摘要

本文研究了显微绿藻Pediastrum s.l的壁超微结构变异性，并讨论了其作为诊断特征的价值。用光镜和扫描电镜对21个分类群的田间和培养材料进行了比较。用LM和SEM显微照片记录了小檗表面的9个超微结构元素。最多的分类群表现为网状纹饰，由三角形网和位于其角上的颗粒组成。本文考虑利用壁面超微结构来调和小檗品种的传统和现代分类系统，并讨论代表不同品种的品系之间的系统发育关系。

Phenotypic plasticity of wall ultrastructure in the green alga Pediastrum s.l. (Chlorophyta, Sphaeropleales)

This study examined wall ultrastructure variability in the microscopic green alga Pediastrum s.l. Its value as a diagnostic character is discussed. Field and cultured material of 21 taxa were compared using light and scanning electron microscopy. Nine ultrastructural elements occurring on the surface of Pediastrum are documented with LM and SEM micrographs. The highest number of taxa showed reticulate ornamentation composed of a trigonal mesh and granules situated on its corners. The paper considers the use of wall ultrastructure to reconcile traditional and modern taxonomical systems with regard to Pediastrum varieties, and addresses the phylogenetic relationships between strains representing different varieties.

期刊介绍： Polish Botanical Journal is an international journal publishing original papers covering various aspects of vegetation science, plant and fungi biodiversity, biosystematics (including plant anatomy, cytology and embryology), phytogeography, evolution and ecology. All papers are considered by at least two reviewers. Polish Botanical Journal is issued twice per year. The two issues form one annual volume.
