Abstract
Pongamia pinnata is one of the commercially important tree species, which provides seed oil utilized in the production of bio-diesel. Seeds of this species were subjected to different osmotic potentials induced by polyethylene glycol (PEG-6000) in order to study their response to drought conditions. Seeds were germinated in petriplates at osmotic potentials 0, -0.2, -0.5 and -0.8 MPa. Germination at high level of water stress was inhibited, but the recovery of their germinability after transferring to distilled water was high in all cases except -0.8MPa. The root length, fresh weight, dry weight, relative water and protein contents showed a significant decrease than their corresponding controls. However, carbohydrate and proline contents in the water stressed seedlings showed a significant increase.
