El tipo de gelificante en el desarrollo in vitro y la aclimatizacion de plantas de Yampi (dioscorea trifida) y ñame (dioscorea alata) Ana Gabriela Chacón Roberto Valverde Francisco Saborío Luis Gómez Sergio Torres Agrociencias name yampi in vitro gelificante aclimatizaci6n El yampf y el name se cultivan en ~ostaRica primordial mente con fines de exportaci6n;sin embargo, su producci6n se ve seriamente li-mitada por la falta de semilla libre de plagas yenfermedades. La producci6n in vitro de semillarepresenta una altemativa a esta problematic a,pero este proceso debe a su vez ser optimizado.El presente trabajo evalu6 el efecto de 2 gelifi-cantes sobre el crecimiento in vitro y en invema-dero de plantas de D. trifida y D. alata. Se en-contr6 que, en general, el crecimiento in vitro yen invemadero de las plantas se ve favorecido enambas especies por el uso del Phytagel@ a 1.3 y1.8 g/L. Ademas, el subcultivo de plantas de D.alata con sfntomas de hiperhidricidad en mediosolidificado con agar redujo considerablementeestos sfntomas. 2000 artículo científico 0377-9424 https://www.redalyc.org/articulo.oa?id=43624206 es http://www.redalyc.org/revista.oa?id=436 Agronomía Costarricense application/pdf Universidad de Costa Rica Agronomía Costarricense (Costa Rica) Num.2 Vol.24
