The objective of this study was to determine the principles and methods of synthetic pollination when pollen was not sufficient or female and male trees pollination period was not suitable in the pistachio fields.
Materials and Methods
This study was carried out using Pistacia vera L. rootstocks which was budded on 30 to 35 years old female trees. 16 trees within the 30 trees were changed year to year due to periodicity. Pollen of25-30 years old hybridised male trees which were obtained from P. vera seeds was used as a source of pollination. Pollen of male flowers mixed with 1% and 4% flour was distributed to the trees isolated with thin tent by atomiser and fabric bags a week before blooming.
Results
This research was done to find a solution to insufficient pollination happened in the pistachio fields. The results of this study showed that utilisation of 1 g of pollen was found to be sufficient enough when 1% pollination occurred in the female pistachio tree. Homogenous distribution of pollen to the female trees was obtained by mixing with 1% hard and soft wheat flour. Sufficient fruits was obtained by distribution of this mixture with atomiser or thin cotton bags at one times. Application of pollen at one times when 1% pollination occurred or two times when 1% and 40% pollination occurred and natural pollination were found to be not statistically significant.
