“…Inocula of AMF produced on farm had been shown to have positive yield effects on vegetable plants such as potatoes and peppers (Douds et al 2007;Douds et al 2012), cassava (Sieverding 1991), and coriander, fenugreek and carrot (Gaur et al 2000) under field conditions. AMF inoculum used in this study was produced in a sugarcane bagasse, carbonized rice shell and sand mixture with pre colonized grain sorghum plants to yield 283 to 350 AMF propagules cm -3 (Schlemper & Stürmer 2014).…”

“…Methods for the on-farm production of AMF inoculant utilize large plastic bags (Douds et al 2010) or raised beds (Sieverding 1991), with soil-based or composted substrates mixed with vermiculite, perlite or peat (Gaur et al 2000;Douds et al 2010) and grasses usually as host plants to multiply the fungi (Douds et al 2010;Sieverding 1991). Application of on-farm mycorrhizal fungus inoculant improved fruit production of pepper (Douds et al 2012), potatoes (Douds et al 2007) and phosphorus content in cassava (Sieverding 1991).…”

Mycorrhizal fungus inoculum produced on-farm can be used during production of woody plant seedlings to reduce costs associated with purchase of commercial inoculant and fertilization. This study aimed to test the efficiency of a mycorrhizal inoculant produced on-farm to promote growth and nutrition of woody species in combination with different levels of phosphorus. Plants were submitted to different treatments of phosphorus (0, 40 and 80 mg P/dm 3 ) and mycorrhizal inoculation (uninoculated, and inoculation with Rhizophagus clarus [Rc] or Claroideoglomus etunicatum [Ce]). Species included were Luehea divaricata, Centrolobium robustum, Schinus terebinthifolius, Garcinia gardneriana, Cedrella fissilis, and Lafoensia pacari. The inoculum was produced using the on-farm methodology. Mycorrhizal colonization of plants inoculated with Rc and Ce ranged from 44.8 to 74.8%, except for Garcinia gardneriana. Inoculation treatment increased plant height and stem diameter of Luehea divaricata, Centrolobium robustum and Cedrella fissilis while phosphorus, inoculation and the interaction affected these parameters for G. gardneriana and Lafoensia pacari. Shoot biomass increased significantly with inoculation treatment in four species. For most species, mycorrhizal fungus inoculation and the addition of phosphorus increased the shoot phosphorus content. Mycorrhizal fungus inoculum produced onfarm successfully colonized tree seedlings and improved growth and/or nutrition under nursery conditions, producing seedlings useful for revegetation of degraded lands.

“…The uptake of non-mobile nutrients such as P is the main benefit to plants promoted by the fungi, resulting in higher growth rates and improved nutrition; on the other hand, fungi receive carbohydrates translocated from above-ground parts to roots for their growth and sporulation (Smith & Read, 2008). Mycorrhization of plant seedlings generally results in a faster development, higher yields and greater tolerance to environmental stresses at field transplanting (Douds et al, 2007;Hu et al, 2009;Higo et al, 2010;Pellegrino et al, 2011), but this microbial resource has rarely been tested for tropical palm species.…”

SUMMARYInoculation with arbuscular mycorrhizal fungi (AMF) of tree seedlings in the nursery is a biotechnological strategy to improve growth, survival after transplanting, biomass production and to reduce the use of fertilizers. Archontophoenix alexandrae and Euterpe edulis are palm species used in southern Brazil to produce the palm heart, the latter being included in the list of threatened species due to the overexploitation of its native population. The purpose of this paper was to evaluate the effect of mycorrhizal inoculation on growth and physiological parameters of A. alexandrae and E. edulis. After germination, the seedlings were inoculated (AMF) or not (CTL) with AMF in the treatments. Values of chlorophyll content, biomass and shoot phosphorus were not statistically different between the AMF and CTL treatments, after five months in the greenhouse. Inoculation with AMF significantly increased the levels of starch and soluble carbohydrates in shoots and roots of both species. Under field conditions, AMF had no effect on stem diameter and height after 12 and 24 months, but total plant biomass and leaf, stem and root biomass were greater in AMF than in CTL plants. The data indicated that AMF inoculation in the nursery

“…En general, los porcentajes fueron bajos, en comparación con otros cultivos tradicionales como los cereales (Montaño et al, 2001), aun cuando el tiempo (noviembremayo) fue suficiente para el establecimiento de una colonización mayor. La alta fertilización química aplicada al cultivo de papa podría explicar esta baja micorrización de las raíces; sin embargo, estos porcentajes fueron superiores a los informados por Cesaro et al (2008) en agroecosistemas cultivados con papa en Italia, que fluctuaron entre 2,1 y 5,5% y de los encontrados por Douds et al (2007) en un ensayo en campo con S. tuberosum cv. "Superior", donde la colonización alcanzó valores entre 11 y 14%.…”

“…Un grupo de microorganismos benéficos son los hongos micorrícicos arbusculares (HMA), biótrofos obligados, que forman asociaciones mutualísticas con un amplio rango de plantas hospederas, incluyendo importantes cultivos de interés agrícola (Preger et al, 2007). En los sistemas de agricultura sustentable el manejo de los HMA como biofertilizantes reduce o elimina el uso de fertilizantes tradicionales mejorando la productividad de los cultivos (Douds et al, 2007). Sin embargo, las prácticas de manejo agrícola pueden afectar la composición y diversidad de las comunidades HMA (Mathimaran et al, 2007) causando un efecto negativo en la asociación simbiótica (Gosling et al, 2006).…”

RESUMENLos efectos negativos causados por los fertilizantes químicos al medio ambiente han conducido en los últimos años a la investigación de alternativas ecológicas para el manejo de los cultivos, como los biofertilizantes, que utilizan microorganismos fijadores de nitrógeno (N). Durante la temporada 2013-2014 se estableció un ensayo de campo en la Estación Experimental Pillanlelbún, que tuvo como objetivo evaluar el efecto del biofertilizante Twin-N sobre los hongos micorrícicos arbusculares (HMA) nativos en un cultivo de papa, variedad Desireé. Twin-N contiene bacterias del género Azospirillum en concentración de 1×10 11 UFC g -1 pc. Se utilizó un diseño experimental de bloques completamente al azar con tres tratamientos y cuatro repeticiones. Los tratamientos correspondieron a: T0: un control con fertilización química a la siembra, FQS; T1 = FQS + 50 kg de N ha -1 (aporca) y T2 = FQS + 1 L Twin-N ha -1 (floración). A la cosecha se cuantificaron parámetros fúngicos y número, rendimiento y condición sanitaria de los tubérculos. En relación con los parámetros HMA, el tratamiento con Twin-N presentó la menor colonización fúngica en las raíces y una baja cantidad de esporas en la rizósfera, acompañado de un significativo incremento en el rendimiento de los tubér-culos, señalando que los microorganismos contenidos en el biofertilizante contribuyeron a mejorar la efectividad de los hongos nativos. La incidencia de enfermedades en los tubérculos fue baja, solo se encontraron diferencias en la pudrición seca y cráteres. Se concluye que la adición del biofertilizante Twin-N a un cultivo de papa podría reemplazar en parte la fertilización química nitrogenada disminuyendo los problemas de toxicidad en el suelo.Palabras clave: hongos micorrícicos arbusculares, calibre del tubérculo, biofertilizantes, sarna en papas.
