(malvaceae), leaves of potentilla reptans l. (rosaceae), fruits of rumex patientia l. (polygonaceae), aerial parts of sanguisorba mi ... | 2005 | 16085377 |
| ethnopharmacological survey of wild medicinal plants in showbak, jordan. | two main research questions are framing this investigation: (1) the main taxa of the medicinal importance value altered the showbak forest stand and species composition? (2) the most safe species and what are the toxic ones (unsafe). these two research questions are the vital ones to draw a clear image about the wild medicinal plants of this investigated area of showbak region in jordan. 79 wild medicinal plant species were investigated in this study which are used in traditional medication for ... | 2009 | 19429338 |
| an ethnobotanical survey of medicinal plants in sivrice (elazığ-turkey). | this study aimed to identify wild plants collected for medical purposes by the local people of sivrice county, located in the eastern anatolia region of turkey, and to establish the uses and local names of these plants. | 2010 | 20713142 |
| evaluation of native plant flower characteristics for conservation biological control of prays oleae. | several studies have shown that manipulating flowering weeds within an agroecosystem can have an important role in pest control by natural enemies, by providing them nectar and pollen, which are significant sources of nutrition for adults. the aim of this study was to assess if the olive moth, prays oleae (bernard, 1788) (lepidoptera: praydidae), and five of its main natural enemies, the parasitoid species chelonus elaeaphilus silvestri (hymenoptera: braconidae), apanteles xanthostigma (haliday) ... | 2016 | 26780918 |
| operation of the xanthophyll cycle in higher plants in response to diurnal changes in incident sunlight. | changes in the carotenoid composition of leaves in response to diurnal changes in sunlight were determined in the crop species helianthus annuus l. (sunflower), cucurbita pepo l. (pumpkin), and cucumls sativus l. (cucumber), in the diaheliotropic mesophyte malva neglecta wallr., and in the perennial shrub euonymus kiautschovicus loesner. large daily changes were observed in the relative proportions of the components of the xanthophyll cycle, violaxanthin (v), antheraxanthin (a), and zeaxanthin ( ... | 1992 | 24186736 |
| ethnobotany of medicinal plants in district mastung of balochistan province-pakistan. | the aim of this study was to document the medicinal uses of plants in district mastung of balochistan province, pakistan. the ethnobotanical results contain quantitative information on medicinal plants diversity documented for the first time in the area. | 2014 | 25260579 |
| phytodermatitis in eastern turkey: a retrospective, observational study. | plant life is extremely diverse, with a great deal of geographic and seasonal variation. consequently, the range of reported adverse reactions is large, and there are important differences worldwide in the incidence and prevalence of these reactions. systemic ingestion of some plants containing furocoumarins can cause erythema, edema, vesicle and bulla formation and later hyperpigmentation, after exposure to sunlight. they may at times exhibit clinical manifestations that mimic angioedema, and r ... | 2015 | 24776729 |
| air pollution tolerance index of plants around brick kilns in rawalpindi, pakistan. | in any contaminated environment, the sensitive plant species can serve as bio-indicator of air pollution while tolerant plant species can act as a sink for air pollutants. air pollution tolerance index (apti) is an important tool to screen out plants based on their tolerance or sensitivity level to different air pollutants. the present study was aimed to identify the sensitive and tolerant plant species in the vicinity of brick kilns in the rawalpindi city. to determine the susceptibility level ... | 2017 | 28061409 |
| relationships between some soil parameters and weed community (case study: winter wheat fields of uremia-iran). | in order to find relationships between weed species distribution and soil ph, calcium carbonate (caco₃), electrical conductivity (ec), and organic matter percentage (om %), fields surveys were done in 50 wheats (triticum aestivum l.) fields of uremia county (one of the northwest counties of iran) in 2013. data sampling of weeds was conducted from the beginning of stem elongation until the end of heading stages of wheat. in each field, 20 quadrates (0.25 m²) were randomly placed along a "w" patte ... | 2015 | 27145592 |
