Palyno‐morphological investigations of halophytic taxa of Amaranthaceae through SEM from Salt range of Northern Punjab, Pakistan

Abstract

The pollen morphology of 11 salt tolerant plant species of family Amaranthaceae from the salt range of Northern Punjab, Pakistan has been studied. The palyno‐morphological characters were examined using light and scanning electron microscope. The examined all salt tolerant species have a slight difference in size but have similarity in shape, pore ornamentation, and polarity. The observed morphological characters of pollen grains were pollen symmetry, size, shape, pore ornamentation, pore size, number of pores, exine thickness, polar and equatorial diameter and, P/E ratio. Apolar type of pollens has been observed in all species. Shape of pollens was spheroidal. Exine sculpturing of pollen grains was scabrate (six spp), microechinate (four spp), and microechinate‐scabrate (one spp). Different pori numbers were observed in different species. The pantoporate aperturate and sunken pore ornamentation have been reported in all species. A pollen taxonomic key was developed using examined morphological characters for the accurate identification of halophytic taxa. The high fertility and low sterility of pollens confirmed that the selected halophytes are well‐established in the salt region. The findings highlight the taxonomic significance of pollen morphology in correct identification and differentiation of salt tolerant plant species.

Palyno‐morphological characterization of selected allergenic taxa of family Poaceae from Islamabad‐Pakistan using microscopic techniques

“…Pollen grains are measured, analyzed, and micrographed under a LM at various resolutions of Leica Dialux 20. Based on five grain readings, some morphological features were measured using this method (Nazish et al, 2019).…”

“…Further taxonomic study of the is recommended for the correct identification. Micromorphology of plants material have been proven significant in correct identification and discrimination of the species Ashfaq et al, 2018;Ashfaq et al, 2019b;Bahadur et al, 2018b;Bahadur et al, 2019;Gul et al, 2019a;Gul et al, 2019b;Gul et al, 2019c;Naz et al, 2019;Sufyan et al, 2018;Bano et al, 2019;Nazish et al, 2019;Qureshi et al, 2019;Arshad et al, 2019;Rashid et al, 2018). Therefore, they can be utilized in the treatment of infectious diseases caused by resistant microbes.…”

Halophyte Diversity in Pakistan

“…A palynological exploration is a useful application in the phylogenetic and taxonomic identification of many plant families (Khan et al 2018). Nazish et al (2019) investigated pollen morphological characteristics of 11 salt-tolerant plants of Amaranthaceae using scanning electron microscopy from Northern Punjab salt range, Pakistan, and reported apolar-type pollens with spheroidal shape, pantoporate apertures, and sunken pore ornamentation as a characteristic feature of the halophytes of Amaranthaceae. Grigore and Toma (2008) observed morpho-anatomically four halophytes of Chenopodiaceae and reported some adaptive features such as salt hairs, tracheids, and successive cambia.…”
