Resumo: | Global climate change causes stresses that can limit crop productivity and threaten food production in the future. Increased production implies an increase in the demand for water, with irrigation being the activity that most uses fresh water today. The culture of rice represents an important staple food and effects of the increase in atmospheric CO2 atmospheric can affect development and production, in addition to affecting weedy rice, the most important weed in flooding rice system. Therefore, the present research aimed to evaluate the effect of increasing CO2 atmospheric associated with different water regimes on rice and weedy rice. For this, experiments were carried out to evaluate development and water use efficiently in rice crop and also, quantify the total concentration of arsenic and cadmium in grains; the effects in weedy rice growth, development, seed shattering and longevity of seed bank; the gene expression to genes to be related to involve on seed shattering in rice, and to evaluated on the quality of grains and physicochemical proprieties in rice and red rice. The results allowed indicated that increase in CO2 affects the growth, development and water use efficiency in rice. In addition, in the assessment of total arsenic, intermittent regime decreased the absorption of the element. Considering the studies development with weedy rice, the effect of increase CO2 was observed for growth and development, in addition to increasing the seed shattering and seed viability at seedbank. In addition, gene expression demonstrated that the genes OsCPL1, qSH1, SHAT1, OsXTH8, OSH15 and SH5 are affected by the increase in CO2, making the characteristic more complex because involver several metabolic pathways. Contemplating the grain yield analysis, white rice had a decrease in head rice yield in high CO2, in addition an increase in the chalkiness area and a decrease in crude protein, with changes in cooking parameters. These results contribute to characterization of increase CO2 in rice crop, being the basis for future studies, which continue in search to elucidate the effects of climate change in agriculture, assisting in the planning of the adoption of sustainable management, in order to minimize the negative effects. |

Aumento da produção implica no aumento da demanda por água, sendo que a irrigação é a atividade que mais utiliza água doce atualmente. A cultura do arroz (Oryza sativa) representa importante alimento básico para população mundial e os efeitos do aumento de CO2 atmosférico podem afetar seu desenvolvimento e produção, além de afetar o arroz daninho, uma das principais plantas daninhas na cultura do arroz. Diante disso, a presente pesquisa teve como principal objetivo avaliar o efeito do aumento da concentração atmosférica de CO2 (400 e 700 μmol mol-1 ) associada a diferentes regimes hídricos (contínuo e intermitente) em arroz e arroz daninho. Para isso, estudos foram desenvolvidos para avaliar parâmetros de crescimento e produtivo, eficiência no uso da água pela cultura do arroz e quantificar o total de arsênio e cádmio nos grãos; efeito nos parâmetros de crescimento e produtivo de arroz daninho, bem como o degrane e a viabilidade de sementes no banco de sementes; expressão gênica de genes associados ao processo de degrane; e avaliar o rendimento de grãos e propriedades físico-químicas de arroz branco e vermelho. Os resultados permitiram inferir que o aumento do CO2 afeta o crescimento, desenvolvimento e a eficiência do uso da água em arroz. Além disso, na avaliação de arsênio total, o regime intermitente diminuiu a absorção do elemento. Considerando os estudos