| The traditional method of propagating Etlingera elatior (Jack) R.M. Sm. promotes the proliferation of pathogens, reducing the quality of its output. However, as an alternative, one can use in vitro culture, making it possible to obtain plants free of pathogens on a large scale. Moreover, inoculation of plants with arbuscular mycorrhizal fungi (AMF) can be critical to ensure greater survival and development of these plants under ex vitro conditions. Thus, the present study examined the effect of AMF inoculation (Gigaspora albida and Claroideoglomus etunicatum) on success in the establishment and development of E. elatior on the acclimatization phase. Plants were inoculated with G. albida, C. etunicatum or MIX (both AMF isolates) and after cultivation in a... |

| The objective of this work was to assess the potential of three isolates of arbuscular mycorrhizal fungi to promote growth of micropropagated plantlets of Tapeinochilos ananassae during acclimatization. The experiment was carried out in greenhouse, in a completely randomized block design, with four inoculation treatments: non-inoculated control and plants inoculated with Glomus etunicatum, Acaulospora longula or Gigaspora albida, with ten replicates. After 90 days, the following parameters were evaluated: survival rate, height, leaf and tiller number, leaf area, fresh and dry biomass, contents of macro- and micronutrients in the root and shoot, glomerospore number, and mycorrhizal colonization. The survival percentage was 100%, except for plants inoculated... |

| Fungos micorrízicos arbusculares em solos salinizados e adjacentes no Vale do Submédio São Francisco, Brasil). Visando ampliar os conhecimentos sobre FMA em áreas salinizadas, foram coletadas 23 amostras de solo na rizosfera de 15 hospedeiros, em quatro áreas, caracterizadas por níveis crescentes de salinidade: áreas I (0,08-0,45 dS m -1), II (1,03-6,38 dS m -1) e IV (4,97-19,86 dS m -1), com Latossolo Amarelo, estão incluidas no Projeto de Irrigação Bebedouro (Petrolina, Pernambuco), enquanto área III (3,18-10,91 dS m -1), com Vertissolo, está no Projeto de Irrigação Mandacaru (Juazeiro, Bahia). A densidade de esporos de FMA no campo variou de 0,31 a 8,06 esporos g -1 de solo: o primeiro ciclo de multiplicação favoreceu a esporuralçaõ, que decresceu a... |

| The effect of arbuscular mycorrhizal fungi (AMF) on micropropagated banana plantlets was evaluated during the acclimatization period. Plants were inoculated with Acaulospora scrobiculata, Glomus clarum or Glomus etunicatum. After cultivation in a greenhouse for 3 months, height, leaf area, fresh weight and dry matter of root and shoots, level of AMF colonization, nutrient level, photosynthesis and transpiration rate, water potential and stomatal conductance were measured. The number of AMF spores produceded in each treatment was also determined. Plantlets inoculated with Amf had greater height, leaf area and fresh weight of shoots and roots, as well as higher rates of photosynthesis and transpiration than controls. Plants inoculated with Glomus were... |
