Abstract:

For the first time, micromorphological features of seeds of 6 species of clovers (Trifolium L.) of the Talysh flora, collected from the Lankaran-Lerik region of the Azerbaijan Republic, belonging to 2 subgroups and 4 sections were studied on an electron microscope (SEM). The shape of the seeds, their size, color, surface structure, the shape of hilum and their sizes are important taxonomic fea-tures. The structure of seeds of the studied species refers to 4 types: seeds with granular surfaces; seeds with tuberculate surfaces; seeds, which have a surface with crystal-like ledges. Features of the structure of the spores can be used, when specifying the status of subgenera; and sections, the re-maining morphological features - when determining species of the genus of clover.
