Ecophysiology, quality, and mycorrhizal dependency in Musa spp. (cv. Grand naine) seedlings

Abstract The use of alternative technologies involving biological processes, with economic and ecological gains, is desirable for both the expansion Musa spp. farming renovation areas low yields. Arbuscular mycorrhizal fungi (AMF) can stimulate plant growth, especially by increasing absorption phosphorus (P) other nutrients. This study analyzes influence AMF on growth physiology micropropagated Musaspp. plants submitted to doses P. experimental design was randomized blocks, in a 5 x factorial arrangement, which factors were inoculation (Glomus clarum, Gigaspora margarita, , albida,Clareoideoglomus etunicatum, control without AMF) five P (0, 50, 100, 200, 400 mg kg-1), four replicates. application increased seedlings, regardless inoculation. highest rates colonization occurred at lowest doses, dose 50 kg-1 provided better conditions formation all species under study. symbioses AMF, as well P, photosynthesis rate, thus favoring development, quality seedlings. Species G. C. margarita most promising growth.
