ABSTRACT:

The aim of the present study was ex situ conservation and developmental biology of Pteris vittata L., observed in natural conditions. The complete observation of spore structure, germination, development of different stages of gametophyte and sporophytes of P. vittata L., were identified in microscopically. Results reveal that observed in microscopically, spores of P. vittata were easily germinated and life cycle of gametophyte to sporophytes stages identified and it was easily adopted on the natural conditions.

 

Keywords: Pteridophytes; pteris vittata, gametophytes, sporophytes, spores, germination

ABSTRACT: The present study describes the Pteridophytic flora of the Bhandara district. The area was surveyed in different seasons during the years 2009 to 2012. Total of 34 species of ferns and fern allies belonging to 21 genera and 19 families were recorded. Some possible threats to further survival of these are identified and highlighted.

 

Keywords: Pteridophytes, Bhandara district, ferns and fern allies.

ABSTRACT:

The present study was exploration of pteridophyte species of Alutha kanni river, Tenkasi, Tirunelveli district, Tamilnadu. The results of field study observed by 6 species of pteridophytes have been collected and identified. The pteridophytes species of Azolla pinnata R. Br., Marsilea minuta L., Salvinia molesta D.S. Mitch, Nephrolepis multiflora (Roxb.) F.M.Jarret ex C.V.Morton (syn. Davallia multiflora Roxb.), Adiantum capillus-veneris L., and Pityrogramma calomelanos (L.) Link was first time reported in the river of Alutha kanni, Tenkasi, Tirunelveli district, Tamilnadu.
