“…The response of nodulation of scandent species to different substrates was similar to the response of several native tree species reported by Moreira (1995;1997), i.e., nodulation was greater in SAND, HG and CONV than in ULT and ULTfert substrates.…”

“…Different seed physiological maturation points (Moreira and Moreira 1996), or genetic and phenotypic variability between matrices individuals (provenances) may provide differences in the species' growth. For instance, Entada polystachya, which reached about 150 cm tall in previous work, from seeds collected in fertile soil of floodplain (Moreira 1995), did not exceed 30 cm in this work, with seeds from matrix found in dry land ("terra firme") with low fertility.…”

“…However, the best substrates are those using soils of the focused region because of the native rhizobia that they contain, which can be trapped and studied. (Moreira et al 1993;Moreira 1995;1997). The objective of this study was to evaluate the growth of eight species of scandent legumes in five nursery substrates; to compare nodulation of species nodulating with rhizobia strains introduced or native to these substrates; and to characterize phenotypic and genetically these rhizobia.…”

A great number of species and individuals of scandent legumes establishing symbiosis with nitrogen fixing bacteria occurs in the Amazon Forest. These symbiosis probably play an important role in contributing to nitrogen incorporation in this ecossystem. The objectives of this study were to evaluate the growth of eight species of scandent legumes in five nursery substrates; to compare nodulation with rhizobia strains introduced or native to these substrates; and to characterize phenotypically and genetically these rhizobia. The experiment was carried out in a completely randomized design with five replications. Five to seven months after seedling emergency, according to the legume species, growth and nodulation parameters were determined. Rhizobia identification of strains was carried out by 16S rRNA gene partial sequencing. The survival of seedlings after the transplanting varied from 93 to 98%, in Ultisol (Argissolo in Brazilian classification), collected in primary forest, and fertilized with all nutrients, except nitrogen (ULTfert); and in a clay and sand mixture, in a ratio 3:2 (CONV), respectively. Species with height superior to 30 cm, in general, grew better in substrates with higher fertility: ULTfert and Humic Gley soil (HG). Seven out of the eight species were able to nodulate. The percentage of nodulation per substrate was: SAND, washed sand with mixed inoculum of 100 rhizobia strains plus fertilization (100), HG (80), CONV (100), ULT, A-horizon of red-yellow Ultisol collected in the Ducke Forest Reserve (Manaus) (44), and ULTfert (55%). Bradyrhizobium spp. were isolated from nodules of all species and substrates. Burkolderia fungorum was isolated from Dalbergia inundata. For Dalbergia riedelli and Dalbergia inundata, this is the first report on the identification of symbiotic strains. Scandent legumes present high survival of seedlings in nursery, and develop better in substrates with higher fertility, and generally present symbiosis with Bradyrhizobium.

“…De acordo com Dumroese et al (2009), plantas não inoculadas e não fertilizadas podem apresentar nódulos. Isso pode ocorrer em ambientes onde as condições de assepsia dos experimentos não são totalmente controladas, como no caso de viveiros florestais, e a contaminação com bactérias nativas pode ocorrer pela deposição de partículas levadas pelo vento, pela ação humana, de outros animais ou por eventos de precipitação pluvial e irrigação (Moreira, 1997;Dumroese et al, 2009). Além disso, é bem conhecido o fato de que a fertilização nitrogenada inibe a formação de nódulos (Patreze & Cordeiro, 2005).…”

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.

“…Com relação ao crescimento inicial, as plântulas de várzea apresentaram maior crescimento, devido ao fato de possuírem mais reserva nutritiva em suas sementes (BUCKERIDGE et al, 2004;FERREIRA et al, 2009;BEWLEY et al, 2013), o que fica evidente no peso fresco e seco das sementes. Corroborando com essa afirmação temos o estudo de Moreira (1997), que verificou que espécies com maiores taxas de crescimento como S. polyphylla e Vatairea guianensis tinham as maiores sementes.…”

O estudo investigou se houve diferença na densidade de indivíduos, nos atributos funcionais foliares, na germinação e no crescimento das plântulas de pitaica (Swartzia polyphylla DC.) (Fabaceae) em duas florestas inundadas (igapó e várzea) da Estação Científica Ferreira Penna, em Caxiuanã, no estado do Pará. Houve diferenças significativas na densidade de plântulas e de plantas estabelecidas de pitaica (S. polyphylla) entre os dois tipos de floresta. Nos traços funcionais, houve diferença significativa na área foliar (LA) e no conteúdo de matéria seca foliar (LDMC), assim como no peso fresco e seco, comprimento e espessuras das sementes. Houve também diferença signifi cativa na taxa de germinação das sementes entre os ambientes. As curvas de crescimento das sementes foram semelhantes entre as fl orestas. Os resultados inferem que estratégias para o estabelecimento de sementes podem estar ligadas ao investimento em atributos funcionais diferentes nos ambientes (área foliar, área foliar específica e conteúdo de matéria seca foliar), já que a folha, por possuir todo o aparato fotossintético da planta, é o órgão que mais responde de forma plástica à variabilidade de condições ambientais.
