Revista árvore , 2003,
Abstract: Avaliou-se a variabilidade da tratabilidade da espécie madeireira Brosimum rubescens Taub. Moraceae (pau-rainha), abordando três diferentes alturas do tronco (base, meio e ápice) e duas partes (cerne e alburno). O processo utilizado foi o de impregna o sob press o, através do método de célula-cheia ou Bethell, e o preservante foi o CCA, tipo A, a 2% de concentra o. A análise da variabilidade deu-se em fun o da reten o. Ao comparar os dados de reten o (kg/m3) das diferentes alturas e partes do tronco, constatou-se que o grau de tratabilidade do alburno é moderadamente difícil, enquanto o cerne é refratário. Os resultados de reten o das toras estudadas nas diferentes alturas da árvore n o apresentaram diferen a significativa, entretanto existe diferen a significativa de reten o entre as partes (cerne e alburno). A análise de microdistribui o do preservante através do estudo anat mico funciona como ferramenta auxiliar na interpreta o desses resultados.

Psyche , 2012, DOI: 10.1155/2012/480520
Abstract: An experiment was conducted in a primary forest area of the Tropical Forest Experimental Station, 45 km from Manaus-Boa Vista Highway, in order to compare the insect fauna of the subfamily Scolytinae, in flight activity and on the ground. Five impact traps of the type Escolitideo/Curitiba, with ethanol baits, were installed at the height of 3 m above the ground, and five pitfall traps were buried in the same area of the above ground traps. The data collections were evaluated through abundance, richness, and Simpson diversity index, and, to compare these data with the pitfalls and the months collection, the ANOVA was used. The Pearson correlation test was also carried out to evaluate the meteorological factors (temperature and rainfall). From the total of 2,910 Scolytinae, 2,341 were captured in pitfall traps representing 80.45% and 569 with Escolitideo/Curitiba traps representing 19.55%. The most abundant species in the collections were Xyleborus volvulus Fabricius and Xyleborus affinis Eichhoff, and this was classified as constant in both habitats. The result of the analysis indicates that the Simpson’s index was high and that the abundance of insects was affected by the types of trap and by the month of collection. The analysis of correlation with meteorological factors showed that only Xyleborus spinulosus species presented significant correlation with temperature.

Ambiência , 2013,
Abstract: O Lentinus strigosus (Schwein.) Fr. é um cogumelo comestível ainda pouco cultivado, de ocorrência na Amaz nia brasileira, que pode ser explorado. Para viabilizar economicamente o seu cultivo, a exemplo de outros cogumelos comestíveis, é recomendado a utiliza o de resíduos regionais de baixo ou nenhum custo. Assim, verificou-se o crescimento micelial de L. strigosus em meios de cultura preparados à base de extrato de resíduos madeireiros regionais (serragem) de breu (Protium puncticulatum), tauari (Cariniana micrantha) e piquiarana (Caryocar glabum) suplementadas com 20% de farelo de trigo (Triticum aestivum), farelo de milho (Zea sp.) ou farelo de arroz (Oryza sp.). A serragem de eucalipto (Eucalyptus sp.) foi utilizada para compara o com os demais resíduos madeireiros, por ser um resíduo comumente utilizado no cultivo de fungos comestíveis. O delineamento experimental utilizado foi inteiramente casualizado, em esquema fatorial 4 x 3 (serragens x farelos), totalizando 12 tratamentos com 5 repeti es, sendo cada repeti o correspondente a uma placa de Petri, totalizando 60 placas, incubadas a 35 oC. Avaliou-se, diariamente, o diametro da col nia até que, em um dos tratamentos, o fungo atingiu as proximidades da placa de Petri. Após esse período, observou-se que o meio à base de extrato de serragem de breu proporcionou melhor desempenho de crescimento micelial do L. strigosus e apresenta, desta forma, potencial para ser utilizado como um resíduo alternativo em uma futura produ o de L. strigosus no estado do Amazonas.

Ambiência , 2011,
Abstract: O objetivo do trabalho foi avaliar o crescimento micelial in vitro de cinco linhagens de Agaricus blazei (ABL-05/53, ABL-04/49, ABL-03/44, ABL-99/30 e ABL-02/51), quando submetidas às temperaturas de 20 e 25oC. Em camara de fluxo laminar, discos das linhagens foram inoculadas no centro de placas de Petri contendo o meio CA (composto-ágar) e incubadas em estufa BOD. Após 48 horas, iniciaram-se as medidas do crescimento micelial, com auxílio de uma régua graduada em milímetros, através de quatro medi es equidistantes entre si, até o momento em que, em um dos tratamentos, a col nia fúngica atingisse a proximidade das bordas da placa de Petri. O delineamento experimental foi inteiramente casualizado, em esquema fatorial 5 x 2. Cada tratamento constou de sete repeti es, correspondente a uma placa de Petri, totalizando setenta unidades experimentais. Verificou-se que o crescimento de A. blazei é influenciado pela temperatura de incuba o, sendo que a temperatura de 25°C foi mais favorável para o crescimento micelial de todas as linhagens de A. blazei avaliadas, com destaque para as linhagens ABL-04/49 e ABL-03/44 que obtiveram as maiores médias de crescimento micelial nesta condi o de temperatura ao final do ciclo de cultivo.AbstractThe objective of the work was to evaluate the in vitro mycelial growth of five A. blazei strains (ABL-05/53, ABL-04/49, ABL-03/44, ABL-99/30 and ABL-02/51) when submitted to the temperatures of 20 and 25 oC. In a laminar flow chamber, discs of the strains were inoculated in the middle of Petri’s plates containing CA (compost-agar) medium and incubated in BOD. After 48 hours, measurements of the mycelial growth began, with the help of a ruler with scale in millimeters, by means of four equidistant measurements, until the moment when the fungal colony reached near the edges of the Petri’s plate in one of the treatments. The experimental design was totally randomized, in 5 x 2 factorial design. Each treatment consisted of seven repetitions, corresponding to one Petri’s plate, totalizing seventy experimental units. We verified that A. blazei growth is influenced by incubation temperature, being that the temperature of 25 oC was more favorable for the mycelial growth of all A. blazei strains tested, with attention for ABL-04/49 and ABL-03/44 strains, which obtained the highest averages for mycelial growth under this temperature condition at the end of the cultivation cycle.
