Abstract: The alteration of amylase' activity was found distinctly when calli were treated with different concentration PEG6000.Under the low concentration PEG(05%、1%),the scope of amylase' activity was changed a little.On the contrary,when calli were treated with higher concentration PEG the activity of amylase was altered in wide scope.This consequence reveals the PEG regulation about expression of amylase in calli of sweet potato.
