Resumo: | The objective of this research was: a) evaluate the effect of imidazolinone chemical group herbicides on the growth of plants and the injuries to the photosynthetic apparatus of three rice types (varieties) exposed to these and b) evaluate the effect of soil residual herbicides imazethapyr+ imazapic on corn, cucumber, radish and tomato are used as bioindicators. At first experiments we used the herbicide Only® and Kifix®, using a randomized split plot design in a factorial 5x3 with six replications, with the first factor rates corresponded to 0, 5, 10, 15 and 20 mg p. c. m-2 of commercial product Only® and 0, 7, 14, 21 and 28 mg p. c. m-2 of commercial product Kifix®, and factor B type of rice (cultivated rice cv. Puitá Inta CL, red rice ecotype sensitive to herbicides Imidazolinone and red rice ecotype with suspected herbicide tolerance imidazolinone). We evaluated the parameters of chlorophyll a fluorescence, phytotoxicity, plant height and dry mass. Analysis of chlorophyll a fluorescence was performed using a portable fluorometer (HandyPEA, Hanstech). It was concluded that cv. Puitá Inta CL is tolerant to herbicides Only® and Kifix® and can be used in the Clearfield® system and the red rice ecotype with suspected tolerance was tolerant to both herbicides, suffering a low phytotoxity compared to the sensitive ecotype, even using higher doses of the commercial products. The application of chemical herbicides of the imidazolinone group in rice plants cause changes in the photosynthetic metabolism of plants that can be detected by evaluating the emission of chlorophyll a fluorescence transient. The second experiment was conducted in a randomized block experimental design (with) four replicates per treatment. The treatments were the residual effect of herbicide Only® in rice CL plants in the 2006/2007 harvest, at 0, 10, 15 and 20 mg p. c. m-2 doses of commercial product, on four bioindicators: corn, cucumber, radish and tomato. The variables evaluated were: height, dry weight of shoot and root dry mass, with the latter doesn t being performed for the corn plants. Data of biometric variables generated in both experiments were subjected to analysis of variance (p ≤ 0.05) were significant in these models were tested by polynomial regression. Activity was detected in the commercial mixture of residual herbicides imazethapyr +imazapic in soil 1100 days after herbicide application, by use of bioindicators plants. |

No primeiro ensaio foram utilizados os herbicidas Only® e Kifix®, utilizando-se para cada herbicida um delineamento experimental de parcelas subdivididas, em esquema fatorial 5x3, com seis repetições, sendo o fator A as doses do herbicida correspondentes a 0, 5, 10, 15 e 20 mg p. c. m-2 do produto comercial Only® e 0, 7, 14, 21 e 28 mg p. c. m-2 do produto comercial Kifix®, e o fator B o tipo de arroz (arroz cultivado cv. Puitá Inta CL, ecótipo de arroz-vermelho sensível aos herbicidas do grupo das imidazolinonas e ecótipo de arroz-vermelho com suspeita de tolerância aos herbicidas do grupo das imidazolinonas). Foram avaliados os parâmetros da fluorescência da clorofila a, fitotoxicidade, altura de plantas e massa seca da parte aérea. A análise da fluorescência da clorofila a foi realizada utilizando-se um fluorômetro portátil (HandyPEA, Hanstech).Conclui-se que a cv. Puitá Inta CL é tolerante aos herbicidas Only® e Kifix®, podendo ser utilizada no Sistema de Produção Clearfield® e que o ecótipo de arroz-vermelho com suspeita de tolerância apresentou tolerância a ambos herbicidas, sofrendo baixa fitotoxicidade em comparação ao ecótipo sensível, mesmo utilizando-se doses superiores as comerciais dos produtos. A aplicação de herbicidas do grupo químico das imidazolinonas em plantas de arroz causa alterações no metabolismo fotossintético das plantas que podem ser detectadas através da avaliação da emissão da fluorescência da clorofila a transiente. O segundo experimento foi conduzido em um delineamento experimental casualizado por bloco, totalizando quatro repetições por tratamento. Os tratamentos avaliados foram o efeito residual do herbicida Only® sob as plantas de arroz CL na safra 2006/2007, nas doses de doses de 0, 10, 15 e 20 mg p. c. m-2 do produto comercial, sobre quatro espécies bioindicadoras: milho, pepino, rabanete e tomate. Foram avaliadas as variáveis: altura de plantas, massa seca da parte aérea e massa seca das raízes, sendo esta última não realizada para as plantas de milho. Os dados relativos às variáveis biométricas gerados em ambos os experimentos foram submetidos à análise da variância (p≤0,05); em sendo significativos, estes foram testados por modelos de regressão polinomial. Foi detectada atividade residual da mistura comercial dos herbicidas imazethapyr+imazapic em solo após 1100 dias da aplicação dos herbicidas, pelo uso de plantas bioindicadoras.application/pdfporUniversidade Federal de PelotasPrograma de Pós-Graduação em Fisiologia VegetalUFPelBRBiologiaInibidores ALSOnly®Kifix®Oryza sativa L.Teste JIPALS-inhibitingOnly®Kifix®Oryza sativa L.JIP-testCNPQ::CIENCIAS BIOLOGICAS::BOTANICA::FISIOLOGIA VEGETALCrescimento de plantas de arroz sob aplicação de herbicidas do grupo das imidazolinonas e sua atividade residual em plantas bioindicadorasGrowth of rice plants under application of herbicides imidazolinone and its residual activity in bioindicators plantsinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesishttp://lattes.cnpq.br/3934515090201644http://lattes.cnpq.br/9778741221243155Pinto, Jesus Juares Oliveirahttp://lattes.cnpq.br/4493535698894302Lopes, Nei Fernandeshttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4788217T1Bacarin, Marcos AntônioSousa, Camila Pinho deinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFPel - Guaiacainstname:Universidade Federal de Pelotas (UFPEL)instacron:UFPELORIGINALdissertacao_camila_sousa.pdfapplication/pdf1105338http://guaiaca.ufpel.edu.br/xmlui/bitstream/123456789/2032/1/dissertacao_camila_sousa.pdf6a0e449f6b57375f68a8ff703e00bf3cMD51open accessTEXTdissertacao_camila_sousa.pdf.txtdissertacao_camila_sousa.pdf.txtExtracted Texttext/plain125872http://guaiaca.ufpel.edu.br/xmlui/bitstream/123456789/2032/2/dissertacao_camila_sousa.pdf.txtbf199dcc3229b6d2454de99193f2dcb9MD52open accessTHUMBNAILdissertacao_camila_sousa.pdf.jpgdissertacao_camila_sousa.pdf.jpgGenerated Thumbnailimage/jpeg1321http://guaiaca.ufpel.edu.br/xmlui/bitstream/123456789/2032/3/dissertacao_camila_sousa.pdf.jpg361ad62e5cf83c5ffc2bb4822e6954a1MD53open access123456789/20322019-09-09 11:13:31.082open accessoai:guaiaca.ufpel.edu.br:123456789/2032Repositório InstitucionalPUBhttp://repositorio.ufpel.edu.br/oai/requestrippel@ufpel.edu.br || repositorio@ufpel.edu.br || aline.batista@ufpel.edu.bropendoar:2019-09-09T14:13:31Repositório Institucional da UFPel - Guaiaca - Universidade Federal de Pelotas (UFPEL)false |
