Morphological Investigation and Classification Research of 18 Bougainvillea

To explore the genus Bougainvilleaclassification criteria, comparative analysis of 15 morphological traits collected 18 varieties of Bougainvillea, in order to provide a reference for the promotion of Bougainvillea cultivation, breeding and classification, identification and other research. Q-type clustering results showed that 18Bougainvillea varieties can be divided into 3 categories, including twosmaller groups and alarger groups, to a certain extent, has been clear about the relationships between species. This study identified some of morphological traits important for Bougainvillea classification and germplasm identification application.
