in Iran, which, despite its not so long history, is significantly expanding.

Morphological properties of Ahmad Aghaei Pistachio:

The fruit is almond-shape but the appearance is similar to the Kaleh Ghouchi cultivar.

The redness of the nut, the whiteness of the shell and the large size of the fruit cause its expansion.

Phenological properties of Ahmad Aghaei Pistachio:

 In terms of flowering its medium and in Rafsanjan conditions, the flowering will occur from 13 to 25 of April. The leaves of this cultivar begin to grow about 2 to 3 days before flowering.

Rapid nut growth begins on July 10 to 20 and complete by the end of August, which is about 39 to 45 days.

This cultivar harvests in the third decade of September and in this regard, it is one of the cultivars with slow ripening speed.

It is vulnerable to shedding during ripening and will get separate from the tail of the fruit and shed due to wind and bird attacks.

Mixing the product which has fallen with the healthy product will increase the chance of fungal infections.

Quantitative and qualitative characteristics:

The average dry yield of 12- to 16-year-old trees in Rafsanjan conditions is 3066 grams per tree.

The number of seeds per ounce is 24 to 26 seeds, the amount of openings is 6 to 7 percent and the amount of blank fruits is 7 to 8 percent.

From every 100 grams of dried fruit, 56 to 57 grams of nut.

The protein content of the nut is 15 to 16% and its fat content is 58 to 59%. Despite the very desirable features of this cultivar.

it is relatively extreme In terms of biennial bearing, which will cause the amount of harvest to vary each year.

This problem can control through proper management (especially in terms of pruning).

ounce traits, percentage of open fruits and percentage of blank fruits, as well as the percentage of protein and fat in the nut

matters change under the influence of garden management (irrigation, nutrition, pest control and pollination) and to some extent, environmental conditions.

The fat and protein percentage can also base on the timing of harvest.

delays in harvest increase the fat percentage and reduce the protein percentage in the nut.
