Use of PECTIMORF and BIOBRAS-16 in somatic embryogenesis of potatoes
Journal Title: Biotecnología Vegetal - Year 2002, Vol 2, Issue 1
Abstract
With the application of PECTIMORF and BIOBRAS-16, somatic embryos were obtained in potato (Solanum tuberosum, L) c.v. Desirèe, of 40 days old callus obtained from stem micropropagated plants. These were used as possible substitutes for crop regulators used in culture media for the induction of somatic embryos. The culture media was composed for 10ml.l-1 of Murashige and Skoog salt, 0.1mg.l-1 ANA, 0.1mg.l-1 kinetin, 0.5mg.l-1 thiamine, 2.5mg.l-1 cistein, 100mg.l-1 mioinositol, 20g.l-1 sucrose and 2.0g.l-1 agar. Four culture medias were tested in distinct combinations that contained different concentration of PECTIMOR and BIOBRAS-16 as substitute of auxins and cytokinins. After 90 days, the results obtained showed the possibility of substituting the auxins (0.5mg.l-1 ANA) and the cytokinins (0.5mg.l-1 kinetin) in the culture media, because the application of PECTIMORF at 3.2mg.l-1 and BIOBRAS-16 at 1.0mg.l-1, gave friable callus, high fresh weight (more than 1.4g) and a brownish color at the end of the process, moment in which the somatic embryos of different phases, appeared at the surface of the callus.
