Abstract: (18732 Views)
Experiments were conducted during 1996-1997 in Nough of Rafsanjan to evaluate double pollination on fruit set and development of pistachio nut. In the first experiment, Owhadi cultivar was pollinated by a combination of pollen from Beneh (P. mutica F&M), Atlantica (P. atlantica Desf) and Soltani (P.vera L.). In the second experiment, Owhadi cultivar was pollinated by pollen from Beneh, Atlantica and Khinjuk (P. Khinjuk). The results showed that in the double pollination experiment, the nut, kernel and fruit set were affected more by the first pollen than by the second one. Pollen from the wild pistachio species reduced kernel weight, number of split nuts but increased percentage of the deformity and blank nuts in Owhadi. It was concluded that the effectiveness of the first pollen on fruit set, nut and kernel development was independent of the second one. The pollen of P. vera proved to be the best pollen source for pistachio cultivars.
