Summary: | ABSTRACT Present study is aimed to investigate the effect of seasonal changes on the storage compounds i.e. free amino acids, RNA, proteins, carbohydrates alongwith enzymatic activities in three species of leafy liverworts, namely Chiloscyphus gollani Steph. , Solenostoma crenulata (Sm.) Steph. and Fossombronia himalayensis Kash. Activities of enzymes α-amylase, β-amylase and invertase were found to be reducing towards the end of the growing season i.e. January-March. This is correlated with the accumulation of carbohydrates in the plant body in this season. The content of free amino acids coupled with the highest activity of enzyme protease was found on peak in the rainy season i.e. July-September. The maximum value of proteins was observed in the winter season i.e. October-December and the content of protein is found to be inversely proportional to the content of free amino acids. Key Words: Seasonal changes, Chiloscyphus gollani, Solenostoma crenulata , Fossombroniahimalayensis , inverse relation. REFERENCES Asakawa, Y. 1999.
