“…maxima pollen displayed a globular form characterized by distinctive stigma stratification. In the case of Lagenaria siceraria, observations revealed exine with a spherical, symmetrical configuration and a psilate surface(Kouonon et al, 2009) Lutz et al (2021). conducted an investigation into pollen morphotypes across six Cucurbit species to enhance the comprehension of their phylogenetic classification.…”

This study employs scanning electron microscopy (SEM) to delve into the intricate pollen morphology of Cucurbitaceae (Gourd Family) species, unraveling the nuanced details of their structural features. Concurrently, the research investigates the antimicrobial potentials encoded within these pollen grains, shedding light on their possible applications in the realm of natural antimicrobial agents. Cucurbitaceae plants showcases significant antibacterial and antifungal potentials, underscoring its potential as a source for novel antimicrobial compounds. This research endeavors to provide a comprehensive analysis of pollen morphometry in 12 Cucurbitaceous species, with the primary goal of identifying pollen morpho‐types to enrich the taxonomic understanding of the Cucurbitaceae. Following the Erdtman protocol, the study involved processing, measuring, and capturing pollen grains using SEM techniques. Qualitative data were analyzed to evaluate the variations in pollen types, size, and exine stratified sculptured layering. The pollen grains exhibit characteristics of being monads, ranging in size from medium to very large, with the prevailing shape being prolate‐spheroidal in six species. Notably, the maximum polar axis diameter was recorded for Cucurbita pepo (106.3 μm), while the minimum was observed in Zehneria anomala (32.6 μm). The grains of Cucurbitaceae exhibit diverse surface patterns, including reticulate columellae, reticulate, verrucate‐scabrate, verrucate‐gemmate, echinate baculate, reticulate‐perforate, and micro‐reticulate. This SEM investigation illuminates the intricacies of Cucurbitaceae pollen morphology while concurrently highlighting their noteworthy antimicrobial potentials.Highlights High‐resolution imaging reveals complex pollen morphology. Identification of unique antimicrobial structures on Cucurbitaceae pollen (gourd family). Exploring medicinal potential: Antimicrobial properties of cucurbitaceae species.
