“…Australian cedar seedlings inoculated with Claroideoglomus etunicatum and Acaulospora colombiana showed, respectively, an increase of 317 % and 236 % in the shoot dry matter production, if compared to uninoculated plants (Silva et al 2017). The higher photoassimilates production due to shoot intensification promotes better conditions for the maintenance of mycorrhizal symbiosis (Weirich et al 2018).…”

In the establishment of coffee crops, phosphate fertilization is one of the most important soil fertility managements. Aiming to minimize losses, among the options in use are fertilizers with a slow release of nutrients, combined with the inoculation of arbuscular mycorrhizal fungi (AMF). This study aimed to evaluate the initial growth of coffee plants inoculated with AMF and submitted to different types of phosphate fertilizers. The experiment was conducted in a greenhouse, using a complete randomized block design, in a 2 x 4 factorial scheme, with four replications. The first factor referred to the presence or absence of AMF (Rhizophagus clarus) and the second one to phosphate [monoammonium phosphate (MAP)], pelletized organomineral and grainy organomineral fertilizers, as well as a control (without fertilization). The plant height, leaf chlorophyll content, number of plagiotropic branches, leaf area, shoot and root dry matter mass, percentage of root colonization and leaf phosphorus were evaluated. The inoculation with AMF, associated with the pelletized organomineral fertilizer, provided a higher growth for the shoot and root system and higher phosphorus contents, in relation to the other treatments, and it can be an alternative to the implantation or renewal of coffee crops.

“…Hill & L.A.S. Johnson) Myrtaceae, Weirich et al (2018) obtained lower root dry mass when inoculated with the UFSC-PT116 isolate. Despite the reduction in root dry mass of plants inoculated with the UFSC-PT116 isolate with Cu doses, the formation of a mycorrhizal association results in an increase in the absorption area of the root of the plant because of the presence of fungal hyphae (Smith and Read, 2008), modifying the architecture of the roots that become shorter and more branched (Raven et al, 2007).…”

Copper (Cu) is one of the main heavy metals contaminating the soil. Plants have different behavior in terms of tolerance and toxicity to metals, being able to grow and produce even in soils contaminated with high concentrations. This study aimed to determine the influence of ectomycorrhizal fungi on the growth and tolerance of yerba mate plants grown in soil contaminated with Cu. The design was completely randomized in a factorial arrangement (4x6), with four possibilities of inoculum: without inoculum (control) and three ectomycorrhizal fungi (UFSC-PT116 — Pisolithus microcarpus, UFSC-PT132 — Pisolithus tinctorius and UFSC-SU118 — Suillus cothurnatus), with six Cu doses amended to the soil (0, 80, 160, 240, 320 and 400 mg kg-1 of Cu) in seven replicates. The height of the aerial part, the diameter of the lap, the dry mass of the aerial part and root system, the leaf area, the specific surface area of the roots, the contents of Cu in the aerial and radicular parts, the tolerance index, and mycorrhizal association were assessed. Inoculation of Ilex paraguariensis seedlings with ectomycorrhiza fungi UFSC-PT116, UFSC-PT132, and UFSC-SU118 mitigates the toxicity effect caused by the excess of Cu in the soil. The UFSC-PT116 isolate promoted the highest growth and tolerance of Ilex paraguariensis seedlings under the treatments. In general, the isolates promoted the reduction of Cu toxicity in Ilex paraguariensis plants, being an important alternative to remediate Cu-contaminated areas.

A fixação biológica de nitrogênio (FBN) realizada por bactérias diazotróficas é um processo natural e contribui para a viabilidade econômica e sustentabilidade do sistema de produção. Nesse sentido, o presente trabalho objetivou caracterizar bactérias promotoras do crescimento em eucalipto, assim como a interação delas com doses de nitrogênio no desenvolvimento inicial de mudas de eucalipto. As estirpes bacterianas utilizadas no experimento foram JM2R, JN5R, JN6R e LG2F. Realizou-se o experimento em vasos com capacidade de 20L, com delineamento em blocos casualizados (DBC), composto por 3 repetições e fatorial duplo 5x4, onde o primeiro fator era composto pelos isolados e um controle e, o segundo fator os níveis de nitrogênio (0, 25, 50 e 70 kg ha-1). Os parâmetros avaliados foram altura, número de brotações, massa seca de parte aérea e massa seca de raiz. A interação dos fatores foi significativa, e para altura e massa seca de parte aérea a dose de 70 kg ha-1 proporcionou as maiores médias.
