Bougainvillea with long flowering period， large amount of flowers， strong resistance and various forms of application， has become the fastest growing woody flowers in southern China of sunrise flower industry. With the improvement of horticultural technology and the expansion of international germplasm exchanges， the number of Bougainvillea varieties is continuously increasing. However， the cases of homonym and synonym in Bougainvillea brought considerable difficulties to the collection and preservation of resources. Xiamen Botanical Garden， as the national Bougainvillea germplasm resource center， has initially built an information management system and service platform based on B/S model and using modern management information system， achieving efficient management of the germplasm resource bank. This paper introduces the platform architecture， database design， technology realization and platform function composition in detail. Through improving the efficiency of information management， we aim to promote the collection， protection， research， evaluation and application of germplasm resources of Bougainvillea. In addition， the design and development concept of the platform can also provide reference for the construction of information management systems and service platforms in other flower.
