  abstract = {{T}he pawpaw ({C}arica papaya {L}.) is a very productive fruit tree but is not widely exploited on the international market due to rapid deterioration of the fruits after harvest. {T}his deterioration is due to a nutritional dysfunction related to the deficiency of nutrients, especially calcium, which is involved in the firmness of fruits in general and the papaya in particular. {T}he symbiotic capacity of arbuscular mycorrhizal fungi ({AMF}) has been profiled to enhance uptake and regulation of exchangeable calcium ions in the soil. {T}he aim of this study was to reduce losses and improve post-harvest quality of papaya fruits through the potential of arbuscular mycorrhizal fungi ({AMF}) in calcium uptake for international exploitation. {A} composite of {AMF} species identified of papaya rhizosphere in two study sites, combined with different calcium doses (0 µ{M}, 100 µ{M}, 200 µ{M}, 300 µ{M} and 1000 µ{M}) was applied to two papaya varieties (calcium deficiency-resistant {V}1 {C}alina papaya {IPB}9 and calcium deficiency-sensitive {V}2 {S}olo {N}°8) and the effect was evaluated in greenhouse. {T}he frequency and intensity of root colonization were evaluated. {T}he {AMF}/calcium 1000 µ{M} combination significantly influenced ({P} = .05) the number of plant height (44%, 68%), leaves (71%; 122%), fresh biomass of leaves (3,3%; 596.3%), roots (159.2%, 265.3%), and stems (910%;4075%) in both varieties {V}1 and {V}2 respectively compared to {AMF}/ calcium 0 µ{M}. {I}ncreased absorption of calcium ions (150%) and phytochemicals were recorded in the leaves. {T}he frequency (81%; 85%) and intensity (15%; 21%) of root colonization by {AMF} respectively was not significantly different ({P}>.05) in both two varieties ({V}1 and {V}2). {H}owever, the presence of {AMF} spores was observed on the roots of papaya plants mycorrhized with the calcium 1000 µ{M}. {I}noculation with {AMF} combined with the high calcium dose (1000 µ{M}) promoted mycorrhizal infectivity of roots, colonization of mycorrhizal spores in the soil and increased roots absorption surface area.},
