Abstract:

La intercepción de precipitación en plantaciones de V. ferruginea Mart. y V. guatemalensis Donn. Sm. fue estudiada en la estación biológica La Selva, Heredia, Costa Rica. Se realizaron mediciones diarias de precipitación bruta, precipitación de copas y escorrentía fustal de agosto a noviembre del 2004. Se determinó estadísticamente si el número de pluviómetros utilizados fue el correcto para una precisión aceptable. El porcentaje de precipitación de copas para V. ferruginea fue de 87,65% de la precipitación bruta, en V. guatemalensis fue del 92,12%. Los porcentajes de escorrentía de fuste fueron 2,98% y 3,39% de la precipitación bruta respectivamente. Las pérdidas totales por intercepción en V. ferruginea fueron de 9,37% de la precipitación bruta, en V. guatemalensis fueron de 4,49%.

Abstract:

Se evaluaron cuatro eventos fenológicos (floración, fructificación, caída y brote de hojas) en Schizolobium parahyba (Vell.) Blake y Vochysia guatemalensis Donn.Smith., dos especies arbóreas de la selva húmeda en el norte de Oaxaca, México, con relación a la precipitación y temperatura del aire durante un año (septiembre 2006-septiembre 2007). Además, la humedad del suelo y el potencial hídrico de los árboles se midió al final de la sequía (abril-mayo 2007) e inicio de las lluvias (junio-julio 2007). Los resultados mostraron correlaciones significativas (P < 0.01) entre la precipitación y la fructificación en ambas especies (r = 0.89) y el brote de hojas en S. parahyba (r = 0.88). Los valores registrados de humedad del suelo (%) y potencial hídrico (bar) fueron: S. parahyba (8 a 25%, -11 a -1 bar) y V. guatemalensis (13 a 30%, -5.8 a -1.5 bar). El estrés hídrico fue mayor en algunos árboles de S. parahyba que en todos los de V. guatemalensis. Schizolobium parahyba es una especie cuya fenología está asociada a la estacionalidad del clima y V. guatemalensis no tiene una fenología determinada por la estacionalidad climática, sino por factores endógenos o geográficos.

Abstract:

Alnus acuminata, Vochysia ferruginea, and Vochysia guatemalensis are three low-density wood species used for reforestation in Costa Rica. The goal of this work was to study a thermo-hydro-mechanical densification process and test the characteristics of densified wood of these species. Twelve densifying treatments based on temperature, compression time, and use/no use of steam were tested. The variables of the densification process and the properties of the densified wood were determined. The results showed that the densification percentage was over 80% for wood of A. acuminata and over 70% for wood of V. ferruginea and V. guatemalensis. In the three species, the densification process was influenced by initial density. The influence of temperature during the densification process affected the heating rate and color change. An increase in the modulus of elasticity and modulus of rupture in static bending and in the hardness of the densified wood relative to the normal wood was observed, as well as a clear positive correlation of the properties with final density and maximum load, the latter being highly correlated with initial density. This showed that initial density was significant in the densification process and affects wood properties.

Abstract:

The dependence of tree seedling survival and growth on light availability was evaluated over 15 mo in three second-growth, wet forest stands (15–18 y old) in north-eastern Costa Rica. Seedlings of four canopy tree species (Dipteryx panamensis, Hyeronima alchorneoides, Virola koschnyi and Vochysia guatemalensis) were planted into four canopy treatments in three replicated stands and in a pasture site, spanning a nearly complete gradient of light availability. Survival and growth of all species increased in response to increasing light availability, but species differed in survival in shaded microsites (6–20% light transmittance) and in growth increments per light increase. Hyeronima showed the highest mortality at low light levels and the highest relative height growth increase per light increase. In contrast, Virola showed high survival at low and moderate light, but showed the lowest leaf area and above-ground biomass per light increase among all species. Dipteryx and Vochysia maintained relatively high rates of survival and growth across the entire light gradient. Hyeronima and Virola showed trade-offs between growth and survival responses to light, unlike Dipteryx and Vochysia. Differences among species in seedling survival at low light may be determined by a variety of physiological and morphological traits that may or may not be mechanistically linked to growth responses.

Abstract:

Natural-grown and young (5.5 year old) plantation-grown trees were sampled for two Central American hardwood species: Hyeronima alchorneoides and Vochysia guatemalensis in the Atlantic lowlands of Costa Rica. Increment cores extracted at a height of 1.3 m from trees were divided into 1cm segments from pith to bark. Basic specific gravity was calculated for each segment. Using the same cores, fibre length was measured from macerations for five natural and plantation-grown trees of each species. Number of vessels/mm2 and vessel tangential diameter were measured from segment cross sections for five natural-grown trees of each species.

Abstract:

Se estimó la biomasa aérea de Vochysia guatemalensis Donn. Smith., una especie de importancia ecológica y económica en el sur-sureste de México. Se derribaron siete árboles de cuatro categorías diamétricas (10, 15, 20 y 25 cm), para luego separarlos por componente estructural. De cada componente se obtuvieron muestras que se pesaron en fresco y se secaron en estufa. Con estos datos se estableció el peso seco para estimar la biomasa por componente y árbol total en cada categoría, ajustando ecuaciones alométricas mediante técnicas de regresión no lineal. Los valores de biomasa aérea por árbol uctuaron de 8.264 a 105.099 kg en fustes, de 0.329 a 21.442 kg en ramas y de 0.393 a 9.609 kg en follaje. A nivel de árbol 79.68 % de la biomasa se encontró en fustes, 13.58 % en ramas y 6.72 % en follaje.
