Abstract
The present work is aimed to study the pollen morphology of weed plants by light microscopy (LM). Polleniferous material of eight weed plants viz., Mimosa pudica, Cleome viscosa, Tribulus terrestris, Lantana camara, Commelina benghalensis, Ziziphus mauritiana, Cardiospermum halicacabum and Datura stramonium were collected from in and around agricultural lands of Nizamabad district, Telangana, India during 2022-2023.The pollen features viz., shape, apertures and the sporoderm pattern was studied. The pollen grains studied showed spheroidal, sub- prolate, eu-oblate, oblate-spheroidal, oblate to per oblate shape. The apertural diversity include tricolporate, triporate, pantoporate and monosulcate condition. The Exine ornamentation is indicated by psilate in three species, striate in two, reticulate in another two species and one species possess microechinate pattern. The diversity in pollen features are helpful in the identification of the taxa at various levels. This study highlights the some of the common weed pollen morphological features useful to distinguish the species of weeds.
