[ 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.展开更多
