Identification of the best fruit collection height for the restoration of wild pistachio in Golestan province

In the Northeastern of Golestan province (Maraveh Tappeh city), the wild pistachio species (P. atlantica) due to unconventional usage is on the slope of extinction and destruction, so the restoration of this species is truly essential. The fruit was collected separately from 11 trees in two range of altitudes (below and above 011 meters above sea level), quantitative traits (healthy and empty) and qualitative traits (length, width, and depth) of seeds were measured and recorded. Quantitative Data Analysis shows a significant difference between the two altitude ranges, so that trees located below 011 meters, produce more healthy fruit and less empty ones. In the two altitudes, the fruit didn’t show any significant differences in terms of length, width and depth, also in weight (with fleshy and wooden shell), significant differences could be absorbed. Finally, the weight of fleshy and wooden shell and the fruit kernel were compared and results showed that the main cause of these significant differences was the fruit kernel. The findings of this study showed that for the restoration of wild pistachio, the fruit should be collected from trees at an altitude of 011 meter above sea level upwards so that the chance of production and establishment of seedling increases.
