Mellel 2.75/24/2023 Studies such as the one performed by Zohary (1952) were hampered by the small sampling size, weak representation of the species, and unefficient methods. This disagreement is mainly because of little information being available on the phylogeny of the genus. Today, there are many questions about Zohary’s taxonomic treatment, the status of many of his species, and the accuracy of dividing the genus into four sections. The first complete classification of the genus was published by Zohary (1952). The species of the genus occur naturally from North Africa to the Philippines and from Texas to Nicaragura.įew systematic studies have been published on this important genus. The second comprises West and Central Asia. One comprises the Mediterranean region of Southern Europe, Northern Africa, and the Middle East. Two centers of diversity have been described. Pistacia is believed to have originated in Central Asia. Fruit a flattened asymmetrical drupe, embryo curved endosperm scanty or lacking. Nectariferous disk present, usually intrastaminal. Flowers are almost always unisexual, radial, small, with well developed staminodes or carpellodes, and apetalous sepals are usually 5, distinct to slightly connate stamens are 4 - 5, filaments are very short, usually glabrous, and usually distinct pollen grains tricolporate or triporate carpels are usually 3 and variously connate ovary superior, with only 1 fertile and well developed carpel gynoecium asymmetrical and unilocular with apical placentation, ovule 1 stigma capitate. Inflorescences are determinate and terminal or axillary. Leaves are alternate, deciduous or persistent, pinnately compound, but sometimes trifoliolate or unifoliolate, pari-or imparipinnate, membranaceous or leathery. Members of the genus are dioecious trees or shrubs with well-developed vertical resin canals. Currently, Iran, the United States, Turkey, and Syria are the main pistachio producers in the world, contributing over 90% of the world production. Pistachios have been reported as a remedy for scirrhus and sclerosis of the liver, abscesses, poor circulation, and other medical problems. The resin is used as a blood-clotting agent in Europe and the Middle East, while husks are used in India for dying and tanning. They also have traditional, medicinal, and non-food uses such as toothache relief. Pistachios are utilized mostly in the shell, for fresh consumption processed uses include candy, baked goods, and ice cream. It has edible seeds and considerable commercial importance. vera fruits has increased over the last two decades reaching an annual value of about $2 billion (harvested crop). (cultivated pistachio) is by far the most economically important species in the genus. It contains nine species and five subspecies according to the current study. belongs to the family Anacardiaceae (cashew family), order Sapindales. emarginata (Engl.) AL-Saghir is made, and the names P. A key to the 14 taxa that have been recognized by this study is included. The genus is divided into two sections: section Pistacia and section Lentiscella. It includes the following taxa: Pistacia atlantica Desf., P. The taxonomy of this genus is revised in detail through our research. The taxonomic relationships among its species are controversial and not well understood due to the fact that they have no genetic barriers. vera, which has edible seeds of considerable commercial importance whose value has increased over the last two decades reaching an annual value of about $2 billion (harvested crop). Pistacia is an economically important genus because it contains the pistachio crop, P.
