Control de la apogamia en el helecho Dryopteris affinis ssp. affinis a través del cultivo in vitro

Abstract

En el helecho Dryopteris affinis ssp. affinis, tiene lugar un proceso denominado apogamia, por la cual se omite la fase de intercambio de gametos en el ciclo sexual típico, desarrollándose un embrión partenogenéticamente, de manera espontánea. En el presente trabajo, se estudió el efecto de fitohormonas (AIA, GA3, IBA y BA), e inhibidores (Flurprimidol y TIBA), la fuente de carbono: sacarosa, y la intensidad lumínica, sobre dicho proceso. Asimismo, se ensayaron algunos protocolos de crioconservación con la espora y el gametófito. A la hora de cuantificar la expresión apogámica, medimos al microscopio óptico los gametófitos y embriones de D. affinis tras 50 días. Con las medidas obtenidas se realizan análisis estadísticos ANOVA y χ2. Pudimos llegar a ver en D. affinis que la apogamia persistía en todos los tratamientos, solo había una cierta disminución en flurprimidol 3 mM, sacarosa 29 mM, mientras que en IBA llegó a desaparecer. Además, en este trabajo se vio que es posible crioconservar esporas de ésta especie sin problema.
