Contribuições agronômicas ao cultivo da vinagreira roxa (Hibiscus acetosella Welw. Ex Hiern) /

Matsinhe, Marisa Aida Diogo, 1983. January 2017 (has links)
Orientador: Filipe Pereira Giardini Bonfim / Banca: Maria Isabel Ferreira / Banca: Gabriela Granghelli Gonçalves / Resumo: A espécie Hibiscus acetocella Welw. Ex Hiern popularmente conhecida por vinagreira roxa é um arbusto de caule semi-lenhoso pertencente à família das malváceas. Usada tradicionalmente como alimentícia e medicinal sendo as partes usadas, folhas, flores e seus cálices jovens, possui propriedades antioxidantes, antifúngicas, antibacterianas e entre outras. Existem poucos estudos realizados ou quase nenhum disponível sobre estudos agronômicos nesta espécie. Assim, o presente trabalho tem como objetivo avaliar o comportamento fitotécnico da vinagreira roxa no que se refere à fenologia, desenvolvimento vegetativo e melhor época de colheita de frutos, adubação orgânica, bem o teor de compostos fenólicos totais e atividade antioxidante. O estudo foi conduzido no Departamento de Horticultura, da Faculdade de Ciências Agronômicas, Universidade Estadual Paulista Júlio De Mesquita Filho, localizada no município de Botucatu, estado de São Paulo. Em casa de sombra foram conduzidos dois experimentos, sendo dois nos períodos de janeiro a Julho (adubação e época de colheita). O experimento de análise fitoquímica foi realizado no laboratório de plantas medicinais e em campo foi conduzido o experimento de fenologia com recurso a 36 indivíduos dos quais usouse 30 . Foi verificada uma alta sincronia da planta em relação as fenofases e pouca correlação com os fatores climáticos. A época com maior número de frutos não coincidiu com frutos de maior peso. O estudo de adubação demostrou que a vinagreir... (Resumo completo, clicar acesso eletrônico abaixo) / Abstract: The Hibiscus acetocella Welw. Ex Hiern species popularly known as purple vinegar is a semi-woody shrub belonging to the malvaceous family. Traditionally used as food and medicine being the used parts, leaves, flowers and their young calyces, it has antioxidant, antifungal, antibacterial and other properties. There are few or almost none studies available on agronomic studies in this species. The objective of this work was to evaluate the phytotechnical behavior of the purple vinegar with regard to phenology, vegetative development and better fruit harvesting season, organic fertilization, as well as total phenolic compounds content and antioxidant activity. The study was conducted at the Department of Horticulture, Faculty of Agronomic Sciences, State University Paulista Júlio De Mesquita Filho, located in the city of Botucatu, state of São Paulo. In the shade house, two experiments were conducted, two in the periods from January to July (fertilization and harvesting season). The experiment of phytochemical analysis was carried out in the laboratory of medicinal plants and in the field was conducted the experiment of phenology with recourse to 36 individuals of whom 30 were used. It was verified a high synchrony of the plant in relation to the phenophases and little correlation with the climatic factors. The time with the greatest number of fruits did not coincide with fruits of greater weight. The fertilizer study showed that the purple vinegar respond positively to organic ...

Local varieties are cultivated in agroecosystems.However, processes occur that may be causing genetic erosion of the species, running the risk of loss of varieties before knowing their potentials. The research of the thesis had as objectives to register and analyze in-situ conservation practices of the agrobiodiversity, to identify morphological descriptors that discriminate varieties, to develop identification keys for the varieties, to select varieties with favorable agronomic characteristics, to test the viability of hybrid seeds obtained from controlled pollinations and to evaluate the morphological diversity of the hybrid plants. Semi-structured interviews were conducted with the producers generating knowledge about the management of the in-situ agrobiodiversity. The diversity of varieties in the main production center of the Central Amazon region was raised using the snowball method. An experimental plantation with four randomized blocks and four plants per plot for 20 varieties was installed and evaluated the morphological diversityand agronomic characteristics. Sexual reproduction and seed germination were studied and carried out controlled pollinations between varieties and the hybrid plants generated were evaluated. Producer’s knowledge of diversity, propagation methods, exchange of propagating material and the local classification system of varieties were revealed. Morphological descriptors were identified that allowed the creation of an identification key for the aerial and subterranean parts of the local varieties studied. There were significant differences between the varieties in relation to the production of tubers and acceptance by the consumers, which allowed the identification of varieties with higher agronomic potential. Seed dormancy was confirmed and dormancy was broken bystorage (post-dispersion maturity). New genotypes were created by crossings that showed high phenotypic variability and tubers with new characteristics. The results provide tools for the conservation of agrobiodiversity and for genetic improvement, aiming at the rescue and valorization of the native food plants of the Amazon. / O cará (Dioscorea trifida L.) é uma planta alimentícia nativa da região amazônica. Diversas variedades locais são cultivadas nos agroecossistemas, porém, sujeitos aprocessos que podem estar causando erosão genética da espécie, correndo o risco de haver perdas de variedades antes que se possa reconhecer seus potenciais. A pesquisa que embasa a tese teve por objetivos registrar e analisar o conhecimento e as práticas a cerca da conservação in-situ da agrobiodiversidade do cará, identificar descritores morfológicos que discriminam variedades do cará, desenvolver uma chave de identificação para variedades, selecionar variedades com características agronômicas favoráveis, testar a viabilidade de sementes híbridas obtidas de polinizações controladas e avaliar a diversidade morfológica de plantas híbridas. Foram realizadas entrevistas semi-estruturadas com os produtores de cará gerando conhecimento sobre o manejo da agrobiodiversidade in-situ. A diversidade de variedades na principal região de produção do cará na Amazônia Central foi levantada com o método bola de neve. Foi instalado um plantio experimental com quatro blocos casualizados e quatro plantas por parcela com 20 variedades e realizada uma avaliação da diversidade morfológica e agronômica. Descritores morfológicos foram identificados que possibilitaram a criação de uma chave de identificação para as partes aéreas e subterrâneas das variedades estudadas. Houve diferencias significativos entre as variedades em relação à produção de tubérculos e aceitação pelos consumidores o que permitiu a identificação de variedades com elevado potencial agronômico. A dormência de sementes foi comprovada assim como a quebra da dormência após o armazenamento (maturidade pós-dispersão). Novos genótipos foram criados pelos cruzamentos que apresentaram alta variabilidade fenotípica e tubérculos com novas características. Os resultados fornecem ferramentas para a conservação da agrobiodiversidade e para o melhoramento genético, visando o resgate e a valorização das plantas alimentícias nativas da Amazônia.

