Date palm trees in southwest Tunisia:
Date palm is the basic tree of the oasis system; it represents the core of the oasis agro system. It is characterized by a pseudo trunk called stipe, it can reach 30 to 40 m in height. The date palm tree is a heterozygous and dioecious species, there are both male and female palms. In order to get successful pollination, male and female date palm trees must be in close proximity. Natural pollination by wind is then only possible when the number of male individuals in an oasis is very large, which is not the case in the oasis of Tunisia. Farmers seek to obtain a high density of fruit-producing females, while the number of male plants in an oasis varies between 2 and 6. Therefore, natural pollination must be replaced by artificial pollination, done by the farmers. The Tunisian oasis is rich in plant diversity in date palms. In the Tunisian continental oasis, more than 200 cultivars exist, the main ones are Deglat Nour, Alig, Kenta, Akhouet, etc…
The Tunisian oasis contains more than 3,500,000 feet of various varieties with the predominance of the variety “Deglet Nour“. This variety constitutes the mainstay of the oasis economy and contributes significantly to the trade balance through exports. Kébili region in “Nefzaoua” contains more than 3 million date palms, about 58% of national production, followed by Tozeur region (Djérid) with 31%. These two sets account for approximately 90% of the date palm heritage of the Tunisian oasis.
