Abstract
: In this study, pollen and seed morphologies of Symphyandriformes section members are investigated by using light microscope (LM) and scanning electron microscope (SEM). All of the three types belonging to this section are euxine elements and they are endemic: C. betulifolia, C. troegerae, C. choruhensis. Sections have been investigated for the first time both with respect to pollen, seed morphology and with respect to ecological features and the data obtained. Basic pollen form is oblate-spheroidal and has three apertures in all of the sect. While exine sculpturing pattern is granulate-scabrate at C. betulifolia and C. choruhensis, it is rugulate-microreticulate at C. troegerea. As per seed surface morphology, for the whole section a single main genus has been defined in the form of striate testa. Seed structure is in the form of long striates which are regular and significant and its has a liny structure. Physical and chemical analysis of soils where section members are raised have been realized. It is observed that all of the 3 plants preferred mild, medium and strong alkali soils with clayey- loam, calcerous structure. As per the chemical analysis of soil, it is determined that they preferred soils that comprised very few organic substances and low level of phosphorus (C. troegerae, C. choruhensis) and medium level as well (C. betulifolia), and soils that comprised low level of potassium (C. troegerae, C. choruhensis), and high levels as in C. betulifolia.
