Effect of Pollination supplementation on quantitative and qualitative characteristics of three varieties of pistachio commercial in Qazvin province

One of the most basic issues in pistachio orchard, pollination is suitable inoculation.
Therefore, with regard to non-compliance with the ratio of male to female as well as due to the low yield of pistachio trees in Qazvin province, Artificial pollination ( Supplementary) in pistachio orchards studied. In this experiment, two varieties of local-causing pollen that are Pollinators on different spray three Cultivars of Owhadi Qazvini, Akbari was used.
The test has two factor , a factor Cultivars (kaleh bozy, Owhadi, Akbari) on 3 levels and the pollen donor (A, B and Free) in three levels, a total of 9 treatments in 3 replications of each unit with a choice of two clusters of flowers in two north and a total of 54 South split plot experimental unit was.
Finally, after data entry operations, analysis of variance and Duncan mean comparison method were performed with SAS software and MSTATC.
The results showed that the number of supplementary pollination of fruit per cluster and the positive effects of the reduction of percentage blank. The best male tree pollen for pollination pollen local GA was at flowering 50%. Pollination not only are quantitative (number of flowers per cluster and the dry weight of pistachio kernel) increased, but also qualitative characteristics such as percent blind respectively in pistachio Akbari, Owhadi and kaleh bozy reduced.
