“…In this instance, the invasive species Bidens pilosa was weakened in the Lomié subdivision during the COVID-19 pandemic as a result of local inhabitants’ repeated and unchecked usage of it. In actuality, taking cuttings from stems and roots causes plants to die because it eliminates the cambium, which is necessary for stem and root secondary growth [ 25 , [37] , [38] , [39] ].…”

“…Pollen grain micromorphology shows that they contain various chemicals such as exines (Abbas et al, 2022). These chemicals can be used in different ways such as delivering medicine, creating new materials, acting as templates, making carbon microspheres and helping in protein chromatography (Ares et al, 2022; Lu et al, 2014; Majeed et al, 2022). High‐performance thin‐layer liquid chromatography (HPTLC) is a chromatographic technique that has several advantages when compared with other techniques (Ristivojević et al, 2020).…”

This study describes a robust chromatographic authentication methodology for herbaceous pollen, employing gas chromatography–mass spectrometry (GC–MS), high‐performance liquid chromatography (HPLC) and high‐performance thin liquid chromatography (HPTLC) protocols. The comprehensive profiling of organic compounds not only distinguishes between different botanical sources but also establishes a reliable framework for quality control and assessment of herbaceous pollen authenticity. Traces of quercetin were detectable using HPTLC in Chaenomeles japonica, and the composition of the mobile phase led to distinct phenolic acid tracks in the extracts of free phenolic compounds. In Lonicera nummulariifolia, prominent chlorogenic acid signal and traces of 3,4‐dihydroxybenzoic acid were identified, along with the presence of vanillic, trans‐ferulic, p‐coumaric and p‐hydroxybenzoic and sinapic as phenolic acid standards. The HPLC chromatogram identified six peaks representing bioactive phenolic compounds such as gallic acid measuring 5.89 ± 0.56 mg g−1, hydroxybenzoic acid 2.39 ± 0.78 mg g−1 and caffeic acid 2.83 ± 0.11 mg g−1. The combined use of GC–MS, HPTLC and HPLC techniques provides a powerful and reliable means of authenticating the botanical origin of herbaceous pollen, offering valuable insights for quality control and ensuring the accuracy of botanical source identification.

“…Palynomorphological examination offers a way to play a role in the systematic classification and identification of plant species at the microscopy level. Amaranthaceous taxa were identified by comparing the microscopic characteristics of various specimens in order to detect differences among them [15]. Advanced microscopy techniques like scanning electron microscopy (SEM) are applied to analyze the morphological traits of plants and their organs.…”

The aim of the study was to visualize the micromorphology of Amaranthaceous pollen using scanning electron microscopy collected from the Thal Desert. Field collection was conducted from July to September 2021. A total of 14 taxa of the family Amaranthaceae were collected which belong to nine genera. Achyranthes aspera, Aerva javanica, Aerva lanata, Amaranthus graecizans, Amaranthus retroflexus, Amaranthus viridis, Bassia indica, Chenopodium album, Chenopodium ficifolium, Chenopodium murale, Digera muricata, Haloxylon stocksii, Salsola tragus, and Suaeda fruticosa were studied in terms of pollen morphotypes. Pollen were acetolyzed and observed under optical and scanning microscopy. Qualitative and quantitative characters were measured to analyze the pollen to uncover its taxonomic significance. Qualitative characters observed were the shape of pollen in polar and equatorial views; the most frequent shape observed was spheroidal in the polar view, whereas in the equatorial view, prolate spheroidal was the dominant shape. Exine ornamentation is the key characteristic of pollen which is very helpful, and eight different types of ornamentations were observed in collected taxa: smooth sparsely granulate, scabrate-spinulose, microspinulose perforate, microechinate scabrate to metareticulate, granulate, nanospinulate, granulate-spinulose perforate, granulate-perforate echinate, and microechinate perforate. Periporate-type aperture was observed among all taxa. Mesoporia, ektexinous bodies, and tectum features also show variations among Amaranthaceous grains. In quantitative character, A. retroflexus recorded highest in polar view 26.3 μm and the lowest was of C. album 12.2 μm. Highest P/E index ratio was recorded in S. fruticosa (1.12) whereas the lowest for D. muricta (0.94). Exine thickness was highest in S. tragus 2.15 μm and lowest in A. graecizans 0.78 μm. The maximum number of pores was recorded as 32-36 in D. muricata. Artificial taxonomic keys were constructed based on findings that reinforce the importance of the micromorphological ultrastructural diversity of pollen among Amaranthaceous taxa. It was concluded that the descriptions of pollen morphotypes presented greatly contribute to our understanding of desert species identification.
