Les Trichoderma sont des champignons imparfaits saprophytes que l’on retrouve dans divers milieux comme le sol, le bois mort, les debris des vegetaux et les organes aeriens des plantes. Ils ont un role phytoprotecteur et stimulateur du developpement des plantes associees. L’effet de differents facteurs abiotiques (temperature, pH, salinite) sur la croissance mycelienne de trois souches locales de Trichoderma a ete evalue. Ces souches ont ete isolees a partir de la rhizosphere de la tomate. Une etude preliminaire a ete effectuee sur quatre milieux de culture (PDA, MEA, SB et DOX) pour la selection du milieu d’etude. Les resultats obtenus montrent que le milieu PDA permet une meilleure croissance des souches de Trichoderma . La temperature optimale de croissance des differentes souches est de 29 °C et le pH 5 se revele etre le plus adequat pour la culture des Trichoderma . Cette etude montre egalement que les souches de Trichoderma resistent a des concentrations de sel (NaCl) allant jusqu’a 3%. © 2016 International Formulae Group. All rights reserved.

English Abstract Trichoderma are saprophytic imperfect fungi that are found in various environments such as soil, dead wood, vegetable fragments and plant aerial organs. They protect and stimulate development of related plants. Effects of various abiotic factors (temperature, pH, salinity) on mycelium growth of three local Trichoderma  strains were investigated. These strains were isolated from tomato rhizosphere. A preliminary study was performed on four culture media (PDA, MEA, SB and DOX) for the selection of the best media. The results  showed that PDA medium was highly growth of Trichoderma strains. The optimum temperature for growth of different strains is 29 °C and pH 5 was found to be most suitable for Trichoderma culture. Indeed, Trichoderma strains resistant to salt concentrations (NaCl) up to 3%. © 2016 International Formulae Group. All rights reserved.
