Re: Fern Life Cycle Rates

I have no hard information, but I've seen Anogramma chaerophylla as a pest in Dutch greenhouses, and I'm fairly sure that it has a much shorter cycle than 4 months.

To all,
I am currently working on a genetic mapping project in Ceratopteris and I am looking for some information on life cycle rates in other ferns.
Basically, what is the shortest time anyone has observed to get from spore to spore in a fern species? Ceratopteris richardii does it in about 120 days. I am interested in doing genetic work on something other than Ceratopteris (not the most handsome morphology), and I would need something with a relatively quick life cycle. But I am just curious about the shortest times people have observed, and if anybody has any tricks to speed life cycles up.
