Resumo: | Rare earth elements, or lanthanides, are commonly applied to plants at Chinese agriculture, as fertilizers. Brazil doesn t have any appointment of it utilization in agriculture. Experiments were conduced to evaluate effects of rare earth elements, cerium (Ce) and lanthanum (La), on seeds physiological quality of lettuce, corn, bean and soybean, growth and development of corn and soybean plants then seed treatment with this elements. For this, seeds of different species, on separated experiments, were treated for immersion in watery solutions of Ce or La, in different concentrations, for one or two hours. Were applied, at laboratory, tests of germination, first counting of germination, vigor classification of seedlings, seedlings length, dry mass and thermal stress. The experimental design was completely randomized with treatments composed of Ce or La concentrations and four replications. For corn and soybean were installed experiments at field. Were evaluated: emergency (corn and soybean), leaf number, height, diameter of colm, bloom and yield (in maize). Treatments were composed of different Ce or La concentrations and four replications. Results shows that Ce and La application at seeds influenced, in the majority of the cases, germination and vigor of seedlings. Seedlings length and dry mass were influenced by elements. Ce and La were absorbed by seeds and translocated to seedlings. At field didn t observe effects of Ce and La at corn growth and development, and at soybean emergency, but Ce treatment increased corn yield. |

No Brasil não há qualquer registro de sua utilização na agricultura. Conduziram-se experimentos com o objetivo de avaliar os efeitos dos elementos terras raras, cério (Ce) e lantânio (La), sobre a qualidade fisiológica de sementes de alface, milho, feijão e soja e; crescimento e desenvolvimento de plantas de milho e soja após tratamento das sementes com os elementos. Para tal, as sementes das diferentes espécies, em experimentos separados, foram tratadas por meio de imersão em soluções aquosas de Ce ou de La, em diferentes concentrações, por uma a duas horas. Em seguida, foram aplicados, em laboratório, os testes de germinação, primeira contagem de germinação, classificação do vigor de plântulas, comprimento, massa seca de plântulas e estresse térmico. Os tratamentos foram compostos por diferentes concentrações de Ce ou La e quatro repetições. Em milho e soja foram instalados experimentos em campo. Após o tratamento das sementes foram avaliados: emergência (em milho e soja), número de folhas, estatura, diâmetro do colmo, florescimento e rendimento (em milho). Os resultados mostraram que a aplicação de Ce e La nas sementes influenciou, na maioria dos casos, a germinação e o vigor. O comprimento e a massa seca das plântulas também responderam a aplicação dos elementos. Para todas as espécies, tanto o Ce quanto o La foram absorvidos pelas sementes em solução aquosa e ocorreu translocação para as plântulas. Em campo não foram observados efeitos do Ce e do La sobre o crescimento e desenvolvimento de plantas de milho e sobre a emergência da soja, mas, o tratamento com Ce foi capaz de aumentar o rendimento final da cultura do milho.Coordenação de Aperfeiçoamento de Pessoal de Nível Superiorapplication/pdfporUniversidade Federal de Santa MariaPrograma de Pós-Graduação em AgronomiaUFSMBRAgronomiaLantanídeosGerminaçãoVigorCrescimentoDesenvolvimentoNutrição de plantasMicronutrientesLanthanidesGerminationVigorGrowthDevelopmentPlant nutritionMicronutrientsCNPQ::CIENCIAS AGRARIAS::AGRONOMIATratamento de sementes de alface, milho, soja e feijão com os elementos terras raras cério e lantânioLetuce, corn, soybean and bean seeds treatment with rare earth elements cerium and lanthanuminfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisMenezes, Nilson Lemos dehttp://lattes.cnpq.br/0551755093817460Storck, Lindolfohttp://lattes.cnpq.br/7538496041313334Muniz, Marlove Fátima Briãohttp://lattes.cnpq.br/3148312031889388Franzin, Simone Medianeirahttp://lattes.cnpq.br/9408955824479246Villela, Francisco Amaralhttp://lattes.cnpq.br/6923504145358889http://lattes.cnpq.br/2626524403492935Espindola, Maria Carolina Grigoletto500100000009400300300300300300300e192fb92-c217-40e7-b68b-b865c4403abba4044f8b-dacb-43cf-8778-9f3d8ba3c4021da63f63-00ac-4d75-8280-386c6408637cfac7d9a2-a25b-42d4-98a7-0bb1c27df1ef1ef02755-4496-43a0-a10b-d46e4cfa917e4472a124-1986-43c8-a989-3d44fc4529cainfo:eu-repo/semantics/openAccessreponame:Biblioteca Digital de Teses e Dissertações do UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALESPINDOLA, MARIA CAROLINA GRICOLETTO.pdfapplication/pdf547252http://repositorio.ufsm.br/bitstream/1/3179/1/ESPINDOLA%2c%20MARIA%20CAROLINA%20GRICOLETTO.pdffd31758146836bdd06cff265f7d2a221MD51TEXTESPINDOLA, MARIA CAROLINA GRICOLETTO.pdf.txtESPINDOLA, MARIA CAROLINA GRICOLETTO.pdf.txtExtracted texttext/plain145779http://repositorio.ufsm.br/bitstream/1/3179/2/ESPINDOLA%2c%20MARIA%20CAROLINA%20GRICOLETTO.pdf.txtebbe07051055aad1edc2776d80f30b46MD52THUMBNAILESPINDOLA, MARIA CAROLINA GRICOLETTO.pdf.jpgESPINDOLA, MARIA CAROLINA GRICOLETTO.pdf.jpgIM Thumbnailimage/jpeg5175http://repositorio.ufsm.br/bitstream/1/3179/3/ESPINDOLA%2c%20MARIA%20CAROLINA%20GRICOLETTO.pdf.jpg232c9ba8ebcbfecd63b964ac152a2e78MD531/31792022-08-08 10:14:23.777oai:repositorio.ufsm.br:1/3179Biblioteca Digital de Teses e Dissertaçõeshttps://repositorio.ufsm.br/ONGhttps://repositorio.ufsm.br/oai/requestatendimento.sib@ufsm.br||tedebc@gmail.comopendoar:2022-08-08T13:14:23Biblioteca Digital de Teses e Dissertações do UFSM - Universidade Federal de Santa Maria (UFSM)false |
