The objective of this work was to assess the effect of two arbuscular mycorrhizal fungi (AMF) at different phosphorus
concentrations on survival and growth of pineapple (Ananas comosus (L.) Merr.) plantlets obtained for micropropagation.
Plantlets were multiplied for in vitro cultures and were acclimatized under three sequential steps. The effects of AMF and
phosphorus were not significant on plantlet survival and plantlet height, however Glomus claroideum stimulated that the
plantlets were with higher leaves number and dry weight. The results demonstrated that plantlet growth was maximized
with G. claroideum and phosphorus 0.9 mM.
