摘　　要：[ Objective] This study aimed to investigate the differences in morphological characteristics of Dendrobium officinale plantlets propagated from different explants. [ Method] Randomly 1 000 D. offtcinale plantlets propagated via different regeneration pathways were selected for morphological investigation and classification. [ Result] D. officinale plantlets propagated from stem segment explants exhibited highly consistent morphological characteristics, while those propagated from seed explants exhibited a variety of morphological characteristics. [ Conclusion] Therefore, using seed explants for regeneration can effectively broaden the germplasms resources of D. officinale.[ Objective] This study aimed to investigate the differences in morphological characteristics of Dendrobium officinale plantlets propagated from different explants.
