摘要: 对青荚叶[Helwingia japonica(Thunb.)Dietr.]和万寿竹[Disporum cantoniense(Lour.)Merr.]的形态观察和解剖研究,结果表明:1)青荚叶叶上开花现象是由植物遗传上的原因引起的,花或花序的发生位置在叶片的中脉上,而不是在叶腋;2)万寿竹的花序着生位置以发生在合轴分枝的主枝顶端给予了较合理的描述。本文还对国内有关文献上对节外生枝和叶上开花现象在描述上出现的分歧进行了分析和适当的订正。

Abstract: The morphological observations and anatomical studies on the extra-node branching and flowering on the blade of Helwingia japonica(Thunb) Dietr. and Disporum cantoniense(Lour.)Merr. were made in the present paper. It was indicated that 1)flowering on the blade of H. japonica resulted from the genetic characters, and flower and inflorescens developed from the main veins, not from leaf axillary; 2)the reasonable discription of growing position of inflorescens of D. cantoniense should be grown in sympodial branching. This paper also analysed the causes of explanational differences in Chinese literrature on these two phenomena and gave some revisions.
