| analysis of serpentinophytes from north-east of portugal for trace metal accumulation--relevance to the management of mine environment. | in north-east of portugal, the serpentinized area is about 8000 ha with a characteristic geology and flora. the serpentine plant community and respective soils were analyzed to examine the trace metal budget in different tissues of the plants exhibiting resistance to trace metals. one hundred and thirty five plant species belonging to 39 families and respective soils have been analyzed for total co, cr, cu, fe, mn, ni, pb and zn. substantial amounts of ni, cr, co and mn were detected in plant ti ... | 2004 | 14675842 |
| antimony distribution and mobility in topsoils and plants (cytisus striatus, cistus ladanifer and dittrichia viscosa) from polluted sb-mining areas in extremadura (spain). | a study about topsoil antimony distribution and mobility from the soils to the biomass has been afforded in three abandoned sb mining areas located at extremadura. physico-chemical characteristics of the soils and total antimony levels were measured in soils and autochthonous plant species (cytisus striatus, cistus ladanifer and dittrichia viscosa). comparison with corresponding values in reference areas isolated from the mining activities is discussed. antimony mobility in the soils was estimat ... | 2007 | 16730108 |
| behaviour of alpha-, beta-, gamma-, and delta-hexachlorocyclohexane in the soil-plant system of a contaminated site. | the behaviour of the organochlorine pesticide hexachlorocyclohexane (hch) is investigated. the concentrations of alpha-, beta-, gamma-, and delta-hch isomers were measured in soils, rhizosphere and vegetation in a contaminated area in galicia (nw spain). the total concentration of hch in soils reached values close to 20,000 mgkg(-1). the plants analysed (avena sativa l., chenopodium spp., solanum nigrum l., cytisus striatus (hill) roth, and vicia sativa l.) accumulated hch, especially the beta-h ... | 2006 | 16824654 |
| phytoremediation of hexachlorocyclohexane (hch)-contaminated soils using cytisus striatus and bacterial inoculants in soils with distinct organic matter content. | the performance of cytisus striatus in association with different microbial inoculant treatments on the dissipation of the insecticide hexachlorocyclohexane (hch) was studied. two soils with different organic matter (a and b soil) content were spiked with 0 or 65 mg hch kg(-1). plants were either not inoculated (ni), or inoculated with the endophyte rhodococcus erythropolis et54b and the hch-degrader sphingomonas sp. d4 separately or in combination (et, d4 and etd4). unplanted pots were also est ... | 2013 | 23583940 |
| no evidence for fabaceae gametophytic self-incompatibility being determined by rosaceae, solanaceae, and plantaginaceae s-rnase lineage genes. | fabaceae species are important in agronomy and livestock nourishment. they have a long breeding history, and most cultivars have lost self-incompatibility (si), a genetic barrier to self-fertilization. nevertheless, to improve legume crop breeding, crosses with wild si relatives of the cultivated varieties are often performed. therefore, it is fundamental to characterize fabaceae si system(s). we address the hypothesis of fabaceae gametophytic (g)si being rnase based, by recruiting the same s-rn ... | 2015 | 26032621 |
| influence of the drying method in the antioxidant potential and chemical composition of four shrubby flowering plants from the tribe genisteae (fabaceae). | flowers from several common mediterranean shrubs, such as those from the cytisus genus and genista genus (tribe genisteae/fabaceae) have long been used for medicinal purposes and seasoning in the northeastern portuguese region. despite, the shade-drying traditionally used to process these plants, freeze-drying is claimed to better preserve the quality of medicinal plants. herein, the effects of drying process in the antioxidants composition and properties of cytisus multiflorus, cytisus scopariu ... | 2011 | 21816201 |
| megasporogenesis, megagametogenesis and ontogeny of the aril in cytisus striatus and c. multiflorus (leguminosae: papilionoideae). | there are few embryological reports on wild legumes and even fewer on their seminal appendages. there are no existing studies on the complete ontogeny of these appendages in cytiseae, a very important papilionoideae tribe in mediterranean ecosystems. in this work megasporogenesis, megagametogenesis and aril ontogeny were studied in cytisus multiflorus and c. striatus, endemics from the western mediterranean region. | 2006 | 16873423 |
| use of plant growth promoting bacterial strains to improve cytisus striatus and lupinus luteus development for potential application in phytoremediation. | plant growth promoting (pgp) bacterial strains possess different mechanisms to improve plant development under common environmental stresses, and are therefore often used as inoculants in soil phytoremediation processes. the aims of the present work were to study the effects of a collection of plant growth promoting bacterial strains on plant development, antioxidant enzyme activities and nutritional status of cytisus striatus and/or lupinus luteus plants a) growing in perlite under non-stress c ... | 2017 | 28069305 |
| patterns of growth costs and nitrogen acquisition in cytisus striatus (hill) rothm. and cytisus balansae (boiss.) ball are mediated by sources of inorganic n. | nitrogen-fixing shrubby legumes in the mediterranean area partly overcome nutrient limitations by making use of soil n and atmospheric n₂ sources. their ability to switch between different sources lets them adjust to the carbon costs pertaining to n acquisition throughout the year. we investigated the utilization of different inorganic n sources by cytisus balansae and cytisus striatus, shrubby legumes under low and a sufficient (5 and 500 µm p, respectively) levels of p. plants grew in sterile ... | 2016 | 27135240 |
| influence of plant root exudates on the mobility of fuel volatile compounds in contaminated soils. | vegetation and its associated microorganisms play an important role in the behaviour of soil contaminants. one of the most important elements is root exudation, since it can affect the mobility, and therefore, the bioavailability of soil contaminants. in this study, we evaluated the influence of root exudates on the mobility of fuel derived compounds in contaminated soils. samples of humic acid, montmorillonite, and an a horizon from an alumi-umbric cambisol were contaminated with volatile conta ... | 2014 | 24933887 |
