contents	Morfologia y estrategias reproductivas del gametofito de Polypodium lepidotrichum (Fée) Maxon (Polypodiaceae) I. Blanca Pérez García Irma Reyes Jaramillo Biología El gametofito joven de Polypodium lepidotrichum (Fée) Maxon es un filamento corto constituido por cuatro a cinco células; en una fase intermedia los gametofitos son espatulados. Los protalos maduros, formados alrededor de ocho semanas después de la germinación de las esporas, son cordiformes, reniformes u ovales con la base angosta. Se observaron gametofitos bisexuados yunisexuados. Los esporofitos jóvenes fueron evidentes después de doce semanas a partir de la siembra de las esporas. Se concluye que las estrategias reproductivas de P. lepidotrichum involucran fecundaciónintragametofítica e intergametofítica. 1994 artículo científico 0187-7151 https://www.redalyc.org/articulo.oa?id=57402806 es http://www.redalyc.org/revista.oa?id=574 Acta Botanica Mexicana application/pdf Instituto de Ecología, A.C.
