Predicción in vitro del estrés de Vallisneria americana Michx. por enriquecimiento de iones amonio y nitrato

Abstract: El enriquecimiento de nutrientes es un factor de estrés involucrado en la declinación de vegetación sumergida. Sin embargo, la sensibilidad fisiológica o toxicológica de los genotipos varía debido a las interacciones microbióticas y el desbalance fisicoquímico del agua, las cuales han sido abordadas mediante una aproximación reduccionista y experimentos controlados. El objetivo del estudio fue evaluar, en un modelo de cultivo in vitro de Vallisneria americana, diferentes fuentes y concentraciones de N sobre la… Show more

“…A pioneering study, under semi-aseptic sterilization conditions, was carried out on numerous Begonia lines using non-sterilized explants of leaves (about 2.0 cm 2 in area), grown onto half-strength Knop's mineral salts medium and solidified with 1% agar, although with limited success and without reporting contamination rates (Bowes, 1990). In Vallisneria americana, a submerged and perennial hydrophyte distributed from North America to Central America, five experiments were carried out with stages of pre-sterilization, sterilization, and post-sterilization of explants and culture in monophasic or biphasic nutrient media; however, the results expressed in the regeneration-contamination balance were somewhat discreet (Ruiz-Carrera & Sánchez, 2008).…”
