Abstract

The majority of spores ofCyathea delgadii germinate during the first seven days after imbibition under constant white light. The fresh weight remains constant from day 0 to day 7, but the dry weight decreases. Lipids constitute about 43% of the weight of spores (day 0). There is a drastic reduction in the amount of lipids from day 0 to day 14. Proteins, soluble sugars, reducing sugars and starch increase from day 0 to day 14.
