BARRERA-VIOLETH, José Luis; OVIEDO-ZUMAQUE, Luis Eliécer  e  BARRAZA-ALVAREZ, Fernando Vicente. Evaluation of native mycorrhizae in plantain crop (Musa AAB Simmonds) in nursery phase. Acta Agron. [online]. 2012, vol.61, n.4, pp.315-324. ISSN 0120-2812.

The objective was to evaluate the effect of three vesicular arbuscular Mycorrhizal native genera application on growth of Hartón plantain plants in nursery stage. The strains were obtained at Universidad de Córdoba from the Plant Pathology Laboratory collection, which were isolated from plantain crops in Lorica, Los Córdobas and San Bernardo del Viento. A completely randomized experimental design with six treatments (T) was used: Glomus sp. (T1), Acaullospora sp. (T2), Scutellospora sp. (T3), a genera combination of Glomus, Acaullospora and Scutellospora (T4), a chemical treatment (diammonium phosphate, DAP, T5) and absolute control (T6), with ten replicates per treatment. Results showed that more spores obtained and larger infection percentage with the combination of mycorrhizae genera (T4), followed by T1, T3 and T2 treatments. Besides the above, with the combination of mycorrhizal genera, they were obtained significant difference compared with other treatments in regard to pseudostem diameter, leaf area ratio:fresh and dry weight of root. Regarding to leaf area and root length, T5 treatment showed the higher measurements.
