Palynological Palynological Investigation of Allergenic and Invasive Weeds Plants for Biodiversity in District Lakki Marwat Using Scanning Electron Microscopy

Abstract

A total of 16 different allergenic and invasive weed species belonging to 12 different families collected from different areas of study area. Among the studied plants, most of the species belong to the Asteraceae family. For morphological studies of pollen through LM and SEM the samples were acetalized. We done the fieldwork for the collection of weed plants and also performed the experimental work i.e. SEM and LM for the pollen morphology. Most of the species recorded with pollen of tricolporate and echinate. Species belonging to Asteraceae were considered as most abundant and allergenic as compared to others. The maximum polar diameter was noted in the Convolvulus arvensis is 40.00 µm and the minimum were noted in Oxalis corniculata is 6.15 µm. Maximum exine thickness was noted in convolvulus arvensis is 3.70 µm and Minimum were noted in Sorghum halepense is 1.65 µm. It was noticed that most of the allergenic and invasive weeds found in plain areas of Lakki Marwat during September and April. Present study provides information about the allergenic and invasive weeds plants and their threats to biodiversity. The pollen of such weed plants causes asthma and atopy disease in humans.

Palyno‐morphological attributes of some selected plant species of family Asteraceae from district Dera Ismail Khan, KPK, Pakistan

“…The large‐sized grain with maximum PD was E. echinatus (87.5 μm) and the small‐sized grain with minimum PD was A. subulatus (21 μm). Our findings are dissimilar to the study carried by Khan et al (2020) and Perveen (1999) (Figure 4).…”

Palyno‐morphological diversity of Asteraceous and Poaceous allergenic plant using microscopic techniques in lesser Himalaya‐Pakistan

“…Exine ornamentation show pollen were micro‐echinate, granulate, and lacunae were present. Our findings are similar to Diez et al (1999), Perveen (1999), Ghahraman et al (2007), Ahmad et al (2013), Shaheen et al (2018), Hussain et al (2019), Alam et al (2020) Khan et al (2020), and Ali et al (2021).…”

“…After visualizing pollen presence under light microscope Slide were made permanent with the help transparent nail paint. Tagging tape were used for giving slide number or name according to choose (Khan et al, 2020).…”

“…After visualizing pollen presence under light microscope Slide were made permanent with the help transparent nail paint. Tagging tape were used for giving slide number or name according to choose(Khan et al, 2020).Pollen slides were studied under the light microscope (MEIJI TECHNO) (Model: MT4300H). Pollen samples were examined under 100Â, 400Â magnification.…”

Microscopic techniques for fabrication of polyethersulfone thin‐film nanocomposite membranes intercalated with UiO‐66‐SO3H for heavy metal ions removal from water

“…Water is used as a modulator to enhance the rate of nucleation resulted in the formation of homogeneous crystals and reduces amorphous end product precipitation (He et al, 2017). Just like this research, microscopic techniques using SEM help in studying outer layer of exine and epidermal surfaces in plants (F. Khan et al, 2020; Gul et al, 2019; M. Ahmad, Ozdimir, Zafar, Ahmad, & Sultana, 2019; Mir et al, 2019; Nazish et al, 2020; Noor, Ahmad, Zafar, & Ashraf, 2017; Rahman, Ahmad, Zafar, Mumtaz, & Shah, 2017; Raza et al, 2020; S.
