To examine anatomical adaptations in a potential forage grass, Imperata cylindrica (L.) Raeuschel, a population was collected from the natural salt-affected soils of the Salt Range, Pakistan. Using a hydroponic system, the degree of salt tolerance in terms of structural modifications in the Salt Range ecotype was compared with that in an ecotype collected(More)
Populations of three salt tolerant forage grasses (Cynodon dactylon, Imperata cylindrica, and Sporobolus arabicus) were collected from the salt-affected soils of the Salt Range and normal non-saline soils of the Faisalabad region to assess their mechanism of adaptation to saline stress by determining ion relations and some specific anatomical modifications.(More)
Desert plants show specific mechanisms to thrive under prevailing harsh conditions. To study the survival mechanism(s) in native desert plant species, Lesser Cholistan desert in Pakistan was surveyed and two potential salt secretory grass species, Aeluropus lagopoides and Ochthochloa compressa, were selected from five saline sites. Both these grasses(More)
Five distinct habitats in the Cholistan desert were explored for phytoecological attributes and species association. Community structure and distributional pattern of the species was mainly dependent on the salinity gradient. Relatively more salt tolerant species viz., Sporobolus ioclados with Aeluropus lagopoides, Haloxylon recurvum and Suaeda fruticosa(More)
Some ecologically different ecotypes of Panicum antidotale Retz. were evaluated for drought tolerance in relation to growth parameters and leaf structural modifications. These ecotypes were adapted to normal non-stressed (agricultural field AF, and sludge of disposal channel SDC), drought-stressed (along roadside AR), salinity-stressed (forest plantation(More)
Two populations of cogongrass [Imperata cylindrica (L.) Raeuschel], one from the saline regions of the Salt Range and the other from the non-saline regions of Faisalabad were assessed for salinity tolerance on the basis of some key morphological and physiological attributes. It was hypothesized that the tolerant population from the Salt Range must have(More)
Five differently adapted natural populations of the native salt desert grass Lasiurus scindicus Henrard from Lesser Cholistan Desert (Pakistan) in South Punjab of east central Pakistan, were evaluated to examine their mechanism of adaptation to saline stress based on some key morpho–anatomical and physiological characteristics. Five ecotypes were collected(More)
Received: Revised: Accepted: Online available: January 08, 2015 November 20, 2015 February 07, 2016 March 11, 2016 The present study was conducted to determine the antiviral activity of different Cholistani plants growing in the Cholistan Desert, Pakistan. Methanolic extracts of plants were prepared by dissolving air-dried, powdered plants in methanol and(More)
Three differently adapted populations of sewan grass (Lasiurus scindicus Henr.) were evaluated for structural and functional adaptations to high salinity. The habitats were Derawar Fort (DF, least saline, ECe 15.21), Bailahwala Dahar (BD, moderately saline, ECe 27.56 dS m−1) and Ladam Sir (LS, highly saline, ECe 39.18 dS m−1) from within the Cholistan(More)
