Abstract

Some 45% of the Hawaiian pteridophyte flora were examined for mycorrhizae. VAM were present in 66 of the 89 species examined. Nonmycotrophy was significantly higher in Hawaiian pteridophytes than in non-Hawaiian pteridophytes. The highest mycorrhizal colonization occurred in the leptosporangiate families Dicksoniaceae, Dryopteridaceae, and Lindsaeaceae. Mycotrophy was lower in the eusporangiate families. Substrate strongly influenced the presence of mycotrophy. Mycorrhizae were present in 83% of terricolous species, in 86% of epilithic species, in 55% of epiphytic species, and absent from aquatic species. -from Authors
