Este número de Reseñas sobre Población y Desarrollo aborda el asunto de la reproducción en la adolescencia, que es prioritario en América Latina por los altos niveles que alcanza y por su relación bidireccional con la desigualdad social. El texto sintetiza hallazgos de un estudio en curso, realizado con el apoyo del UNFPA, sobre los niveles, tendencias, desigualdades sociales y determinantes próximos de esta reproducción en América Central. Se trata de la subregión con mayores índices de reproducción adolescente de América Latina, pero que, a diferencia de América del Sur, registra un tendencia relativamente generalizada a su baja. El análisis empírico, basado en el procesamiento de los censos y las encuestas especializadas más recientes disponibles en la subregión, se complementa con sugerencias de política, en particular en materia de intervenciones relacionadas con la educación sexual integral y con el acceso universal a la salud sexual y reproductiva mediante servicios adecuados para adolescentes.

The objective of this work was to evaluate the effect of calcium silicate and copper sulfate on anthracnose intensity and nutrition of bean plants. The experiment was conducted using an experimental design in randomized blocks following a 4 x 4 factorial arrangement, (four levels of calcium silicate and four levels of copper sulfate) and two additional treatments (plants without inoculation and plants sprinkled with Benomyl). Four evaluations of the incidence and severity of anthracnose were done, in addition to measuring total leaf area. At the end of the evaluations, incidence and severity data were integrated over time, obtaining the area under disease progress curve (AUDPC). Contents of N, P, K, Ca, Mg, B, Cu, Fe, Mn, Zn, Si and lignin were determined in the aerial part. A linear decrease of the intensity AUDPC was observed with the increase of the doses of calcium silicate. The severity AUDPC was influenced by the doses of copper, obtaining a reduction of 35% on the higher dosage. The supply of silicon and copper altered the content of the K, Mg, S, Zn, Ca and Si in the aerial part of the bean plants.

The objective of this study was to evaluate the effect of different sources and doses of copper (Cu) applied to leaves on growth and nutrition of coffee seedlings. The treatments consisted of combinations of two Cu sources (Cupric Sulfate Ammonium - CSA and Copper Sulfate - CS) and four Cu doses (0, 250, 500 and 1000 g ha-1). The sources of Cu in different doses were dissolved in water, calculated for the application volume of 400 L ha-1. The doses were divided in 3 applications at 20 days. The Cu content and concentration in the leaf, stem, and root in were measured. The dry matter of the leaf, stem, root and total and the utilization, absorption and translocation efficiency, in coffee seedlings were evaluated. In general the Cu content and concentration were obtained for the CS at doses of 250, 500 and 1000 g ha-1 Cu. The maximum increase of total dry matter was 48 and 51 g to CSA and CS, when applied 534 and 668 g ha-1, respectively. The highest utilization and absorption efficiency was found to CSA and CS, respectively. The translocation efficiency was similar for both sources.
