To elucidate the morphological diversity and genetic characteristics of pollen Polygonatum species, this study utilized a total 46 samples encompassing six species one variety Polygonatum. Scanning electron microscopy (SEM) was employed to examine traits analyze evolutionary patterns relationships among species. The results indicate that grains germplasm are uniformly characterized as monads, heteropolar, bilaterally symmetrical, atreme, possess mono-sulcus. They were peroblate (P/E-ratio = 0.36–0.42) in shape medium large (P 18.17–27.15 μm, E 44.11–67.07 μm) size. And there four types exine ornamentation: reticulate, reticulate–perforate, reticulate–rugulate, reticulate–verrucate. resources classified into clusters based on morphology clustering analysis: P. cyrtonema macropodum grouped cluster I, filipes odoratum II, kingianum var. grandifolium III, alternicirrhosum IV, standing alone. This tentatively suggests morphology, particularly size ornamentation, can serve valuable reference for classification, relationship, genus

Abstract Pollen grains of plant species have unique morphological characteristics. The variability in shape, size, and microscopic pollen surface features can be efficiently used to determine the which they belong. This approach instrumental regions with rich biodiversity species, specifically medicinal plant. creation a dataset for these using SEM images computer vision application beneficial their identification. We developed robust utilizing scanning electron microscopy (SEM) generate high-resolution from 28 importance employed techniques accurate segmentation classification based on diverse features. In this study, comprising 269 5842 was across classes. addition, we created globally accessible database named IMPORTANT (Indian Medicinal Plants Images Dataset Research, Training, Analysis Neural Networks) facilitate easy retrieval sharing images. study effectively identify by through database. Since even closely related vary characteristics, accuracy precision.
