Abstract
Filmy ferns can desiccate and recover after rehydration to resume photosynthesis. Slow and fast desiccation rates were compared in filmy fern fronds to determine whether structural or physiological differences may occur between desiccation rates. Slow desiccation is considered to be more similar to natural conditions experienced by plants that grow under the forest canopy. A fast desiccation rate will help to understand whether slow desiccation is important for recovery and viability.
