Abstract
:
The effect of ultrasonic waves on seed germination, nucleic acid contents as well as growth regulators of peanut seedlings were carried out. The data obtained showed that, ultrasonification has affected seed germination as well as water content of peanut, that lowest percentage of germination and water content were obtained at short exposure to ultrasonic waves (15 minutes). The DNA and RNA contents were decreased by ultrasonic waves especially at long exposure (60 minutes). Ultrasonification of peanut seedlings induced a marked reduction in cytokinin activity. At long exposure (60 minutes), auxin content of peanut seedlings showed marked increasing in treated seedlings as compared with untreated until 72 hours. However, gibberellin contents showed verse manner as that of auxin, thus short exposure (15 minutes) recorded the highest values until 72 hours.
