Abstract :

Algae are known to contain different bioactive compounds. In present research work, extracts in different solvents, of green alga Spirogyra jugalis (Fl. Dan.) kuetzing, have been used to study their effects on tomato seeds. Cold water and hot water extracts have shown stimulatory effects in germination and development of shoot and root. Algal extracts prepared in acetone methanol, toluene also shown stimulatory effects. Extract prepared in petroleum ether did not favoured seed germination. Use of cold water and hot water extracts can be recommended to farmers as a ecofriendly practice for better germination and growth. Present research work reveals that green alga Spirogyra jugalis contain certain growth promoting substances which enhances seed germination.
