The importance of palynology in the taxonomy of genus Silene, based on pollen morphology
In this study, the palynology of 33 species of Silene belonging to 15 sections was investigated to examine the correspondence between palynology, morphological sections and phylogenetic trees. The pollen grains were prepared using the acetolysis method. Quantitative and qualitative micromorphological features of pollens were investigated using light microscopy and scanning electron microscopy....
متن کاملA taxonomic study on the genus Silene (Caryophyllaceae) in Iran
The genus Silene includes 98 species in Iran, with 35 endemic to the Iranian plateau (26 species for Iran). The Iranian species are placed in 21 sections. In this article, the most important characteristics for the separation of the sections, relationships between the sections, and an identification key for the sections in Iran are presented. For each section a distribution map is provided. The...

متن کاملin Silene latifolia (Caryophyllaceae)
• Sex ratio polymorphism has been extensively studied in Silene latifolia, but it is neither known whether inbreeding (which is likely to occur under field conditions) affects it nor which of the proposed mechanisms (Y degeneration, X-linked drive) is more important. Both mechanisms predict reduced pollen performance. • In this study, females were crossed with pollen from related and unrelated ...
متن کاملpollen morphology of the genus malus (rosaceae)
pollen morphology of some species of the genus malus (rosaceae) was investigatedtaxonomically. all species are characteristic by tricolpate pollens. exine sculpturing is variable but is mostlystriate. however, species may differ in degree of density of ridges and their orientation. the exine patterns inm. trilobata and m. florentina are very similar and were characterized by short and very bran...