realizados com arroz daninho, o efeito do CO2 foi observado para crescimento e desenvolvimento, além de aumentar a taxa de degrane e a viabilidade de sementes no banco de sementes do solo. Em adição, a expressão gênica demonstrou que os genes OsCPL1, qSH1, SHAT1, OsXTH8, OSH15 e SH5 são afetados pelo aumento do CO2, tornando a característica ainda mais complexa, visto que o CO2 tem ação em diversas rotas metabólicas. Contemplando a análise de rendimento de grãos, o arroz branco teve diminuição no rendimento de inteiros em alto CO2, além de aumento na área gessada e diminuição da proteína bruta, com alterações nos parâmetros de cocção. Estes resultados auxiliam na caracterização das implicações do aumento de CO2 na cultura do arroz sendo base para estudos futuros, que seguem na busca em elucidar os efeitos das mudanças climáticas na agricultura, auxiliando no planejamento da adoção de manejo sustentável, de modo a minimizar os efeitos negativos.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPESporUniversidade Federal de PelotasPrograma de Pós-Graduação em FitossanidadeUFPelBrasilFaculdade de Agronomia Eliseu MacielCNPQ::CIENCIAS AGRARIAS::AGRONOMIA::FITOSSANIDADEClimate changeWater regimesWater use efficientlyRice shatteringPhenolic compoundsHead yield riceMudança climáticaRegimes hídricosEficiência do uso da águaDegrane de arrozCompostos fenólicosRendimento de grãosEffect of enhanced CO2 atmospheric concentration on rice and weedy riceEfeito do aumento da concentração de CO2 atmosférico na cultura do arroz e no arroz daninhoinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesishttp://lattes.cnpq.br/9480404753456469http://lattes.cnpq.br/5245663326931142Kruse, Nelson Diehlhttp://lattes.cnpq.br/1755736441490062Camargo, Edinalvo Rabaiolihttp://lattes.cnpq.br/1423135119732932Avila, Luis Antonio deBalbinot, Andrisainfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFPel - Guaiacainstname:Universidade Federal de Pelotas (UFPEL)instacron:UFPELTEXTBalbinot.pdf.txtBalbinot.pdf.txtExtracted texttext/plain11840http://guaiaca.ufpel.edu.br/xmlui/bitstream/prefix/8380/6/Balbinot.pdf.txt4f06296b0de11e670cfd9824ffcf7b7aMD56open accessTHUMBNAILBalbinot.pdf.jpgBalbinot.pdf.jpgGenerated Thumbnailimage/jpeg1185http://guaiaca.ufpel.edu.br/xmlui/bitstream/prefix/8380/7/Balbinot.pdf.jpg5d884de7383f64ad7668157aaea7ecd5MD57open accessORIGINALBalbinot.pdfBalbinot.pdfapplication/pdf142858http://guaiaca.ufpel.edu.br/xmlui/bitstream/prefix/8380/1/Balbinot.pdf5059592afc75149ed544b8387c5c1886MD51open accessCC-LICENSElicense_urllicense_urltext/plain; charset=utf-849http://guaiaca.ufpel.edu.br/xmlui/bitstream/prefix/8380/2/license_url924993ce0b3ba389f79f32a1b2735415MD52open accesslicense_textlicense_texttext/html; charset=utf-80http://guaiaca.ufpel.edu.br/xmlui/bitstream/prefix/8380/3/license_textd41d8cd98f00b204e9800998ecf8427eMD53open accesslicense_rdflicense_rdfapplication/rdf+xml; charset=utf-80http://guaiaca.ufpel.edu.br/xmlui/bitstream/prefix/8380/4/license_rdfd41d8cd98f00b204e9800998ecf8427eMD54open accessLICENSElicense.txtlicense.txttext/plain; charset=utf-867http://guaiaca.ufpel.edu.br/xmlui/bitstream/prefix/8380/5/license.txtfbd6c74465857056e3ca572d7586661bMD55open accessprefix/83802023-07-13 03:47:33.818open accessoai:guaiaca.ufpel.edu.br:prefix/8380VG9kb3Mgb3MgaXRlbnMgZGVzc2EgY29tdW5pZGFkZSBzZWd1ZW0gYSBsaWNlbsOnYSBDcmVhdGl2ZSBDb21tb25zLg==Repositório InstitucionalPUBhttp://repositorio.ufpel.edu.br/oai/requestrippel@ufpel.edu.br || repositorio@ufpel.edu.br || aline.batista@ufpel.edu.bropendoar:2023-07-13T06:47:33Repositório Institucional da UFPel - Guaiaca - Universidade Federal de Pelotas (UFPEL)false |
