CONTRIBUTION A L'EVALUATION DE LA MICROFLORE FONGIQUE DU SOL DANS QUELQUES STATIONS DE LA REGION DE BISKRA

Abstract

We proceeded to an bio-physico-chemical study on the micromycèts of the arid soil, the important factors of the fertilization of the telluric biotope, in four stations of the region of Biskra (M'ziraa-soil cultivates by the truck farming, Biskra-cultivated soil by cereal, Tolga-old-palm trees, Doucen-youg palm trees), thanks to two takings (in December and April) in court of the period 2014-2015. Statistical analyses of the data collected by means of an ACP, for this period showed that the station of Tolga is dominated in winter by the genus of yeasts Rhodotorulasp (halophilous and hygrophilous), as well as by the genus of micromycèts Aspergilus sp (halophilous and xérophilous), these two genus are adapted to the arid soils and they are endemic into the region of Biskra,
