Pomegranate flower is bisexual flower primordium,abnormal ovule development forms functional male flowers,and normal ovule development flowers are bisexual flowers.Pomegranate ovules are inverted ovules with double integuments and thick nucellate.The formation of functional male flower is due to abnormal and stagnant development of ovule integument.Functional male flow-er typically drop and fail to set fruit.Thess result in flower and fruit dropping,low fruiting rate and loss of tree nutrients,which affects the yield and fruit quality of pomegranate.This review focuses on the study of pomegranate ovule development in recent years,including the morphoanatomy study of ovule development,endogenous hormones,the functions of INO,CRC,STK,and BEL1 tran-scriptional regulatory factors in pomegranate ovule development.
