| 摘 要： | 采用石蜡切片法对柃木（Eurya japonica Thunb．）插条不定根的形成进行了解剖学研究。观察结果表明，柃木插条不定根原始体为诱生根原始体；不定根原基起源于维管形成层与髓射线的交叉区域。插条的韧皮部存在较连续的排列成环状的厚壁纤维细胞，茎内无生根原基。柃木插条的这些结构特征可能与柃木插条生根率低有关。 |

| Abstract: | Anatomical study on rooting of Eurya japonica Thunb. cutting has been carried out by the paraffin section method. The observation result shows that the adventitious root primordium of E. japonica cutting belongs to the type of induced root primordium. The adventitious root primordium originates from the cross region of vascular cambium and pith rays. There are cyclical and continuous arranging sclerenchyma cells in phloem, and no root primordium in stem. These structure features might be related to the low rooting rate of E. japonica cutting. |
| Keywords: | Eurya japonica Thunb. cutting adventitious root anatomy |
