“…Substrate enrichment with arbuscular mycorrhizal fungi (AMF) and hydrogel (T2): this treatment was prepared as T1 and we added 500 g of soil enriched with AMF. This substrate was produced in a greenhouse seeding a highly mycorrhizal host plant ( Medicago sativa L.) in rhizosphere soil (Becerra & Cabello 2007) collected from below adult plants of L. divaricata (Fig. 2C & 2D).…”

In a context of global desertification, direct seeding of native species is emerging as a hopeful technique to achieve large‐scale arid land restoration. Although low percentages of establishment have been reported for direct seeding in arid lands, it has been more cost‐effective than outplantings for some species. Therefore, in order to determine the most suitable species for direct seeding we evaluated potential germination in laboratory trials (ex situ), and seedling emergence and establishment in the field (in situ) for five shrub species from the most arid region of Argentina called “Monte.” Direct seeding was performed in three alternative environmental conditions: (1) abandoned oil‐drilling platforms, (2) bare soil patches, and (3) under the canopy of shrubs patches in cattle ranching areas. In the three cases, four soil treatments were applied: hydrogel, soil enrichment with arbuscular mycorrhizal fungi, and clay pot irrigation. Seedling emergence and establishment after the first period of extreme weather conditions (summer) were higher in severely degraded sites (oil‐drilling platforms). In this particular condition, seedling emergence and establishment presented the highest values for Ephedra ochreata (64.8–82.8% and 26.8–46.4%, respectively) and the lowest values for Larrea divaricata (6.78–24.8% and 2.8–6.4%, respectively). These results show that direct seeding offers potential possibilities to restart processes of assisted succession in arid lands and that species selection is a key stage/phase in direct seeding success.

“…The mean arbuscule richness (A) also varied and was the lowest in all Amaranthaceae, in particular, A. halimus (1.04%) and highest in D. viscosa (57.9%) (Table 2). The lack of arbuscule rates in Amaranthaceae root systems (A<5%) has been well documented (Becerra et al 2016), although, (Plenchette and Duponnois 2005) hypothesized about the existence in this family of a third AM morphological type with no arbuscules. Arum type morphology was present in all plant species, while Paris type was found in some roots of D. viscosa (Fig.…”

The potential of fi ve plants namely Atriplex halimus L., A. canescens (Pursh) Nutt., Suaeda fruticosa (Forssk. ex J.F. Gmel.), Marrubium vulgare L. and Dittrichia viscosa (L.) Greuter from two selected wetlands in northwest Algeria subjected to house and industrial effl uents were examined to assess their arbuscular mycorrhizal fungal (AMF) diversity and colonization, as well as to determine their tolerance and ability in accumulating metallic trace elements (MTEs). The purpose was to investigate whether, or not, these fungi are related to metallic uptake. Arbuscular mycorrhizal association was observed in all plant species, since the dual association between AMF and dark septate endophytes (DSE) was found in roots of 80% plants species. Hence, the decreasing trend of metal accumulation in most plant organs was Zn>Cu>Pb, and the most effi cient species were M. vulgare> S. fruticosa> A. canescens> D. viscosa> A. halimus. The bioaccumulator factors exceeded the critical value (1.0) and the transport factors indicated that all these species were phytoremediators. Pearson correlation showed that Cd bioaccumulation and translocation were inhibited by AMF infection; meanwhile Zn, Pb and Cd accumulation were affected by AMF spore density and species richness, DSE frequency, pH, AMF and plant host. Native halophytes showed a multi-metallic resistance capacity in polluted wetlands. M. vulgare was the most effi cient in metal accumulation and the best host for mycorrhizal fungi. AMF played a major role in metal accumulation and translocation.

“…En las últimas décadas se ha desarrollado diferentes estudios donde se emplean microorganismos benéficos con el fin de mejorar la productividad y sostenibilidad de los agroecosistemas. En el caso específico de las micorrizas, varias investigaciones han demostrado la eficiencia de los hongos micorrízicos como promotores en el desarrollo gracias al efecto positivo en la toma de nutrientes para plántulas de aliso, plátano papaya, guanábana, chirimoya, café, mango, limón, ají y aguacate entre otros (Becerra & Cabello, 2007;Cardona, Peña-Vengas, & Arcos, 2008;Silva & Siqueira, 1991;Usuga Osorio, Castañeda Sánchez, Franco Molano, Gómez Velásquez, & Lopera Agudelo, 2008;Viera et al, 2017).…”

Los suelos de la zona cálida tropical en su mayoría presentan problemas por deficiencia de fósforo, debido al bajo contenido natural del elemento y a la alta retención del mismo ocasionada por las condiciones químicas de los materiales edáficos.La región oriental de Colombia en la actualidad despunta con el mayor potencial para el crecimiento de la frontera agrícola, tanto en cultivos transitorios como perennes. El aguacate (Persea americana L), especie promisoria para esta región, presenta heterogeneidad en la producción, aspecto que le resta competitividad al cultivo. Una de las razones de esta problemática es el inadecuado manejo de la nutrición de las plantas en fase de vivero. Esta investigación tuvo como objetivo evaluar el efecto de la inoculación con micorrizas de los géneros Glomus y Acaulospora sobre la ganancia de biomasa en plantas de aguacate de las variedades Lorena, Santana y Común en fase de vivero, para lo cual se emplearon suelos procedentes de tres paisajes representativos de la Orinoquía colombiana, determinando la biomasa en hojas, tallo y raíz. Se encontró que la micorrización afecta positivamente la ganancia de materia seca. Glomus presentó diferencias significativas con respecto a Acaulospora, mientras que entre materiales de aguacate no se presentaron diferencias. Con base en los resultados obtenidos se recomienda el uso de hongos formadores de micorriza arbuscular como parte del manejo de la nutrición en plantas de vivero de P. americana L.
