اثر استرس شوري و خشكي در تغيير فعاليت اسيد فسفاتاز درگالوس يونجه

Effect of salt and drought stress on acid phosphatase activity in alfalfa (Medicago sativa L.) callus

Acid phosphatase is widely found in plants. This enzyme has and extra cellular activity .For instance. salt and drought stress increase its activity. Alfalfa is a plant can be used for production of resistant callus to salt and water stress.When calli were cultured to the medium containing 0,2,4,6,8,10% mannitol and 0,0.2,0.4,0.6,0.8, 1 % NaCl,in both cultivars (Yazdi and Hamedani) the activity of acid phosphatase increased.Cultivar Hamedani showed low activity while cultivar Yazdi had high activity of enzyme.Results showed that activity of acid phosphatase is dependent on genotype.
