Abstract :

<p>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.</p>
