摘要

本文研究了土耳其毛茛科飞燕草属(Delphinium L.)特有种Delphinium cilicicum P.H. Davis & Kit Tan和D. petrodavisianum İlarslan & Kit Tan的形态学、解剖学和孢粉学特征。D. cilicicum和D. petrodavisianum在形态上非常相似。然而,在我们的研究中,已经确定两个物种在形态、解剖和孢粉学方面存在一些差异。根据所获得的数据,揭示了两个物种之间的异同。两种植物根的横切面上有表皮、皮层、维管束组织和中央区域,茎的横切面上有表皮、皮层、维管束和髓。萼片和花瓣的横切面上有上下表皮、薄壁细胞和气管细胞。通过果实的横截面,观察到果实中有两颗种子,并确定了两种果实的果壁。在孢粉学研究中,测定了花粉大小、P/E比、柱头大小、内外壁厚度、轴径和柱头间距。结果表明,纤毛草和石花草的花粉粒为三柄形,扁球状。从花粉粒中得到的结果在所研究的物种中彼此相似。用扫描电镜对两种植物的果实和种子进行了观察。测定微形态差异和相似之处。该物种的果实是卵泡和球形的。种子呈黄褐色,近金字塔形,细纹纹饰。植物分类单元。30(1):77- 88,2023 (6)

A morphological, anatomical and palynological investigation on Delphinium cilicicumP.H. Davis & Kit Tanand D. petrodavisianum Ilarslan & Kit Tan
In the present study, the morphological, anatomical and palynological properties of endemic species Delphinium cilicicum P.H. Davis & Kit Tan and D. petrodavisianum İlarslan & Kit Tan belonging tothe genus Delphinium L., Ranunculaceae of Turkey were investigated. D. cilicicum and D. petrodavisianum are very similar morphologically. However, in our studies, it has been determined that there are some differences between the two species in terms of morphological, anatomical and palynological aspects. Based on the data obtained, the similarities and differences between two species were revealed. The cross-sections taken from the roots of two species have peridermis, cortex, vascular tissue and central region, in cross sections taken from the stem have epidermis, cortex, vascular bundle, and pith. In cross sections taken from the sepal and petal have lower and upper epidermis, parenchyma cells and tracheal cells. Through cross-sections of fruit, it was observed that there were two seeds in the fruit and the fruit wall was determined in two species. In palynological research, pollen size, P/E ratio, colpus size, intine-exine thicknesses, amb diameter and distance between colpus were measured. It was revealed that D. cilicicum and D. petrodavisianum had tricolpate, oblate-spheroidal pollen grains.The results obtained from the pollen grains were similar to each other in examined species. The fruits and seeds of two species were examined using SEM microscopy. Micromorphological differences and similarities were determined. The fruits of the species are follicle and globose. The seeds are yellowish brown, sub pyramidal and fine-grained ornamented. Bangladesh J. Plant Taxon. 30(1): 77-88, 2023 (June)

期刊介绍: Bangladesh is a humid, subtropical country favouring luxuriant growth of microorganisms, fungi and plants from algae to angiosperms with rich diversity. She has the largest mangrove forest of the world in addition to diverse hilly and wetland habitats. More than a century back, foreign explorers endeavoured several floral expeditions, but little was done for non-vasculars and pteridophytes. In recent times, Bangladesh National Herbarium has been carrying out taxonomic research in Bangladesh along with few other national institutes (e.g. Department of Botany of public universities and Bangladesh Forest Research Institute).
