Optimizing Potato (Solanum tuberosum), Plant Transplantation through Micropropogation

Abstract

Aims: A pot experiment was set to identify the most effective symbiotic couples during the acclimatization of Solanum tuberosum vitroplants inoculated with arbuscular mycorrhizal fungi (AMF). Methodology: The answer to inoculation of 5 strains of MA fungi Funneliformis mosseae, Rhizophagus aggregatus, Rhizoglomus fasciculatum, Rhizoglomus intraradices, Rhizoglomus manihotis is evaluated on potato varieties Aïda, Atlas and Odessa. For each variety, the experimental device was totally randomized with 5 replicates. The experiment lasted 3 months. Results: The F. mosseae strain has the highest mycorrhizal dependencies with 81.51% and 70% respectively in the Atlas and Aïda varieties. Adessa is less than 40% dependent on all strains of fungi tested. In the Atlas variety, the F. mosseae strain significantly stimulates the aerial biomass of the plants, which reaches 723.32 mg compared to the other mycorrhizal and control strains. The production of minitubers was stimulated by mycorrhizal fungi. In the Aïda variety, the two strains F. mosseae and R. aggregatum averaged 2.80 and 2.72 minitubers per plant, respectively. With the Atlas variety, F. mosseae and R. intraradices result in the most significant production of minitubers. Conclusion: The different species of fungi tested do not have the same level of efficiency towards these varieties. Nevertheless, they all promote plant development and potato production compared to non-ininoculated controls. Mycorrhizal dependence is more observed with both Atlas and Aïda varieties.
