“…The viability and efficiency of the inocula can be maintained for several months at 20-25 °C, but the inocula should be kept in its packaging and must be partially dried [49]. It is important to stress that the inocula must be dried before storage [50,51].…”

Arbuscular mycorrhizal (AM) fungi are often applied as bio-inoculants due to their plant growth promoting benefits. The objectives of the present work were to maximize the shelf life of monoxenically produced carrier-based AM fungal bio-inocula of Rhizoglomus intraradices and Funneliformis mosseae. Shelf life of in vitro produced inoculum was studied by assessing the infectivity potential of in vitro produced inocula in an optimum carrier formulation (vermiculite: cow dung powder: wood powder: wood ash in the ratio of 20:8:2:1) during storage at three different temperatures viz., 4 °C, 25 °C and room temperature (RT). The re-germination potential of in vitro produced spores from carrier-based inocula to in vitro conditions was also examined. The in vitro produced inocula stored at 25 °C remained viable up to 6 mo in the organic carrier formulation. 100 % germination was recorded when the spores of both AM species were cultured back to in vitro conditions indicating high viability, and efficiency of the carrier formulation in maintaining vigour of in vitro produced propagules.

“…10 mM), the growth of the fungal hyphae is inhibited and the AMF colonization is reduced (Nagahashi et al, 1996). Among other factors that could affect AFM colonization are the use of monoculture, tillage (Berruti et al, 2014), modern agricultural practices (Toth et al, 1990;Hetrick et al, 1992), and, still controversial, genetically modified crops (e.g. maize; Liu, 2010).…”

Microbes and plants have evolved biochemical mechanisms to communicate with each other. The molecules responsible for such communication are secreted during beneficial or harmful interactions. Hundreds of these molecules secreted into the rhizosphere have been identified, and their functions are being studied in order to understand the mechanisms of interaction and communication among the different members of the rhizosphere community. The importance of root and microbe secretion to the underground habitat in improving crop productivity is increasingly recognized, with the discovery and characterization of new secreting compounds found in the rhizosphere. Different omic approaches, such as genomics, transcriptomics, proteomics, and metabolomics, have expanded our understanding of the first signals between microbes and plants. In this review, we highlight the more recent discoveries related to molecules secreted into the rhizosphere and how they affect plant productivity, either negatively or positively. In addition, we include a survey of novel approaches to studying the rhizosphere and emerging opportunities to direct future studies.

“…The highest infection, observed in non-mycorrhized nitrogen fertilized plants, suggested that the infection may be attributed to the presence of indigenous mycorrhizal fungi in the soil and that nitrogen supply exerts a positive effect on them [61]. The initial nutrient status of ecosystems may determine responses of AMF to fertilization, as the presence of high levels of fertilizer in the soil dramatically alters the interaction between plants and microbial communities [62]. As such, N additions could raise native AMF community in the N limited sites [63] more than the inoculation of a commercial fertilizer based on AMF.…”

Sorghum Biomass Production for Energy Purpose Using Treated Urban Wastewater and Different Fertilization in a Mediterranean Environment

et al. 2016

Abstract:With the aim at enhancing the sustainability of biomass production in the Mediterranean area, this paper analyzes, for the first time, the production of sorghum (Sorghum bicolor (L.) Moench) biomass for bioenergy production using urban treated wastewaters and bio-fertilization. For this purpose, the effects on biomass production of three different fertilizations (no-nitrogen control, biofertilizer, and mineral ammonium nitrate), four levels of constructed wetland (CW) wastewater restitutions (0%, 33%, 66% and 100%) of crop evapotranspiration (ETc) and three harvesting dates (at full plant maturity, at the initial senescence stage, and at the post-senescence stage) were evaluated in a two year trial. For bio-fertilization, a commercial product based on arbuscular mycorrhizal fungi was used. Mineral nitrogen (N) fertilization significantly increased dry biomass (+22.8% in the first year and +16.8% in the second year) compared to the control (95.9 and 188.2 g·plant −1 , respectively). The lowest and highest biomass production, in 2008 and 2009, was found at 0% (67.1 and 118.2 g·plant −1 ) and 100% (139.2 and 297.4 g·plant −1 ) ETc restitutions. In both years, the first harvest gave the highest biomass yield (124.3 g·plant −1 in the first year and 321.3 g·plant −1 in the second), followed by the second and the third one. The results showed that in Mediterranean areas, constructed wetlands treated wastewaters, when complying with the European restrictions for their use in agriculture, may represent an important tool to enhance and stabilize the biomass of energy crops by recycling scarce quality water and nutrients otherwise lost in the environment.
