El objetivo de este trabajo fue determinar el efecto de diferentes sustratos y recipientes en la emergencia y crecimiento inicial de Calycophyllum spruceanum. El estudio fue conducido en dos experimentos, en el primero, se probaron cuatro sustratos (arena fina de rio (testigo), suelo aluvial, aserrín descompuesto y cascarilla de arroz carbonizada + gallinaza + aserrín descompuesto (1:1:1)), para evaluar la emergencia de plántulas, mediante las variables: porcentaje de emergencia (%E), índice de velocidad de emergencia (IVE), y tiempo medio de emergencia (TME). El segundo experimento fue del tipo factorial con dos factores: recipientes (bolsa y tubete) y sustratos, para evaluar el crecimiento y calidad de plantas, mediante las variables: altura (H), diámetro basal (DB), número de hojas (NH), índice crítico de clorofila (ICC), biomasa húmeda total (BHT), biomasa seca total (BST), ...

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...
