Index. décimale : 570 Sciences de la vie. Biologie Résumé : The study of the genetic diversity of the date palm of the Oasis of Bou-Saâda led us to make
an inventory of palm trees in the four zones Djenane Btom, Djenane Nakhara, Dejnane
Hmaïd, and Djenane khachbat mimoum, Twenty-three varieties without count Dokkar and
the total number of palm trees is 2147. With the study of the morphological characteristics
(length of palm, number of spines ...) it was possible to describe and identify the twenty three
varieties listed, Varieties that exist only at the Oasis of Bou-Saâda as Bou-Saâdiya, Nebgaya
and Zebla.
Molecular identification of the date palm cultivars of the Bou-Saâda palm grove by the two
techniques ISSR (21 primers) and RAPD (27 primers) were used revealed an important
genetic polymorphism inter accessions is explained by the morphological difference between
the varieties. The RAPD and ISSR markers allowed to characterize and distinguish the
different cultivars. Analysis of the RAPD, ISSR data generated a phylogeny similar to that
revealed by RAPD
Concerning the genetic identification of Bayoud-resistant cultivars The use of the two R and S
plasmids as molecular markers will be effective in detecting the Bayoud-resistant cultivars.
Resistant cultivars have been identified from the cultivars tested. It has been found that Baâret
ljmal is resistant, on the other hand, the cultivar Deglet Nour represents the two plasmid forms
R and S. Thus, using this technique, it is possible to establish a list of cultivars of Algerian
date palm Resistant or sensitive to Bayoud
The Oasis of Bou-Saâda still retains an important genetic heritage, which must be protected
and used

Pollinisation is one of the most important phases in date's life time. Though, there are a lot of female palm trees and a small number of male palms, the pollinisation on process remains sufficient for all. And the most important thing is to do different studies before the pollinisation process. Thus, the essential research in this dissertation are montioned below:
The morphological study of the quantity and quality of male and female palm. The morphological study and the micrometrical study of spath and pollen grains: The results showed a distinct difference between male palm in many features and they differ from one to another.
Set percentage: during the study it has been viewed that there is a big influence of cultivars; That is to say, there is receptivity between pestilate and pollen grain. So the percentage of the set is affected by pollen by compatibility or non-compatibility with female bud.
The physical characteristics of dates: The results showed that the different sources of pollen grain have high significant difference and it gave us a semi stable diameters in both seasons even though there was unstable compatibility between the cultivars and elite males.
Identifying the chemical component of the seven studied cultivars: the fruits dates has affected by pollens and gave us different percentages in chemical components because the difference in pollen and therefore, this helps us in knowing the kind of pollen grains which has the best product with a particular cultivars. Contrary to which has a certain percentage of fiber and sucrose didn't affect by the pollen grains. On the base of this research we con clued that this study has gave a concerning jump in the production of dates by quality and quantity. Good manipulation of the natural and chemical characteristics of dates, we must control the process of pollination by determining the kind of pollen for each female cultivars.Diplôme : Doctorat En ligne : ../theses/biologie/ADJE4116.pdf Format de la ressource électronique : Permalink : https://bu.umc.edu.dz/md/index.php?lvl=notice_display&id=10215 دراسة مقارنة لتأثير حبوب لقاح نخيل التمر (الذكرية على صفات ثمارPhoenix dactylifera L.) بعض الأصناف الأنثوية [texte imprimé] / عيسى جروني, Auteur ; مبارك باقة, Directeur de thèse . - [S.l.] : جامعة الإخوة منتوري قسنطينة, 2016 . - 115 ورقة. ; 30 سم.

Palmier dattier caractérisation morphologique diversité variétale répartition adaptation Ziban Palm date morphological characterization varietal diversity distribution Index. décimale : 570 بيولوجيا Résumé : This work was carried out on 89 autochthonous varieties of date palm (Phoenix
dactylifera L.) in the oasis of the Zibans region (Biskra) for three consecutive years (2010 to
2012) and was dedicated to the study of the most distinctive varieties in term of phenotypic
criterion. Trough some statistical tools (PCA and FAC), we identified the discriminating
characteristics and / or similar between the different genotypes. Particular attention was paid to
the presence, location and distribution of these varieties in the vast region of Ziban related to the
environment of this area.
The results showed an efficiency of the morphological characters (quantitative and
qualitative) of fruits and leaves by highlighting the differences and similarities in genetic
patrimony.
A very large varietal diversity was found in the oasis of Sidi Okba and Tolga, almost all
of that phytogenetic potential is in adequacy with the specific bioclimatic conditions of the
region.
