摘要
本研究调查了安纳托利亚东南部地区发现的两种马鞭草的解剖学、古植物学和种子微形态特征。sinuatum subsp.在光学显微镜下观察分类群的根、茎和叶的横切面,进行解剖研究。木质部成分在根的分类中起着重要作用。在茎的切片中,髓区是一个宽阔的区域,表皮细胞的上部被一个明显凹陷的角质层包围。叶片的主脉以开放的侧脉束为代表。adenosepalum 的花粉粒呈三孢子三胞形、球状,并有网状外皮装饰。sinuatum var. sinuatum 的花粉粒也是三孢子三胞形、扁球形,并有网状外皮装饰。sinuatum subsp. sinuatum var. adenosepalum 和 V. sinuatum subsp.种皮的装饰由不规则的多角形细胞组成,细胞内有明显而密集的液泡。本研究调查了一些性状在马鞭草品种划分中的重要性。为了支持下属分类中的祖先特征并帮助属的系统学研究,可以应用一些通常与花粉和种子微形态和解剖形态有关的特征。
Comparative Anatomy, Pollen and Seed Morphology of Two Verbascum Varieties (Scrophulariaceae) and Their Taxonomic Significance
In this study, the anatomical, palynological, and seed micromorphological traits of two Verbascum types found in the Southeastern Anatolia Region were investigated. V. sinuatum subsp. sinuatum var. adenosepalum Murb. and V. sinuatum subsp. sinuatum var. sinuatum L. are these variation. Cross-sections from the taxa's roots, stems, and leaves were viewed under a light microscope for anatomical study. The xylem components play a significant role in the taxonomic root portions. The pith area is a broad region in stem sections, and the upper portion of the epidermis cells is encircled by a distinct indented cuticle layer. The leaves' primary vein is represented by open collateral bundles. Pollen grains in Verbascum sinuatum subsp. sinuatum var. adenosepalum are tricolporate-tricolpate, prolate-spheroidal, and have reticulate exine ornamentation. Similarly, pollen grains in V. sinuatum subsp. sinuatum var. sinuatum are tricolporate-tricolpate, prolate, and have reticulate exine ornamentation. The brown seeds of V. sinuatum subsp. sinuatum var. adenosepalum and V. sinuatum subsp. sinuatum var. sinuatum have an alveolate, deep and wide posterior region, a truncated beak, and a prismatic-oblong shape. The ornamentation of the seed coat is made up of irregular polygonal cells that have noticeable and dense vesicles. The importance of a few traits in the Verbascum variety delimitation has been investigated in this study. For the purpose of supporting ancestral traits in the infrageneric classification and helping with genus systematics, some pollen and seed characters which are typically connected to pollen and seed micromorphological and anatomical patterns can be applied.
