Germinação de esporos de Polypodium pleopeltifolium: resultados preliminares

Polypodium pleopeltifolium is an epiphytic fern which occurs in cerrado vegetation of the State of São Paulo, Brazil. The species is light sensitive for germination but some spores germinate in the absence of light. Short treatments at 40 or 5ºC and alternating temperatures did not increase the germination in dark conditions. Germination was not affected by IAA but it was reduced by GA3, CEPA and ABA. Red light (short treatments) promoted germination.
