| Aiming to evaluate the development of seedlings of Schinus terebinthifolius under different irrigation depth, an experiment was installed in a greenhouse. The experimental design used was randomized block consisting of 4 treatments with 3 blocks. The irrigation depths evaluated were 8, 10, 12 and 14 mm daily, respectively T1, T2, T3 and T4. Seedling production was performed in tubes with 280 cm ³ filled with pine bark basis substrate and fertilizer. The development of the seedlings, were evaluated by the following characteristics: height of aerial part (APA), diameter at breast height (D),dried mass weight of roots (PMSR), dried mass weight of aerial part (PMSPA), total dried mass (MST) and relation (h/d). The treatment T3 presented the best results in... |

| O presente estudo objetivou avaliar o uso da constante elástica dinâmica obtida no ensaio não destrutivo, como parâmetro para estimativa das propriedades mecânicas de rigidez e resistência da madeira de Eucalyptus grandis. Para isto, utilizou-se um emissor de ondas ultrassônicas, o qual teve sua sensibilidade avaliada através da comparação com os valores obtidos no ensaio destrutivo de flexão estática. Os resultados evidenciam que a constante elástica dinâmica pode ser utilizada para inferência não destrutiva da rigidez e resistência da madeira de Eucalyptus grandis, entretanto com ressalvas, pois os ajustes observados foram relativamente baixos, com R²aj. de 0,25 e 0,39, respectivamente. doi: 10.4336/2012.pfb.32.69.109 |

| This study aimed to verify the basic density influence in dynamic bending trails of Hovenia dulcis Thunb wood. In order to do so, 34 samples of heart wood were used, with the following dimensions: 30 x 2 x2 cm (longitudinal, radial and tangential) respectively, according to the Brazilian standard, NBR 7190 (1997). The samples were evaluated for their basic density for the rate between the weight in 12% of moisture and its respective volume and posteriorly, it was separated in two groups: the first with specific weight between 0,55 and 0,64 g/cm³ and the second one between 0,65 and 0,75, aiming the comparison between the treatments. The wood resistance for the dynamic bending was estimated, using the Charpy’s impact test, in the radial direction.... |
