Total Free Proline Estimated in Some Selected Species of Pteridophytic Flora of Rajasthan

Proline, a well-known amino acid, has been estimated in ten different pteridophytes, including Adiantum capillus-veneris L., Adiantum caudatum L., Adiantum incisum Forssk., Adiantum philippense L., and Actiniopteris radiata (Sw.) link. Christenh. in various organs such as the root, rhizome, and leaves Hemionitis anceps (Blanf.) Christenh., Hemionitis bicolor (Roxb.) Christenh., Hemionitis formosana Christenh (Hayata). Result of study is indicate that the maximum total proline in entire plant was recorded 43.54 mg/gdw and leaves have been recorded 24.10 mg/gdw in Pteris vittata subsp. vittata and the minimum value was recorded 3.60 mg/gdw in root of Adiantum caudatum L.
