Abstract

The role of different temperatures on the germination of spores of five species of Cyatheaceae is analyzed in this paper. Lophosoria quadripinnata and Trichipteris bicrenata have the widest tolerance to extreme temperatures, while Trichipteris scabriuscula has a reduced range of tolerance. The results show that a rough correlation can be established between the temperatures where the species grow best and its general distribution in America.
