By this study, the palynomorphological traits of 49 taxa (53 plant samples) of the genus Muscari which has been the main research topic and also its relatives, Pseudomuscari, Hyacinthella and Bellevalia have been studied in details of both using light and scanning electron microscope. In the end of palynologic works, it was suggested the descriptive or symbolized main pollen types to make easier the separation or identification of the species of Muscari and its relative groups. According to this symbolization, the pollen types of species may be changeable as D-shaped, elliptical, triangular, and spindle shaped and all types could be seen in different members of the studied taxonomic groups in this paper. One of the most important findings of the study is that the taxa of the genus Muscari, Hyacinthella and Bellevalia do not show a main difference in terms of pollen structures and especially they exhibit harmony. Therefore, it does not possible to mention about the special pollen shape own to one species but it is possible to see common pollen types for closely related taxa or taxon groups. As a result, it could be commented that there is not evolved the close taxonomical groups within Asparagaceae in terms of pollen shape and morphologies and there is considerably a high suitability in point of theirs germ cells or microspores among them. RESEARCH HIGHLIGHTS: A detailed palynological description is provided for Muscari and close relative genus using scanning electron microscopy (SEM) and light microscopy (LM). Pollen size and sulcus length are been determined as the best informative pollen characters to understand Muscari and other studied species.
通过这项研究,详细研究了属 Muscari 的 49 个分类群(53 个植物样本)的花粉形态特征,Muscari 是主要研究对象,其相关属 Pseudomuscari、Hyacinthella 和 Bellevalia 也通过光镜和扫描电子显微镜进行了详细研究。在孢粉学工作结束时,建议使用描述性或象征性的主要花粉类型,以便更容易分离或鉴定 Muscari 及其相关群的物种。根据这种符号化,物种的花粉类型可能会发生变化,例如 D 形、椭圆形、三角形和纺锤形,并且在本文研究的分类群的不同成员中都可以看到所有类型。该研究的最重要发现之一是,Muscari、Hyacinthella 和 Bellevalia 属的分类群在花粉结构方面没有表现出主要差异,特别是它们表现出和谐。因此,不可能提到一个物种特有的花粉形状,但可以看到密切相关的分类群或分类群具有共同的花粉类型。因此,可以评论说,在花粉形状和形态方面,天门冬科内没有进化出密切相关的分类群,并且它们的生殖细胞或小孢子之间存在相当高的适宜性。研究亮点:使用扫描电子显微镜 (SEM) 和光镜 (LM) 对 Muscari 和密切相关的属进行了详细的孢粉学描述。花粉大小和槽长度被确定为理解 Muscari 和其他研究物种的最佳信息花粉特征。