Kan en lågfetthaltig växtbaserad diet få kranskärlsjukdomar att stagnera eller reversera? / Can a Low-Fat Plant-Based Diet Make Coronary Artery Diseases Stagnate or Reverse?

Teodorescu, Geanina January 2021 (has links)
Enligt Socialstyrelsen år 2019 var hjärt-och kärlsjukdomar den vanligaste dödsanledningen i Sverige och svarade för 31 % av alla dödsfall i landet. Akut kranskärlssjukdom tillhör hjärt- och kärlsjukdomar och är en folksjukdom som drabbar både kvinnor och män i hela västvärlden med högst mortalitet till följd. Kliniska studier har visat att den västerländska kosten med för högt animaliskt proteinintag, för högt intag av raffinerat socker och fett är den primära bakomliggande orsaken till dödsfall i hjärt-kärlsjukdom. Största riskfaktorn för kranskärl-och andra hjärtsjukdomar är arterioskleros (åderförkalkning). En växtbaserad 10 % lågfetthaltig Whole Food Plant Based-diet (WFPB) har visat sig ha en positiv effekt på arteriosklerosprocessen och vidare på hjärt-kärlsjukdomars utveckling. Syftet med detta projekt var att genom en systematisk litteraturstudie undersöka om hjärtsjukdomar, framförallt kranskärlsjukdomar (CAD) kan stagneras och/eller reverseras med hjälp av en lågfetthaltig WFPB-diet. Studien är baserad på 10 vetenskapliga artiklar framtagna ur databaserna CINAHL, PubMed, Google Scholar samt från referenslistan på två av de redan utvalda artiklarna. Samtliga tio artiklar som inkluderats i litteraturstudien valdes genom datainsamling, relevansbedömning och kvalitetsgranskning. För att säkerställa artiklarnas kvalité kvalitetsgranskades de relevanta artiklarna utifrån frågor skapade från en mall från Statens beredning för medicinsk och social utvärdering, SBU. De analyserade mätparametrarna i artiklarna var bl. a. angiografiparametrar, lipidbiomarkörer, anginasymtom, Flödesmedierat vasodilatationstest (FMD) samt Positronemissions tomografi (PET). De flesta granskade studierna visade reversering av CAD, två artiklar visade både reversering och stagnering och en artikel kunde inte bedömas. Stagnering eller reversering av kranskärlsjukdomar kan åstadkommas antingen genom en kombination av dietintervention och andra livstilförändringar som komplement till lipidsänkande medicinsk behandling eller genom endast diet-och andra livstilförändringar. / According to the National Board of Health and Welfare in 2019, cardiovascular disease was the most common cause of death in Sweden and accounted for 31% of all deaths in the country. Acute coronary heart disease belongs to cardiovascular disease and is a common disease that affects both women and men throughout the Western world with the highest mortality as a result. Clinical studies have shown that the Western diet with too high animal protein intake, too high intake of refined sugar and fat is the primary underlying cause of death in cardiovascular disease. The biggest risk factor for coronary heart disease and other heart diseases is arteriosclerosis (atherosclerosis). A plant-based 10% low-fat Whole Food Plant Based Diet (WFPB) has been shown to have a positive effect on the arteriosclerosis process and further on the development of cardiovascular disease. The purpose of this project was to investigate through a systematic literature study whether heart disease, especially coronary heart disease (CAD) can be stagnated and / or reversed with the help of a low-fat WFPB diet. The study is based on 10 scientific articles produced from the databases CINAHL, PubMed, Google Scholar and from the reference list of two of the already selected articles. All ten articles included in the literature study were selected through data collection, relevance assessment and quality review. To ensure the quality of the articles, the relevant articles were quality examined on the basis of questions created from a template from the Swedish Agency for Medical and Social Evaluation, SBU. The analyzed measurement parameters in the articles were for example angiography parameters, lipid biomarkers, angina symptoms, Flow-mediated vasodilation test (FMD) and Positron emission tomography (PET). Most of the studies examined showed reversal of CAD, two articles showed both reversal and stagnation and one article could not be assessed. Stagnation or reversal of coronary heart disease can be achieved either through a combination of dietary intervention and other lifestyle changes in addition to lipid-lowering medical treatment or through dietary and other lifestyle changes only.
