    Seed germination is the fundamental phenomenon that determines the successful growth and development of each plant species,even more so in Cinchona ofcinalis, which is a forest species that stands out for its medicinal importance. Te objective of thiswork was to determine the best sigmoidal mathematical model describing the germination of C. ofcinalis. For the germinationtest, a completely randomized design was used with six treatments and three replicates per treatment; 100 °C. ofcinalis seeds wereused per replicate, and 1800 seeds were needed in the trial. Gompertz sigmoidal, logistic, and von Bertalanfy models were used toanalyse the germination curves of C. ofcinalis. Te results of these adjustments were analysed based on the graphic representationand statistical criteria (Akaike’s value (AIC), R2 , and R2ai). Te results suggest that the Gompertz and logistic models havea better graphic representation, showing values close to those observed, while the von Bertalanfy model shows negative ger-mination values. According to the statistical criteria, the lowest AIC and the highest were obtained. R2 and R2ai with the Gompertzmodel, followed by the logistic model and von Bertalanfy. It is concluded that the Gompertz model can represent the shape of thegermination curves of C. ofcinalis for the six treatments of the test.

    Evolution and future perspectives of scientific journals in Peruvian public universities
    (Institute of Advanced Science Extension, 2023-10-19) Reategui Inga, Manuel; Morales Rojas, Eli; Fernandez Zarate, Franklin Hitler; Fernández Villarroel, Roger Álvaro; Ferro, Pompeyo; Alva Valdiviezo, Wilfredo; Ñique Alvarez, Manuel; Guerra Lu, José Kalión; Dávila Zamora, Edilberto César
    In Peru, scientific journals are in constant growth, as they seek to make visible the scientific work of licensed public universities. In this sense, the objective of this research was to evaluate the historical evolution and future perspectives of scientific journals in Peru. The research was carried out by reviewing the official web pages of each institution, taking into account the official list of universities authorized by the Superintendencia Nacional de Educación Superior Universitaria (SUNEDU). We reviewed journals that are included in the Sistema Regional de Información en Línea para Revistas Científicas de América Latina, el Caribe, España y Portugal (Latindex Catálogo 2.0), SciELO, Web of Science (WOS) and Scopus. Data analysis was performed by tabulation in Excel and Minitab 19. We found 205 scientific journals, 51 are indexed in at least one database (Latindex Catálogo 2.0, SciELO, WOS, or Scopus) and 154 in no database, which means that the editorial teams have an arduous task. Only four journals are indexed in Scopus (three belong to the Universidad Nacional Mayor de San Marcos and one to the Universidad Nacional de Trujillo). It is concluded that the evolution of the journals is a function of their Google Scholar H index. Likewise, support for public universities should be increased to promote the indexing of scientific journals to generate greater visibility of research at regional, national, and international levels of public universities in Peru. In this sense, future perspectives include incentive policies for researchers who publish in local journals.
