摘　　要：Endogenous levels of UVAC in different parts of matured gametophytic blades of Porphyra haitanensis and the effect of exogenous UVAC on sporangial branchlet formation are studied. The UVAC value in vegetative (36. 78 mg/g) and reproductive (29.25 mg/g) parts of female thallus is higher than their counterparts in male thallus (34.68 mg/g and 20.46 mg/g). The UVAC value of reproductive parts is higher than vegetative parts of same sexual thallus. The optimal UVAC concentration for sporangial branchlet formation is 0.1 mg/g.Endogenous levels of UVAC in different parts of matured gametophytic blades of Porphyra haitanensis and the effect of exogenous UVAC on sporangial branchlet formation are studied.
