El estudio se realizó en las instalaciones del Centro de Investigación y Enseñanza Forestal (CIEFOR) Puerto Almendra, ubicado en el distrito de San Juan Bautista, provincia de Maynas, región Loreto. El objetivo fue valorar económicamente el secuestro CO2 en plantaciones de Parkia sp. "pashaco" de diferentes edades en el CIEFOR Puerto Almendra, lquitos-Perú. El trabajo de investigación se ejecutó en una superficie de 3850 m2; donde se consideró 3 parcelas ubicadas en las diferentes instalaciones del CIEFOR Puerto Almendra, realizando el inventario forestal y georreferenciando cada árbol. Los resultados indican que la parcela de 27 años presenta mayor valor económico con US$ 1421,41/ha, significa que durante los 27 años a secuestrado 265,19 tCO2/ha, sin embargo en la parcela de 22 años y en la parcela de 6 años presentan menor valor económico de US$ €>43,05/ha y US$ 25;21...

Teak (Tectona grandis L.f.) is a leading tropical plantation species valued for high-quality timber and carbon (C) storage. This study assessed stand growth across ages and sites, quantified biomass and C by tree component and stand, and developed DBH-based allometric equations for biomass and C estimation. Six stand ages (5, 6, 9, 11, 14, and 17 years) were assessed in three municipalities of Nayarit, Mexico. Dendrometric inventories in permanent plots and destructive sampling of 35 trees provided calibration data for leaves, branches, stem, and roots. C concentration was determined with an elemental analyzer, and nonlinear regression models were adjusted and validated. Stand biomass and C increased with age, peaking at ages 11–14 (>130 Mg ha⁻¹; >60 Mg C ha⁻¹), with lower values at age 17. San Blas and Rosamorada accumulated significantly more than Tuxpan, reflecting site qualit...

The growing demand for Calycophyllum spruceanum is causing strong pressure on natural populations due to anthropogenic activities. For this reason, it is urgent to develop propagation technologies and production of plants for reforestation activities and establishment of forest plantations for their use and conservation. The objective of this study was to determine the effect of different substrates and containers on the emergence and growth of C. spruceanum. For this purpose, two experiments were conducted. In the first, four substrates were tested to evaluate seedling emergence, while in the second, the growth and quality of plants in different containers and substrates were determined. The maximum emergence values of 62.3%, emergency speed index (ESI) of 2.2, and mean emergence time of 29.9 were determined using a combination of carbonized rice husk (CRH), chicken manure, and decompos...
