Akbari, Super Long
Akbari pistachios is One of the commercial cultivars of pistachio which has high economical value.
Pistachio dealers call that Abdollahi, and abdollahi a local grafter discovered in Fakhr Abad Khashkooyeh village in Rafsanjan.
Morphological properties of Akbari pistachios:
The fruit almond-shape, elongate and coarse Features of this cultivar include spray clustering.
high yield, uniformity of crop ripening, high and strong growth, density and high leaf area.
Due to its high vegetative growth, this cultivar is suitable for areas with severe sun, hot summers and sunburn.
It is slow terms of flowering, and flowers grow from April 20 to 31.
The leaves of this cultivar, like other late-flowering cultivars, grow before the flowers and in this cultivar.
it is about 4 to 5 days earlier.
The growth of the nut of this cultivar starts from 10 to 20 of July and lasts until the end of August, which is about 39 to 45 days.
Akbari pistachios farmers harvest in late September and is one of the late cultivars in terms of ripening.
Quantitative and qualitative characteristics of Akbari pistachios:
The average dry yield of 12- to 16-year-old trees in Rafsanjan conditions is 1311 grams per tree.
The number of seeds per ounce is 21 to 22 seeds, the amount of pistachio openings is 12 to 13 percent and blank fruits (fruits without nut) is 3.11%.
From every 100 grams of dried fruit (nut with shell) 55 to 54 grams of nut is available. The protein content of the nut is 6.19% and its fat content is 2.53%. In terms of biennial bearing, it is average.
It is important that ounce traits, percentage of open fruits and percentage of blank fruits, as well as the percentage of protein and fat in the nut, can 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 be variable by the timing of harvest, and delays in harvest increase the fat percentage and reduce the protein percentage in the nut.
Due to late flowering, spring cold usually damage pistachios, but during flowering, it face to a lack of pollen and the end of flowering of male trees and it is possible that a large percentage of inoculated flowers shed or become blank fruits (Parthenocarpy).
In order to solve this problem, late-flowering male cultivars use or transplanting male cultivars on a seedbed or between Akbari rootstocks is useful and effective as well.
To solve the problem of existing gardens and orchards, artificial pollination of this cultivar scientists recommend for 1 to 2 times in the whole flower stage.
Also, due to the late-flowering of this cultivar, if there is early heat in late April, damage to the flowers and even the newly fruits.
