Efectos de PCMB sobre Digitalis thapsi

Abstract

[ES] Como continuación de nuestras experiencias sobre acción mutagénisa del PCMB en Digitalis thapsi presentamos los resultados obtenidos en la segunda floración de plantas tratadas inicialmente en 1966, así como los datos correspondientes a las primeras observaciones de la F1, iniciadas en la primavera de 1968 y que muestran la eficaz y persistente acción de este agente para inducir variaciones fenotípicas transmisibles. También exponemos un avance de los nuevos estudios comparativos sobre acción mutagénica de PCMB y colchicina empleando concentraciones más bajas que las ensayadas anteriormente. En todos estos ensayos se pone de manifiesto la actividad mutagénica de ambos agentes para inducir notables variaciones fenotípicas aun aplicados a concentraciones débiles. Las observaciones iniciales hechas en CMP mostraron la existencia de algunas irregularidades meióticas, destacando la producción de tétradas con 3, y 6 núcleos.

[EN] We have continued our experiments about the mutagenic action of PCMB on Digitalis thapsi, and we report the results obtained in the second blossoming of plants originally treated in 1966. We present as well the data relative to our initial observations -started in the Spring of 1968- on F1, which show an efficient and permanent ability of PCMB to induce transmissible phenotypical variations. We also present and advance of our new comparative studies on the mutagenic action of PCMB and colchicine, both of which turned out to be active in the induction of remarkable phenotypical variations, even when used at lower concentrations than at those previously studied. Aur firts obervations on PMC showed some meiotic irregularities, the most striking of which were tetrads with 3,5 and 6 nuclei.
