    ABSTRACT
    The study on plant parasitic nematodes (Pratylenchoides Winslow, 1958, Ditylenchus Filipjev, 1936 and Longidorus Micoletzky, 1922) infecting durum wheat (Triticum durum Desf.) like a waha variety in the pilot farm of Si Achour (Medea) revealed that three taxa of phytoparasite nematodes belong to two orders (Tylenchida and Dorylaimida). The degree of infestation by these parasites varies from plot to plot and within the same plot. Variation in infestation is the result of several factors related to the growing system and environmental conditions. The study was conducted in two fields of durum wheat that have different textures throughout the vegetative cycle. The objective was to study the dynamics and density of nematodes under the influence of a few various physical-chemical factors. Besides, nematodes’ soil and root were extracted respectively by the Cobb (1918) method (so-called “bucket” method) and the Baermann (1917) method that are modified using Coyne et al. (2010). At both experimental sites, 3 species of phytoparasitic nematodes were recorded during the maturation stage. These species include Pratylenchoides sp., Ditylenchus sp., Longidorus sp. and some saprophagous nematodes. Among them, Ditylenchus sp. and saprophagenenes represent the vast majority of individuals found in the soil. Alternatively, durum root nematodes are represented mainly by two species: Pratylenccoides sp. and Ditylenchus sp.

    ASBTRACT
    This work was carried out at the Dahra forest in the north-west of the wilaya of Chlef in western Algeria, to give the state of the vegetation cover and in particular that of the groups to Tetraclinis articulata (Vahl) Mast. (Pinales Cupressaceae) currently existing in this region. The floristic inventory includes more than 74 taxa, divided into 32 families, that belong to the Mediterranean biogeographic type with a percentage of 48%, next to the high rate of taxa of the whole Mediterranean develop endemic species and Eurasian elements. From the biological point of view chamephytes have an important place in the plant groups in Thuya followed by Therophytes, Phanerophytes, Hemicryptophytes and Geophysicists. Herbaceous plants are the most dominant with a percentage of 68%, followed by perennials with 32%. We were also able to describe a list of the so-called faithful species of Tetraclinis articulata or the species that make up the groups of the latter.

    Diagnosis of the floristic diversity in south of Saida (west Algerian steppe)
    https://doi.org/10.31396/Biodiv.Jour.2021.12.2.319.323

    ABSTRACT
    This work allowed to make an assessment of the floristic diversity in south of Saida, in western Algeria, based on the phytoecological aspect, biological, morphological and biogeogaphical of this heritage. Given the nature of the problem to be addressed, we used the Zuricho Montpelieraine according to the Braun-Blanquet method: we harvested all plant species encountered, listed the species on a surface plot (area minimum), and registered the floristic surveys. The floristic diversity is relatively low compared to other oranaises areas in Algeria, it is closely linked to the severe climatic conditions coupled with a strong anthropozoic action which translates by the preponderance of species such as: Artemisia herba-alba Asso, Atriplex halimus L., Peganum harmala L., Salsola vermiculata L. Currently the conservation of different taxa are scientific priorities for assessment and management of this biological heritage.
