  Pistachio is a dioecious and cross-pollination species and suitable male genotypes is essential for its adequate fruit production. The quality of the produced nuts is also directly affected by pollen sources. In the present study, the female pistachio trees of Akbari commercial cultivar, in their ON-year cycle, were selected and hand-pollinated with three different pollen sources (T5, T17, T18) and compared to open-pollinated trees (T0). This research was undertaken as a completely randomized block design with three replications. Artificial pollination had a positive effect on the fruit set percentage. Furthermore, fruit fresh and dry weights, fruit dimensions, nut as well as kernel characteristics were affected corresponding to each pollen source. Though all 3 pollen sources had a positive effect on measured fruit characteristics, the effect of T17 was more prominent. Owing to xenia and metaxenia effects, longer nuts were observed following pollination with T5 pollen grains. Also, utilization of T17 pollen grains led to production of weightier fruits with higher splitting rate (93.33 % as compared to control, open pollinated trees (63.78%)). The results of the present study approved the imperative role of pollen source for pistachio fruit production. The results also recommended T17 genotype as a suitable pollinizer for Akbari pistachio cultivar. تفاصيل المقالة

  The objective of this experiment was evaluation of self-compatibility and identification, introduction and selection of late flowering genotypes as cultivars. This experiment was carried out in order to determine the best pollinator for two commercial almond cultivars, 'Shahrood 12' and 'Shahrood 21'. Applied pollinator cultivars were included pollen from 'Shahrood 21', 'Genco', 'Tuno', '5-15' and 'Super-nova' that were applied on 'Shahrood 21' mother trees, and 'Shahrood 12', 'FeilipCeo', 'Tuno', '5-15' and 'Super-nova'. Results showed no fruit formation in non-pollinated and self-pollinated flowers. Although, results from cross pollination using pollen from other cultivars showed higher fruit set using pollen of 'Genco' for 'Shahrood 21' , and '15-5' for 'Shahrood 12' cultivars. Samples were collected using pollinated flowers for further microscopic examinations. Field and microscopic examination of pollen tube growth in the style confirmed above results. The quantitative traits of fruits obtained of some known almond hybrids were assessed in order to evaluation of this phenomenon which known as xenia. The recorded traits were length (L), width (W), thickness (T) of fruits and seeds, and W/L and T/L ratios. تفاصيل المقالة

  The objective of this experiment was to evaluate self-compatibility of two late blooming almond cultivars and identification and introduction of suitable pollinizers from late flowering genotypes, and evaluation of pollen source effect on fruit characteristics to earn high quality nuts for Iranian almond industry. This experiment was carried out in order to determine the best pollinizer for two commercial almond cultivars, ‘Shahrood 12’ and ‘Shahrood 21’ (♀). pollen sources were ‘Shahrood 21’, ‘Genco’, ‘Tuno’, ‘5-15’ and ‘Supernova’ (♂) which were applied on ‘Sharood 21’ mother trees, and ‘Shahrood 12’, ‘Feilip Ceo’, ‘Tuno’, ‘5-15’ and ‘Super-nova’ (♂). The results showed no fruit formation in non-pollinated and self-pollinated flowers. However, the results from cross pollination using pollen from other cultivars showed higher fruit set using pollen of ‘Genco’ for ‘Shahrood 21’ , and ‘15-5’ for ‘Shahrood 12’ (♀) cultivars. The samples of pollinated flowers were collected for further microscopic examinations. In order to evaluate the effect of pollen sources, quantitative traits of nuts were measured. The recorded traits were length (L), width (W), thickness (T) of seeds, and W/L and T/L ratios. تفاصيل المقالة
