Abstract: The differentially expressed characteristics of tissue culture plantlets with different explants were studied in Dendrobium officinale. 1000 cultivated Dendrobium officinale plantlets with different regeneration pathways were randomly and respectively selected for morphological investigation and classification. The results showed that the cultivated Dendrobium officinale plantlets which using stem segments as explants performed highly consistent in their morphological characteristics; but the plantlets which were cultured by seed embryo as explants performed variedly. So, it followed that using seed embryo as explants for Dendrobium officinale breeding could effectively broaden their germplasms resources.
