This study was conducted to explore the major sources of pollutants including total suspended particles and levels of NOx,COx,and SOx in Faisalabad Pakistan,which make key contributions to the smog in *** is the third largest city of Pakistan where the situation is aggravating due to industrial expansion,population growth and an increasing volume of *** was conducted for the period of three months at different stations in *** concentrations of total suspended particles,levels of NOx,SOx and COx are 160μg/m^(3) to 506μg/m^(3),26μg/m^(3) to 64μg/m^(3),110μg/m^(3) to 139μg/m^(3) and 5.5 mg/m^(3) to 18.2 mg/m^(3),*** a result,air pollution control should not simply focus on controlling particulate emission,but also involve adopting an integrated multi-pollutant control *** concentrations were at an intermediate level with respect to parameters by using Geographical Information System(GIS)and *** results were compared with the permissible limits of United States Environmental Protection Agency(USEPA)and National Environmental Quality Standards(NEQS).

Genetic Variation among Seedling of Pumpkins Genotypes through SDS-Page

引用

American Journal of Plant Sciences 2021年第5期12卷 711-719页

Genetic diversity in 30 genotypes of Pumpkins was collected from unexplored mountainous areas of Khyber Pakhtunkhwa, Pakistan was investigated through biochemical characterization. For biochemical characterization, Sodium Dodecyl Sulphate Polyacrylamide Gel Electrophoresis was carried out. The seed proteins were resolved on 7.5% and 15% polyacrylamide gel. A total of 35% genetic disagreement was observed in the collected lines with linkage distances ranging from 0.00 - 0.83 (percent disagreement). Similarly, cluster analysis sorted total germplasm on the basis of 12 bands (total bands) into eight clusters. Present study revealed a considerable amount of genetic diversity explored in pumpkin germplasm, Cluster analysis exhibited moderate level of genetic diversity;to broaden the gene pool. Further collection of the important germplasm is needed to be used in the development of improved cultivars with respect to quality and quantity.

Antimicrobial and Antioxidant Activities of Methanolic Extract and Fractions of <i>Epilobium roseum</i>(Schreb.) against Bacterial Strains

引用

American Journal of Plant Sciences 2021年第3期12卷 275-284页

作者： Muhammad Ikram niaz Ali Gul Jan Farzana Gul Jan Muhammad Romman Muhammad Ishaq yasir Islam Naeem Khan Department of Botany Hazara University Mansehra Pakistan Department of Botany Abdul Wali Khan University Mardan Pakistan Department of Botany University of Chitral Chitral Pakistan Department of Plant Sciences Quaid-i-Azam University Islamabad Pakistan

Present study aims to evaluate antimicrobial and antioxidant activities of the crude methanolic extract and different fractions of the Epilobium roseum (Schreb). The extract and fractions were used against pathogenic bacteria (Bacillus subtilis, Bacillus atrophaeus, Klebsiella pneumonia and Pseudomonas aeruginosa) and fungal strains (Aspergillus niger and Aspergillus flavus). The methanolic extract and their sub fraction n-hexane showed a prominent inhibition zone against all bacterial strains but inactive against fungal strains. The various extracts of Epilobium roseum (Schreb) from various parts were tested for their antioxidant activity by 1,1-Diphenyl-2-picryl-hydrazyl (DPPH) assay. The IC
