And there is a great risk for those who do so of being then drowned in the mass of data collected. Fortunately, there are effective methods of conducting a survey count and not being satisfied with the superficial results provided by simply examining the distribution of responses. This book presents in an educational way several advanced methods of statistical analysis of survey data, in particular the factorial analysis of correspondences and logistic regression, which, by using software which is now increasingly easy to use, allow '' exploit the data in depth.Bibliothèque idéale des sciences sociales.MathematicsHILCCPhysical Sciences & MathematicsHILCCMathematical StatisticsHILCCméthodeanalyse des correspondancesstatistiqueMathematicsPhysical Sciences & MathematicsMathematical StatisticsCibois Philippe118790Pierre MerckléPQKBUkMaJRUBOOK9910133530503321Les méthodes d'analyse d'enquêtes2015811UNINA03068nam 2200445z- 450 991026113240332120210212(CKB)4100000002484762(oapen)https://directory.doabooks.org/handle/20.500.12854/58605(oapen)doab58605(EXLCZ)99410000000248476220202102d2017 |y 0engurmn|---annantxtrdacontentcrdamediacrrdacarrierRole of Silicon in PlantsFrontiers Media SA20171 online resource (186 p.)Frontiers Research Topics2-88945-352-9 Silicon (Si) is gaining increased attention in the farming sector because of its beneficial effects observed in several crop species, particularly under stress conditions. The magnitude of benefits is predominantly observed in plant species that can accumulate Si above a certain threshold. Therefore, deciphering the molecular mechanisms and genetic factors conferring a plant ability to take up silicon is necessary. Along these lines, several efforts have been made to identify the specific genes regulating Si uptake and distribution in plant tissues. This information finds its usefulness in identifying Si-competent species, and could eventually lead to improving this ability in low-accumulating species. The successful exploitation of Si in agriculture depends highly on the understanding of different Si properties including plant-available Si from the soil, transport within tissues, deposition in planta, and Si effect on different metabolic and physiological processes. In addition, a better comprehension of external factors influencing Si uptake and deposition in plant tissue remains important. A plant can take up Si efficiently only in the form of silicic acid and most soils, despite containing high concentrations of Si, are deficient in plant-available Si. Consequently, soil amendment with fertilizers rich in plant-available Si is now viewed as an affordable option to protect plants from the biotic and abiotic stresses and achieve more sustainable cropping management worldwide. Articles compiled in the present research topic touch upon several aspects of Si properties and functionality in plants. The information will be helpful to further our understanding of the role of Si and contribute to exploit the benefits plants derive from it.Botany & plant sciencesbicsscbiotic and abiotic stressOmics approachesplant resilienceprotein structuresilicon fertilizationsilicon uptake mechanismtranscriptometransporter proteinsBotany & plant sciencesRichard R.
