Bajo la influencia de manipulaciones severas, cuyo objeto fue la desinfección del material vegetal, y de una mínima cantidad de moléculas carbonadas como fuente de energía en el medio de cultivo, se han obtenido callos friables, a partir de cotiledones etiolados de tres días de edad, de Pinus elliottii. Aparentemente se habrían obtenido yemas caulinares, que murieron al ser desinfectado el tejido. No se sabe si las yemas degeneraron a tejido calloso, o si el callo fue inducido a partir de tejido cotiledonar sin diferenciar, debido a las drásticas condiciones a las que fueron sometidos los cotiledones.
Callus tissue was obtained from Pinus elliottii ethiolated cotyledons, excised from a 3 days old embryo, under the ínfluence of severe conditions created to prevent fungí contamination and a minimum amount of a carbon source molecule in the culture media. The origin of the callus tissue was uncertain. lt could have been formed from caulinar buds differentiated on the cotyledon, or from the cotyledonar tissue itself, induced by the dreadful conditions needed to maíntain aseptic conditions in the culture environment.
