title: [Comparative study on the erect and fallen types of Platycodon grandiflorum (Jacq.) DC].
abstract: Based on botanica characters, phenophase, yield and content of active constituents, the erect and fallen types of platycodon grandiflorum were compared. The results show that the comprehensive characters of erect type are better than those of fallen type and the erect type is therefore good for popularization. Some specific characters of the fallen type are better than those of the erect type, and the fallen type is therefore to be preserved as one of the germ plasm resources.
