Abstract:
Cyperaceae that have sedges are present in several ecotypes in Pakistan as well as in other countries. The focus of the current work is the structural alteration of various Cyperaceae species' roots and stems for increased resistance to abiotic stress. Members of the family Cyperaceae are able to thrive in a wide range of habitats in Pakistan, including arid and semi-arid areas (Cyperus arenarius, C. rotundus), waterlogged saline areas (Schoenoplectus spp.), industrially polluted habitats (C. alopecuroides) aquatic wetlands (Scripus spp., Kyllinga spp., Fimbristylis spp. and Cyperus spp.) and cooler sub-mountainous salt range areas (Carex spp.). The species of Cyperus alternifolia is the most frequently grown in Pakistan. Every species under investigation had some distinct structural adaptations to tolerate environmental risks. Drought-resistant species (C. conglomeratus) had extensive sclerification in both the vascular regions and cortical. The cortical parenchyma of this species is packed closely together. These adjustments are vital for both water saving and reducing water loss through roots. Halophytic/salt-tolerant species (Schoenoplectus spp.) have dense aerenchyma and well-developed sclerenchyma in the cortical area. Stellate cells have also been seen in these species. They aid in salt transfer, dilution, and water conservation. The unique aerenchyma seen in the roots of aquatic organisms is essential for gaseous exchange in anaerobic environments.
