Influencia de los hongos micorrizicos arbusculares sobre el crecimiento de vitro plantulas de piña (ananas comosus (l.) merr.) con diferentes niveles de fosforo

Abstract

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.
