable for each others.
