Huamanripa (Senecio calvus Cuatr.) es una de las especies medicinales de uso frecuente por el poblador andino gracias a su propiedad antitusígena; sin embargo, los estudios para su preservación son muy escasas. Esta investigación tuvo como objetivo evaluar el efecto de cuatro dosis de ácido naftalenacetico (ANA) y ácido giberélico (AG3) en el enraizamiento in vitro y aclimatación en condiciones de invernadero. Se diseñaron dos ensayos, en el primero de ellos, el enraizamiento in vitro, se realizó en medio basal MS (Murashige y Skoog, 1962) a mitad de sales suplementado con 1; 1.5; 2 y 2.5mg/L de ácido naftalenacetico (ANA) y ácido giberélico (AG3) con las mismas dosis, para ello se empleó el diseño completamente al azar con cinco tratamientos incluyendo el testigo y veinte repeticiones, para la aclimatación en invernadero se utilizaron las plántulas procedentes del enraiz...

In vitro propagation of Senecio calvus was carried out as an alternative for its conservation. The buds were disinfected with HgCl2 (0.01 and 0.1%) with and without periodic addition of antibiotics. Murashige and Skoog culture medium (1/2) plus 2% sucrose and 0.3% phytagel 0.3%, and pH 5.7 was supplemented with benzylaminopurine for multiplication; while for the rooting naphthaleneacetic acid or gibberellic acid were used. Treatments without growth regulator were added. For acclimation two natural substrates were evaluated. The highest percentage of disinfection was obtained with 0.1% HgCl2 for 5 minutes adding rifampicin (72 μg·mL-1) and nystatin (200 μg·mL-1) every three days per 18 days. Benzylaminopurine increased the survival of the introduced buds and the percentage of shooted plants; however the number of shoots per plant did not show significant differences. Gibberellic acid ...
