“…The results found in this study at 90 days with the use of R. clarus, R. clarus + C. etunicatum and R. clarus + G. margarita corroborate those obtained by Boff et al (2014), who also found that mixed inoculation with R. clarus + G. margarita was able to promote higher growth in Paricá seedlings compared to the control. Lucena et al (2013) also found that the height of Paricá plants inoculated with native arbuscular mycorrhizal fungi spores grown in a greenhouse was significantly higher when compared to the control group and chemically fertilized plants.…”

Arbuscular mycorrhizal fungi (AMF) occur in large numbers of plant species, especially in tree plants, and are present in almost all tropical soils. Their inoculation enables faster seedling growth and a higher survival rate in the nursery, thereby anticipating the transplant to the field. Despite these advantages, there is little information available on the efficiency obtained from the combination of different mycorrhizal species. In view of this, this work had the objective to evaluate the development of Paricá (Schizolobium amazonicum) seedlings from the association with different combinations of AMF species: Rhizoglomus clarus, Claroideoglomus etunicatum and Gigaspora margarita, isolated and combined under greenhouse conditions. The design was completely randomized, with seven treatments and fifteen replications, totaling one hundred and five experimental units. Three evaluations were carried out during the experiment at 30, 60, 90 days after sowing. The evaluated variables were plant height (H), stem diameter (SD), number of leaves (NL), fresh shoot weight (FSW), dry shoot weight (DSW) fresh root weight (FRW), dry root weight (DRW), height/diameter ratio (H/D) and Dickson Quality Index (DQI). It was found that there was a significant response of the treatments studied at a 5% probability level for most of the evaluated parameters. The results obtained in the present work allowed to conclude that the use of a mixed inoculation of Rhizoglomus clarus + Gigaspora margarita promoted better development and growth in Paricá plants under greenhouse conditions.

“…A deficiência nutricional limita a produção de mudas, principalmente nas regiões tropicais e subtropicais, pois nessas regiões predominam solos velhos e imtemperizados (NOVAIS et al, 1999), e as plantas não absorvem 10 % do fósforo total aplicado via adubação (MALAVOLTA et al, 1989).…”

“…Por meio dessa associação, a planta fornece ao fungo os carboidratos necessários ao seu crescimento, enquanto que este último, por meio de suas estruturas externas (hifas), auxilia a planta na absorção dos nutrientes, principalmente do fósforo (SILVA et al, 2009). Lucena (2013) observou que plantas de paricá (Schizolobium amazonicum), apresentaram maior crescimento quando inoculas com espécies de FMAs. Aguiar et al (2004) verificaram resposta positiva da inoculação dos FMAs na algaroba (Prosopis juliflora DC), principalmente na altura, diâmetro do colo e no número de folhas.…”

O experimento foi realizado na Estação Experimental de Engenharia Florestal do Campus Universitário de Gurupi, Universidade Federal do Tocantins (UFT), com objetivo de determinar a melhor dose de fósforo na presença de fungos arbusculares em mudas de guanandi (Calophyllum brasiliense Camb.) O delineamento experimental utilizado foi inteiramente casualizado com três repetições em esquema fatorial 6 x 2. Os tratamentos foram seis doses de fósforo (0; 400; 800; 1200; 1600 e 2000 g de P2O5 por m³) no substrato na presença e ausência de Fungos Micorrízos Arbusculares (FMAs). As características avaliadas foram altura das plantas, diâmetro do caule, massa seca da parte aérea (MSPA), massa seca da raiz (MSR), massa seca total (MST) e colonização micorrízica. Os diferentes níveis de adubação influenciaram a colonização micorrízica arbuscular. Nas doses 400 e 1600 g de fósforo por m3 de substrato observou-se maior porcentagem de colonização. A altura e o diâmetro das plantas foram significativamente afetados pela presença de P2O5. A massa seca da parte aérea e massa seca total não é afetada por doses de P2O5. O melhor desempenho das mudas de C. brasiliense ocorreu aos 90 dias com dose de 1.421 g de P2O5 por m3 de substrato.Palavras-chave: Calophyllum brasiliense Camb., adubação, micorrização. MYCORRHIZAL FUNGI AND PHOSPHORUS DOSES IN THE DEVELOPMENT OF GUANANDI SEEDLINGS ABSTRACT:The experiment was carried out at the Forest Engineering Experimental Station of the Federal University of Tocantins (UFT), University Campus of Gurupi, with the objective of determining the best dose of phosphorus in the presence of arbuscular fungi in guanandi (Calophyllum brasiliense Camb. The experimental design was completely randomized with three replicates in a 6 x 2 factorial scheme. The treatments were six doses of phosphorus (0, 400, 800, 1200, 1600 and 2000 g of P2O5 per m³) on the substrate in the presence and absence of Arbuscular mycorrhizal fungi (FMAs). The evaluated characteristics were plant height, stem diameter, shoot dry mass (MSPA), root dry mass (MSR), total dry mass (MST) and mycorrhizal colonization. The different levels of fertilization influenced arbuscular mycorrhizal colonization. At 400 and 1600 g of phosphorus per m3 of substrate, a higher percentage of colonization was observed. The height and diameter of the plants were significantly affected by the presence of P2O5. Dry shoot mass and total dry mass are not affected by P2O5 doses. The best performance of C. brasiliense seedlings occurred at 90 days with a dose of 1421 g of P2O5 per m3 of substrate.Keywords: Calophyllum brasiliense Camb., fertilization, mycorrhization. DOI:

“…O amido é o mais importante polissacarídeo de reserva do reino vegetal e amilases constituem um grupo de enzimas que possuem ação sobre esse carboidrato (Gupta et al, 2003). Assim, micro-organismos produtores dessas enzimas afetam diretamente a disponibilidade de nutrientes para as plantas e para outros micro-organismos, bem como as propriedades químicas e físicas dos solos (Jeffrey et al, 2007 três amostras equidistantes entre si, que foram unidas para formar uma amostra composta (Lucena et al, 2013 …”
