The comparative palynomorphological studies on Turkish Muscari genera and close relatives (Asparagaceae-scilloideae)...

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.
