The design included five experiments with stages of presterilization or washing with 0.1% Tween 20 R®, sterilization with NaClO and poststerilization of explants(leaf base, rhizome, caulinar apex and seeds), and culture in monophasic or biphasic nutrient media. Leaves and rhizomes were sterilized with 0.3 and 0.6% NaClO, and contact times of 2.5 and 5 min. Both explants cultured in gellified monophasic White medium with 58.4 mM sacarose and a pH of 7.5 presented on average a 60% contamination by translucid lipidic exudates, followed by darkening. The presterilization of leaves and rhizomes caused the production of exudates, and the addition of 0.01% ascorbic acid to the nutrient medium caused its inhibition. Comparing theWhite medium with the 0.5 MS medium, both with 0.88 x 10ֿ³ mM of bencyladenine, asepsia of explants was improved in White and leaf pigmentation was significantly favored in 0.5 MS, although no explant presented regeneration. Presterilization was omitted in the experiments with caulinar apices and seeds, and sterilization was carried out with 0.6% NaClO for 15 min... 2008 artículo científico 0186-2979 https://www.redalyc.org/articulo.oa?id=15424305 en http://www.redalyc.org/revista.oa?id=154 Universidad y Ciencia application/pdf Universidad Juárez Autónoma de Tabasco Universidad y Ciencia (México) Num.3 Vol.24 |
