| 摘 要： | 利用常规石蜡切片法，系统研究了广藿香不定根的起源和发育。观察结果表明：广藿香茎中没有先成根原始体，其不定根属于诱生根类型，起源于靠近维管形成层的初生韧皮部薄壁细胞中，愈伤组织内无不定根生成。本研究揭示了广藿香扦插生根的解剖学特征，从而为该药材在生产中提高扦插育苗成活率提供理论依据和实践指导。

| Abstract: | With the traditional paraffin section method,the initiation and development were systematically studied.Our observation reveals that no pre-formed adventitious roots exist in the stems of Pogostemon cablin ,all adventitious roots,formed in the cutting,belong to induced roots,which originate from the nascent phloem parenchyma cells,no adventitious roots were found to formed in callus.The research results shall provide the time and position of initiation and the character of development for the introduction of adventitious roots in cuttings of Pogostemon cablin ,further facilitate the production of traditional Chinese medicine " Pogostemon cablin ". |
