In Vitro Studies on Gametangial Ontogeny and Development of Gametophyte of Homosporous Fern- Dryopteris chrysocoma

In the present study spores of were cultured in P & T medium and 67.47% and spore germination was Dryopteris chrysocoma recorded within a week of sowing.Spore germination was found to be Vittaria Type.The viability of spores was lost in ten months, when kept in room temperature (20-25C).Prothallial development was Aspidium Type.In vitro culture creates a new path for mass cultivation of ferns and will be very helpful for their restoration and conservation.This work advances our knowledge of the pteriodophytes reproductive capacity, enabling us to better preserve, restore, grow, and protect them.
