ABSTRACT

This study is conducted on the mycorrhizal diversity associated with the olive plant in order to study this association between the two partners and to discover different genres and to use them as biological control agents. Arbuscular mycorrhizal fungi are very important in the life of most herbaceous plants, fruit trees and some forest trees. In Algeria, the olive tree (Olea europea L.) represents a valuable economic potential for fruit tree cultivation. As a result, knowledge and exploitation of associated mycorrhizal fungi may be a tool for its sustainable development.
The aim of this study was to contribute to the study of symbiosis: mycorrhizal in the olive tree (Olea europea L.) of the Chemlal variety from the Bouhamdoune station Jijel. Algeria. Estimation of colonization by endomycorrhizal fungi revealed a high frequency of colonization recorded for spring 2016 (92.86%), relative intensity was (7.40%) and absolute with (15, 38%).

Key words: Olivier (Olea europea), Endomycorhize, Arbuscular mycorrhizal fungi, Chemlal, diversity.
