“…However, the values found in this study for the three experiments were higher than those presented by Góes et al (2015) for I. laurina seedlings. Those authors obtained DQI values ranging from 0.36 to 0.43 after inoculation with N-fixing bacteria, whereas they obtained a value of 0.97 for the treatment that received N fertilizer.…”

Inga edulis Mart. is a leguminous tree adapted to acidic and low-fertility soils that establishes symbioses with nitrogen (N)-fixing bacteria. The identification of effective bacteria in biological N fixation may bolster the use of I. edulis in degraded or modified areas and agroforestry systems. Therefore, the aims of this study were evaluation of the symbiotic effectiveness of eight strains of the Bradyrhizobium genus native to Roraima in Inga edulis plants, and in vitro evaluation of the ability of the eight strains of Bradyrhizobium to develop plant growth-promoting characteristics. Determination of symbiotic effectiveness was carried out via three experiments: the first in a greenhouse in pots with a sterile substrate; the second in a greenhouse in pots containing non-sterile soil; and the third in a nursery in bags with a non-sterile substrate. Twelve treatments were evaluated: inoculation with eight strains of Bradyrhizobium ingae (ERR 490, ERR 492, ERR 493, ERR 494 T , ERR 496, ERR 497, ERR 498, and ERR 569); inoculation with two strains indicated for Inga marginata, BR 6609 and BR 6610 (positive controls); no inoculation but with mineral N; and neither inoculation nor mineral N. All of the experiments were conducted in a completely randomized design with four replicates. The first experiment was conducted for 60 days, and the other experiments were conducted for 100 days. For all of the experiments, the number of nodules, nodule dry matter, root dry matter, shoot dry matter, number of leaflets, plant height, stem diameter, total N in the shoots, root/shoot dry matter ratio, Dickson's quality index, relative effectiveness, and the Pearson correlation between the variables under study were evaluated. The strains were also evaluated by their ability to solubilize calcium and aluminum phosphates and to produce indolic compounds. The results showed that B. ingae strains were effective in biological N fixation, especially the ERR 493, ERR 498, and ERR 569 strains. These strains increased the production of shoot dry matter and total N and exhibited relative effectiveness higher than 100 % in all of the experiments. The B. ingae strains were also able to solubilize calcium and aluminum phosphates, despite their synthesis of indolic compounds. Thus, the strains of B. ingae can be used for inoculation in the production of I. edulis seedlings.

“…A TCR e a TAL são variáveis utilizadas em análise do crescimento de plantas, sendo que a TCR relaciona o incremento em biomassa a partir da biomassa préexistente e a TAL relaciona o incremento em biomassa a partir da área foliar (Hunt, 1990). Os valores de TCR obtidos nesse estudo foram relativamente semelhantes entre os dois experimentos e próximos aos valores obtidos por Góes et al (2015) para mudas de I. laurina, utilizando uma mistura de 90% HSF e 10% PFC, com adubação suplementar. Os valores médios da TAL obtidos no experimento I (com adubação suplementar), por outro lado, foram inferiores aos valores obtidos no experimento II (sem adubação suplementar) (Tabela 3) e aos valores relatados por Góes et al (2015).…”

No caso da TAL, as diferenças verificadas entre os experimentos podem estar relacionadas com o aumento da capacidade fotossintética das folhas, em função do tempo de permanência no viveiro, visto que a TAL apresenta relação direta com a taxa fotossintética líquida (Montgomery, 2004;Feijó et al, 2009).…”

