Taxonomic study of pollen grains for five species of Fabaceae Family

Abstract

The objective of the study was to provide valuable palynological characteristics for the identification of Fabaceae taxa, which could potentially serve as distinguishing features for closely related species differentiation. Pollen samples were collected from fully developed flowers of 25 samples, encompassing five species within the Fabaceae Family Colutea cilicica Boiss. & Balansa, Glycyrrhiza glabra L., Spartium junceum L., Robinia pseudoacacia L., and Anagyris foetida L. The investigation involved the utilization of both light microscopy and electron scanning microscopy. Consequently, the observed pollen grains exhibited monad symmetry and were of medium to small dimensions. These grains displayed diverse ornamentation patterns including perforations, fossulate, reticulations, regular structures, and granulations. Moreover, a wide array of outline shapes was noted for pollen grains in both equatorial and polar views. Detailed examinations were performed using both light microscopy (LM) and electron scanning microscopy (SEM) techniques, revealing distinct differentiating characteristics among the examined taxa.
