| Özet |
| In this study, palynological, seed andleaflet micromorphological properties ofAstragalus victoriaeandAstragalusmelanophruriusspecies were investigated in detail using lightmicroscopy (LM) and scanning electron microscopy (SEM). The aim of this studyis to determine the contribution of pollen, leaflet and seed morphologycharacters in distinguishing between these two closely related species. Studyresults indicate that pollen of species are radial symmetricand isopolar. Aperture type is trizonocolporate. Pollenshape is determined as prolate-spheroidalfor Astragalus melanophrurius and subprolate for Astragalus victoriae. Ornamentationtype is observed as perforate at polar area and aperture surround, microreticulate at the other sides ofpollen for A. melanophrurius while ornamentation determined asrugulate at polar area and aperture surround, microreticulate at the other sides ofpollen for Astragalus victoriae. Seeds shape arereniform, the colour is light brown and surface ornamentation determined aspsilate in light microscope for both species while reticulate-rugulate with thin and irregularmuri determined in Astragalus victoriae and reticulate surface ornamentation with thickand regular muri in Astragalus melanophrurius in SEM micrograph. Leaflet observed as elliptic-ovate, emarginatedwith dens single celled trichomes on lower surface for A. melanophrurius while narrowly elliptic, apiculate,with densely single-celled trichomes on lower surface leaflet observed for A.victoriae. Trichomes havescabrate ornamentation at A. melanophrurius and striate ornamentation at A. victoriae. On the lower surface of the leafletof A. victoriae 240 stomas and … |
