Piper aduncum es un arbusto o arbolillo distribuido a lo largo de América en el que se han identificado numerosos compuestos biológicamente activos. Diferentes combinaciones de reguladores de crecimiento fueron ensayadas para la propagación clonal, la inducción y mantenimiento de callos y el establecimiento de suspensiones celulares. Los resultados mostraron una significativa mayor elongación del brote en el tratamiento con medio de cultivo B5 suplementado con AIA 0,02 mg/L y AG3 0,02 mg/L en comparación con otros tratamientos, la inducción de callos en varios tratamientos con BAP o ANA-BAP y el establecimiento de suspensiones celulares en varias combinaciones de auxinas (AIA, ANA o 2,4-D) - citocininas (BAP o KIN). A partir de los callos formados se establecieron suspensiones celulares y estudió la acumulación de metabolitos secundarios. En ese sentido, en suspensiones celulare...

The Amazon rainforest is one of the most biodiverse and at the same time most threatened ecosystems in the biosphere. Its different habitats provide a unique floristic pattern. Therefore, we aimed to identify the floristic arboreal composition in an area of the Amazon rainforest and determine the local patterns of diversity in its different habitats. This study was conducted around the Tambopata Research Center, Madre de Dios, Peru. To achieve our goals, we established 20 (50 × 30 m) plots distributed equally in four habitats, these being: Mauritia Palm Swamp, Floodplain Forest, Successional Floodplain Forest, and Tierra Firme Forest. In each plot, we collected all individuals with a diameter at a breast height ≥ of 10 cm. Subsequently, the individuals were identified and classified by cluster and diversity analysis. We found 57 families, 173 genera, 300 species, and 1958 individuals....
