    The Plant Growth Promoting Activities of Actinomycetes
    (October University for Modern Sciences and Arts, 2020) Kamal Kamel, Mirna
    The relationship between the plant and rhizosphere microorganisms divides into either positive interaction or negative interaction, depends on how the rhizosphere microorganism affect the plant, the majority of many plants are under the danger of phytopathogens that affect plant growth and productivity. The goal of this study was to create a commercial bio-control agent composed of rhizosphere Actinomycetes ready to enhance the expansion of plants and enhance the plant defence system whereas additionally having the ability to survive within the rhizosphere. During this study, 19 bacterial strains of Actinomycetes were obtained (AC1, AC2, AC4, AC6, AC14, AC15, AC18, AC20, AC22, AC24, AC25, AC26, AC28, AC34, AC40, AC51, AC52, AC73, AC61/2B), to determine which strains have the highest effect on enhancing the plant growth, but only 7 strains showed significant effect on plant growth as (AC2, AC14, AC18, AC22, AC25, AC28, AC40). Among them strains (AC25, 40, 26, 51, 18, 14, 34) showed significant antifungal activity against Fusarium oxysporum during the dual culture assay. The greenhouse experiment indicated that Actinomycetes treated wheat plants had shown good growth parameters such as root and shoot length and weight compared to non-inoculated control plants.
