Abstract：Seedless fruits are especially appreciated by consumers because of their high edible rate, good taste and their convenience. Seedless is a desirable economic trait for fruits and an important index in breeding work. Seedless fruits can be obtained through parthenocarpy which the ovary develops without fertilization and by stenospermocarpy which the ovule is fertilized but the seed is aborted for lots of reasons. In this paper, we reviewed the potential roles and underlying mechanisms of auxin, gibberellin, cytokinin and ethylene, and analyzed the crosstalk of different hormones during the set and development of fruits.
