Effect of Drought Stress on proline content of rice seedlings
The proline contents of rice seedlings of Jinyou 117 were measured at 4, 5, 6, 7 and 8 days after stopping watering under laboratory sand culture conditions. The results showed that the proline contents of rice seedlings increased after drought stress and reached their peaks at six days, and their growth rates subsequently slowed down and became stabile gradually. Whereas, without drought stress, the proline contents of rice seedlings were at low level and changed insignificantly throughout the observed time. Therefore, the accumulation of proline of rice seedlings under drought stress may be a physiological response to adaptation of drought condition.
