Abstract

La optimización de una tecnología constituye un aspecto importante para la factibilidad de su aplicación a gran escala. Se realizó un estudio para conocer la posibilidad de reducir en tiempo o eliminar la fase de maduración in vitro de los brotes de henequén, unido a su enraizamiento ex vitro con vistas a optimizar la tecnología cubana desarrollada recientemente (Peña et al., en prensa). Se demuestra que la incubación de los brotes desarrollados, una vez obtenida su multiplicación, pueden transferirse directamente a sustrato si se incuban durante 24 horas a 22 °C en soluciones de auxina. Se demuestra que el tratamiento con 75 mg/L de AIB proporciona la mejor respuesta. Se discuten los resultados. Technological improvement is important to analyze factibility for large scale application. Research to know the possibility of reducing time or eliminate maturation phase of henequen shoots, edded to ex vitro rooting in order to improve the recently develope technology in Cuba was conducted. Shoots incubated during 24 hours at 22 °C in auxin solutions result in the possibility of transfering full developed shoots after multiplication to substrate conditions. A treatment with 75 mg/L gives the best response. Results are discussed.
