| 摘 要： | 国内外重要的植物分类学与系统学文献均认为:木犀科和属(白蜡树属)植物只有2心皮的子房和果实。目前仅有2篇文献认为木犀科和属植物还具有3或3和4心皮的子房。作者在对属植物的果实进行研究时,发现属植物果实具有2心皮、3心皮、4心皮和6心皮4种类型,首次发现了属植物具有6心皮的果实。这一发现具有一定的系统学意义。

| Abstract: | The most famous and important works of Taxonomy and Systematics in the world only recognized the ovary is of 2-carpel in the genus Fraxinus and the family Oleaceae. Sun San-sheng (1985) and Wang Guang-qing et al.(1987) thought the ovaries is also with 3 carpels and even 4 in Fraxinus. But their papers were ignored. Four types of fruits, collected in Beijing and Zhengzhou in China, of F. pennsylvanica Mars. var. subintegerrima (Vahl.) Fern. and other species are found in 2001-2004. It can affirm that there are four types of ovaries: 2-carpel, 3-carpel, 4-carpel and 6-carpel in Fraxinus. The 6-carpel ovary in Fraxinus and Oleaceae is found for the first time. |
