Última Efecto de aclareos en el crecimiento de una plantación de Pinus patula Schl. et Cham. en Ixtlán, Oaxaca. Colegio de Postgraduados Rodríguez Ortíz, Gerardo. La eficiencia de crecimiento (EC) es la relación entre el follaje o el área de albura del fuste y el incremento maderable del árbol. Con este índice es posible analizar la respuesta del crecimiento y fisiología del fuste a factores de calidad de sitio, la edad, el aclareo y la densidad del rodal. El objetivo de este trabajo fue estimar y analizar los componentes de biomasa aérea y la eficiencia de crecimiento en árboles de Pinus patula Schl. et Cham. sujetos a aclareos en una plantación en Ixtlán, Oaxaca. En 2009 se realizaron muestreos destructivos en 30 árboles localizados en parcelas aclareadas y un testigo, para obtener muestras del componente aéreo. La biomasa de acículas por rama se estimó utilizando variables más susceptibles a las variaciones del...

This paper presents results obtained for fitting equations to estimate volume and weight of aerial compartments of Grevillea robusta trees. Twelve trees representing four provenances were collected from an eight-year-old provenance trial located in the municipality of Anhembi, State of São Paulo. The trunks of the trees were segmented until the minimum diameter of 5 cm. The heartwood was measured till the height it was possible to be distinguished in the tree. Allometric models were the most suitable for this paper proposes. The inclusion of the combined variable (total height multiplied by the diameter at breast height) contributed to a better adjustment of most equations. The standard errors of the estimates were relatively high for heartwood and bark...

Ano: 2004 URL: http://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/1292 African Mahogany transpiration with Granier method and water table lysimeter AGRIAMBI Sérvulo,Ana C. O.; Vellame,Lucas M.; Casaroli,Derblai; Alves Júnior,José; Souza,Pedro H. de. ABSTRACT The thermal dissipation probe (Granier method) is useful in the water deficit monitoring and irrigation management of African Mahogany, but its model needs proper adjustment. This paper aimed to adjust and validate the Granier sap flux model to estimate African Mahogany transpiration, measure transpiration using lysimeter and relate it to atmospheric water demand. Weather conditions, transpiration and sap flux were monitored in three units of 2.5-year-old African Mahogany trees in constant water table lysimeter, in Goiânia, GO. Sapwood area (SA), leaf area (LA), transpiration measured by lysimeter (TLYS) and estimated by sap flux (TSF) were evaluated. The SA comprised 55.24% of the trunk’s transversal section. The LA varied from 11.95 to 10.66 m2.... Tipo: Info:eu-repo/semantics/article Palavras-chave: Khaya ivorensis; Sap flux; Transpiration; Lysimeter; Sapwood.
