Primary and secondary metabolites produced during different seasons and physiological stages in Shankhapushpi (Convolvulus microphyllus)

The present study was undertaken to examine the synthesis of various metabolites such as leaf pigments, proline, osmotic potential (OP), crude protein, phosphorus, alkaloids and phenols during different seasons and physiological (growth) stages in Convolvulus microphyllus. Leaf pigments, proline, total alkaloids and phenols were maximum in summer season during flowering stage. Winter season was most favourable for maximum phosphorus and crude protein during seedling and flowering stages, respectively. Maximum total sugars were observed in rainy season during seedling stage.
