This study aimed to evaluate arbuscular mycorrhizal fungi (Glomus cubense) functional viability and colonization ability in liquid medium. Two experiments were conducted, one studied spores fungal viability in liquid medium and sterile water was used in control around six months. Average 100 spores were used. In second text, we studied spores ability colonizing stored by six months in sorghum (Sorghum vulgare Perz.) plants. Mycorrhizal performance indicators were determined (colonization frequency and intensity and protein total) and plants growth and development indicators (dry mass root of air). Data were analyzed using Statgraphics Centurion for Windows and used the Duncan test with a significance of 5% in the cases where the ANOVA was significant. Results showed Glomus cubense spores viability after six months, with marked loss of viability in the variant preserved in sterile distilled water. Colonization studies demonstrated spores functional stability on sorghum plants, due to were achieved superior colonization levels in plants inoculated with respect to non-inoculated. Results demonstrated viability and functional stability of liquid inoculant retained up to six months
