摘　　要：The effects of amylase activity in calli of sweet potato on different concentration of abscisic acid（ABA）,gibberellin（GA3） and sugar were investigated.As a result,ABA always showed the advance to amylase in a range of concentration of sucrose.Otherwise,the regulation of GA3 to activity of amylases was changed by different concentration of sucrose.Lower or higher concentration of sucrose both inhibited the activity of amylases.And the regulation of sucrose to amylases was not effected with supplementing ABA or GA3.The effects of amylase activity in calli of sweet potato on different concentration of abscisic acid （ABA）, gibberellin（GA3） and sugar were investigated.
