Roots of seedlings of the "beefwood" tree, Casuarina cunninghamiana Miq. grown in nitrogenfree nutrient solution were inoculated with a suspension prepared from crushed root nodules taken from mature plants. Marked deformation of root hairs was evident but no infection threads were observed in root hairs. The mode of infection remains undetermined. Root nodules were initiated within three weeks...
this paper presents the results obtained from the life cycle assessment (lca) of the productionof sicilian artichokes (cynara scolymus) with the aim of reducing impacts, interpreting the results, suggesting possible improvements and enriching the sustainability knowledge already existing in the agro food field. artichokes represent one of the excellent italian agricultural products even if stil...
urban sinks accumulate phosphorus and other elements and may serve as sources of secondaryraw materials. this paper evaluates phosphorus sources based on their environmental impact. in a life cycleassessment (lca) the conventional production was used as a yardstick against which tomeasure the performanceof two recycling options: spreading of sewage sludge and phosphorus recovery from municipal ...
magnetic levitation (maglev) is amongst the most advanced technologies that are available to the transportation industries. it has already been noticed by decision makers in many countries around the globe. contrary to such high levels of interest, there are no practical algorithms available to the engineers and/or managers to assist them in analyzing economics of the maglev systems. therefore,...
8 strains of endophytic actinomycetes were successfully isolated from root nodules of Elaeagnus angustifolia by the methord of nodule-slicing respectively on three mediums S, FTW and DPM. And these strains were analyzed by 16S rDNA phylogenetic studies, the result showed that 5 of these strains belonged to Micromonospora, and the other 3 strains was Nonomuraea, Pseudonocardia and Planotetraspor...
life cycle study of a product is an accepted method for determining the side effects of its production process on environment during its complete life cycle. in this research, the impacts of global warming, acidification, terrestrial eutrophication and fossil resources depletion per unit yield of wheat (ton) on environment were investigated using life cycle assessment method in marvdasht region...
UNLABELLED PREMISE OF STUDY A survey of the root-nodule symbiosis in Astragalus and its interaction with selenium (Se) has not been conducted before. Such studies can provide insight into how edaphic conditions modify symbiotic interactions and influence partner coevolution. In this paper plant-organ Se concentration ([Se]) was investigated to assess potential Se exposure to endophytes. • ...
