The floral morphology and flowering characteristics in Camptotheca acuminata Decne were investigated.Breeding system was characterized by outcrossing index(OCI),pollen-ovule ratio(P/O),and the outcome of bag test and artificial pollination experiment.The results showed that the inflorescences of C.acuminata were cymes,each of which was composed of 4~6 capitula.Within a cyme,the 3~4 distal capitula were composed of hermaphroditic florets,while the 1~2 proximal capitula were composed of male florets.There wer...