Resumo -O objetivo deste estudo foi avaliar o efeito de misturas de um substrato comercial e pó de fibra de coco (PFC) no crescimento e na qualidade de mudas de Inga laurina (Sw.) Willd. (Fabaceae). Tubetes de polietileno foram preenchidos com quatro misturas do substrato comercial HS Florestal® (HSF) e PFC nas proporções: T1 = 100% HSF; T2 = 80% HSF + 20% PFC; T3 = 60% HSF + 40% PFC e T4 = 40% HSF + 60% PFC. Os experimentos foram realizados de forma independente, em presença (experimento I) e ausência (experimento II) de adubação suplementar. Foram realizadas avaliações de crescimento e qualidade das mudas ao final dos experimentos, aos 81 dias (experimento I) e 110 dias (experimento II) após a repicagem. Concluiu-se que o uso da adubação suplementar não apresentou diferenças em crescimento e qualidade das mudas de I. laurina até o percentual de 60% de PFC misturado ao substrato comercial. Sem a adição de adubação suplementar, a mistura com 80% HSF + 20% PFC é indicada para a produção de mudas de I. laurina. Além disso, a ausência de adubação suplementar nitrogenada e a adição de PFC ao substrato estimularam a nodulação. Growth and quality of Inga laurina seedlings as a function of the substrate and additional fertilizationAbstract -The aim of this study was to evaluate the effect of mixtures of a commercial substrate and coconut coir dust (CCD) to grow Inga laurina (Sw.) Willd. (Fabaceae) seedlings. Polyethylene tubes were filled with four mixtures of a commercial substrate HS Florestal® (HSF) and CCD in the following proportions: T1 = 100% HSF, T2 = 80% HSF + 20% CCD, T3 = 60% HSF + 40% CCD and T4 = 40% HSF + 60% CCD. The experiments were conducted independently, with supplement fertilization (experiment I) and without (experiment II). Seedlings growth and quality were evaluated at the end of the experiments, 81 days (experiment I) and 110 days (experiment II) after transplanting. It was concluded that supplement fertilization presented no differences in the growth and quality of I. laurina seedlings until up to 60% of PFC mixed with commercial substrate. Without supplement fertilization the mix of 80% HSF + 20% PFC is indicate for production of I. laurina seedlings. Moreover, the lack of supplement nitrogen fertilization and addition of PFC to the commercial substrate stimulated nodulation.

“…58894 The plants were placed in the soil and substrate still small (seedlings) and the age of the plant may have influenced the growth response to inoculation, since mycorrhizal fungi, as well as promoting growth and/or nitrogen-fixing bacteria in the production phase of seedlings in nursery or even in the field make seedlings more responsive in development, quality and resistance to adverse conditions. The use of previously-inoculated larger seedlings could enable better development of the plants, since when seedlings are still in adaptation they can respond negatively to the soil or cultivation substrate, but when they are larger the probability of adaptation is greater (GÓES et al, 2015;DALANHOL et al, 2016).…”

Mining results in major landscape changes. Restoring areas after exploitation of natural resources can be accomplished through adopting techniques used to optimize the restoration process. Among such techniques, planting seedlings of species adapted to adverse edaphoclimatic conditions and which have interspecific associations with microorganisms stand out. One of these indigenous species which occur in the Southern Espinhaço Mountain Range with potential for use in restoring degraded areas is Kielmeyera rubriflora (Spreng) Mart. Thus, the objective of this study was to evaluate the influence of inoculating arbuscular mycorrhizal fungi on the survival and growth of Kielmeyera rubriflora Cambess. on two substrates from iron mining. The experiment was carried out in a nursery of the UFVJM Plant Species Propagation Center (CIPEF) in a randomized block design and treatments arranged in a 2 x 2 factorial design, using two iron mining substrates and inoculated and uninoculated plants with five repetitions. The seedlings received 25 g of the soil-inoculum mixture of Paraglomus occultum (C. Walker) JB Morton & D. Redecker and Claroideoglomus etunicatum (WN Becker & Gerd) C. Walker & A. Schüßler at the transplantation time to 17 dm3 pots. Stem diameter and leaf number were influenced only by the main effects of substrate and inoculation, while plant height was influenced by the interaction between substrate and inoculation. Inoculation with mycorrhizal fungi in Kielmeyera rubriflora ensures survival, species growth and root development on both iron mining substrates and is a suggested strategy for planting in areas degraded by iron mining.
