ABSTRACT
Introduction: Arbuscular mycorrhizal fungi form common and widespread associations with 80 % of terrestrial plants. Mycorrhizae are beneficial for plants and environment, especially in arid and semi-arid areas. Mycorrhization varies depending on plants and fungi. Objective: The aim of this work is to assess the impact of mycorrhization on the productivity of four African varieties of sesame (Sesamum indicum L.) under controlled conditions. Methods: The effect of Gigaspora rosea and Rhizophagus intraradices inoculation on four African sesame varieties (AS09, AS14, AS15 and AS25) was evaluated in the greenhouse. Results: The experimental system consists of randomized blocks with two factors and three repetitions. The results showed that, on sterile soil without inoculation there is no mycorrhization. The frequency of mycorrhization is greater than 80 % for inoculated plants, it is 100 % with Gigaspora rosea. The intensity of mycorrhization for R. intraradices is less than 50 % but greater than this value with G. rosea. Mycorrhization increased the mass yield of seeds per plant. Conclusion: Mycorrhization is more significant with G. rosea which has led to an increase in the number of seeds per capsule for the sesame varieties AS09, AS14 and AS15. Yield and mycorrhizal parameters are related to mycorrhizal fungi and sesame varieties. G. rosea forms the best symbiotic couple with the four varieties of sesame (Sesamum indicum L.).
Key words: Sesamum indicum L., yield, Gigaspora rosea, Rhizophagus intraradices
