Objective:To document the medicinal and other folk uses of native plants of the area with a view to preserve the ethnobotanical knowledge associated with this area.Methods:The fieldwork was conducted during a period of one year.Data were collected through a semi-structured questionnaire and interviews with indigenous tribal people and traditional health practitioners residing in the study area.Results:The present study documented ethnobotanical uses of 104 plant species belonged to93 genera and 51 families.Results revealed that most of the documented species were used medicinally(78 spp..44.07%).Leaves were found to be the most frequently used part(69 spp..42.86%) for the preparation of indigenous recipes and for fodder.Conclusions:The current research contributes significantly to the ethnobotanical knowledge.and depicts a strong human-plant interaction.There is an urgent need to further document indigenous uses of plants for future domestication.

Role of secondary metabolites of wild marigold in suppression of Johnson grass and Sun spurge

引用

Asian Pacific Journal of Tropical Biomedicine 2015年第9期5卷 708-712页

作者： Sehrish Sadia rahmatullah qureshi Shahida Khalid Brian Gagosh Nayyar Jin-tun Zhang College of Life Sciences Beijing Normal University Department of Botany PMAS University of Arid Agriculture Institute of Plant and Environment Protection National Agricultural Research Center

Objective: To analyze the wild marigold [(Tagetes minuta L.)(T. minuta)] leaf extract with respect to phytochemicals and allelopathic activity. Methods: The aqueous extracts of T. minuta leaves at concentrations of 50%, 75% and 100% were prepared. Preliminary phytochemical analysis was carried out and then allelopathic ef ect of T. minuta on root length, shoot length, germination, fresh and dry weight of Johnson grass and Sun spurge was tested on i lter paper and in soil.Results: Qualitative phytochemical analysis showed the presence of alkaloids, tannins, saponins, l avonoides and terpenoids. The higher concentrations proved to be signii cantly ef ective in reducing almost all the parameters of Sun spurge and Johnson grass in i lter paper bioassay. Supplemented with the soil, all concentrations of leaf extract showed reduction in germination, root and shoot growth, fresh and dry weight of Sun spurge; however, 100% concentration signii cantly reduced the germination of Johnson grass. Conclusions: This study suggests that marigold allelochemicals can be used as an integrated weed management for the production of better crop yield.

The Assessment of Carbon Stocks in the Oak Scrub Forest of Sheringal Valley Dir Kohistan

Open Journal of Forestry 2015年第5期5卷 510-517页

作者： Alamgir Khan Adnan Ahmad Ziaur Rahman Siraj-ud-Din rahmatullah qureshi Juma Muhammad Department of Forestry Shaheed Benazir Bhutto University Sheringal Dir Upper Pakistan Department of Botany University of Peshawar Peshawar Pakistan Department of Botany PMAS-Arid Agriculture University Rawalpindi Rawalpindi Pakistan Department of Environmental Sciences Shaheed Benazir Bhutto University Sheringal Dir Upper Pakistan

The present study estimates carbon stocks (C-stocks) of the Oak scrub forest of Sheringal valley through field inventory. Stem density (haǃ), tree height (m), basal area (m2·haǃ), stem volume (m2·haǃ), stem biomass (t·haǃ), total biomass (t·haǃ), and total C-stock (t·haǃ), were calculated. Stem density varied between 80±8.16 to 510 ± 42 trees haǃ, with a mean value of 226 ± 7 tress haǃ. The average tree height, basal area and stem volume were 5.47 ± 0.76 m, 12.82 ± 0.25 m2·haǃ and 46.37 ± 0.85 m3·haǃ respectively. The total calculated stem biomass was 32.46 ± 0.60 t·haǃ and total tree biomass was 51.61 ± 0.60 t·haǃ. The calculated C-stocks in the Oak scrub forest ranged from 2.005 ± 1.32 t·haǃ to 63.1 ± 3.34 t·haǃ and the mean C stocks was 25.80 ± 0.47 t·haǃ. The results of the study confirmed that the Oak scrub forest acts as a valuable sink of carbon, but this valuable storage factory of carbon faced the problems of excess uses for fuel wood, forage, domestic uses (mostly for construction) and unscientific management. Proper scientific management and proper utilization of the forest can be significant measures to enhance the potential of the forest to stored and sink more carbon and can be included for CDM and REED++ under Keyto protocol.
