摘要
运用细胞图象分析系统及显微照相的方法对台湾青枣Z iziphus mauritiana次生木质部导管分子进行了观察研究。在台湾青枣的次生木质部导管分子中存在着许多不同的样式,并且导管分子穿孔板存在着3种类型:两端均为一个单穿孔板;一端为一个单穿孔板,另一端为梯状穿孔板;具纤毛的单穿孔板。分别对其进行了描述,并从导管分子个体发育与系统发育的角度进行了讨论,认为3种类型的穿孔板为导管分子穿孔板的系统演化提供了新的证据。
The vessel dements of secondary xylem in Ziziphus mauritiana was observed by bio-microscope image analysis system and micrography. The results show that there are various patterns of vessel elements and three types of perforation plates： both ends of the vessel element aresimple perforation plate; one end is simple perforation and the other is scalariform perforation; the simple perforation with cilia in Z. mauritiana. It is discussed that the ontogeny and phylogenesis of vessel elements in Z. maudtiana. The new evidence was provide on the phylogenesis of perforation.
