Ceratopteris Fern Growth and Analysis: Observing Germination and Effects of Ammonium Nitrate Treatment

I: Abstract

Observing the effects of ammonium nitrate has on the germination days of C-Fern gametophytes by constructing an experiment with two spore-sown petri dishes, one control and one treatment – a normal nutrient-rich agar petri dish and an ammonium nitrate-containing petri dish respectively. The two petri dishes were each inoculated with three drops of spore suspension by a pipet, then spores were spread by a sterilized-bent paper clip to allow even distribution of spores. Gametophyte germination occurred approximately two weeks after inoculation for the control, and gametophyte germination occurred
