Mobilization of storage reserves duringCyathea delgadii spore germination

Short Communication


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.
