Abstract

Tiller leaf anatomical features of nine Alopecurus species collected from high mountainous areas in Turkey were evaluated in the present study. Detailed leaf anatomical descriptions of the studied taxa and an identification key generated using the anatomical features are given. Clustering and principal coordinate analysis (PCA) methods were applied based on a total of 14 leaf anatomical characters. Anatomical differences between species were detected and anatomical characters of taxonomic interest were identified in this genus. With clustering analyses, a UPGMA tree was obtained to show the relationship between the species studied. Based on the results of PCA, the arrangement of adaxial sclerenchyma cells, the number of adaxial ribs, the number of abaxial sclerenchyma strands, the size of epidermal cells and the number of vascular bundles are designated as the most reliable characters to separate the species.

石竹属(禾科)叶片解剖特征的分类学意义
本研究对从土耳其高山地区采集的9种Alopecurus的分蘖叶解剖特征进行了评价。给出了所研究分类群的详细叶片解剖描述和使用解剖特征生成的识别密钥。基于14个叶片解剖特征,应用聚类分析和主坐标分析方法。在该属中发现了物种之间的解剖学差异,并确定了具有分类学意义的解剖学特征。通过聚类分析,得到了一个UPGMA树来显示所研究物种之间的关系。根据主成分分析结果,近轴厚壁组织细胞的排列、近轴肋的数量、远轴厚壁细胞链的数量、表皮细胞的大小和维管束的数量被认为是分离物种最可靠的特征。

期刊介绍: The interest of the journal is field (terrestrial and aquatic) and experimental botany (including microorganisms, plant viruses, bacteria, unicellular algae), from subcellular level to ecosystems. The attention of the Journal is aimed to the research of karstic areas of the southern Europe, karstic waters and the Adriatic Sea (Mediterranean).
