Resumo: | Cucumis melo is one of the most important horticultural species representing the family Cucurbitaceae, moreover, it is the leader fruit concerning value and volume of exportation in Brazil. As in other cultures, both physiological and health quality of seeds used in the crop establishment are critical to ensure an appropriate population of plants and with high quality and productivity. Treatment of seeds is employed in order to protect them against pathogens, as well as, to accelerate and uniform their germination. Thus, this study aims to evaluate the physiological and health quality of melon seeds, cv. Gaúcho Redondo‟, treated with chemical fungicides, biocontrol agents, micronutrients and polymer. Application rates followed recommendations described by manufacturers. Evaluation of physiological traits was undertaken by means of germination, seedlings length, cold storage, germination at low temperatures, greenhouse emergence and emergence speed index tests. Health quality tests, by the other hand, were determined by Blotter test , transmission and pathogenicity of Fusarium spp. isolated from melon seeds. Treatments with micronutrients, purely or combined with polymer coating, incremented in seed germination, as well as, the emergence and the emergence speed index. Trichoderma spp. also provided a significant increase in the first count and germination. The fungicide Captan® acted efficiently on Fusarium spp. present in the seeds, though it had not been totally eradicated. This pathogen associated with melon seeds did not affect the germination process of them. |

Como em todas as culturas, a qualidade fisiológica e sanitária das sementes utilizadas na implantação da lavoura é fundamental para garantir uma população adequada de plantas e com elevada qualidade e produtividade. O tratamento de sementes é utilizado para promover a proteção das sementes contra patógenos causadores de doenças e proporcionar uma germinação mais rápida e uniforme. Dessa forma, o presente trabalho teve como objetivo avaliar a qualidade fisiológica e sanitária das sementes de melão, cultivar Gaúcho Redondo, após tratamento das mesmas com fungicidas químicos, agentes de biocontrole, micronutrientes e polímero. As doses de aplicação dos produtos seguiram as recomendações dos fabricantes e as avaliações da qualidade fisiológica das sementes foram realizadas através do teste de germinação, comprimento de plântulas, teste de frio, germinação a baixas temperaturas, emergência em casa de vegetação e índice de velocidade de emergência. Já a qualidade sanitária foi determinada pelo teste de sanidade, transmissão e patogenicidade de isolados de Fusarium spp. obtidos das sementes de melão. Os tratamentos com micronutrientes, isolados ou com recobrimento de polímero, promoveram incremento na germinação das sementes, assim como na emergência e no índice de velocidade de emergência. Trichoderma spp. também proporcionou aumento significativo na primeira contagem e na germinação. O fungicida Captan® atuou de forma eficiente no controle de Fusarium spp. presente nas sementes, embora não tenha erradicado totalmente. Este patógeno, associado às sementes de melão, não interferiu no processo germinativo das mesmas.Coordenação de Aperfeiçoamento de Pessoal de Nível Superiorapplication/pdfporUniversidade Federal de Santa MariaPrograma de Pós-Graduação em AgronomiaUFSMBRAgronomiaMicronutrientesTrichoderma spp.Recobrimento de sementesMicronutrientsSeed coatingCNPQ::CIENCIAS AGRARIAS::AGRONOMIATratamentos de sementes de melão e os efeitos sobre a qualidade sanitária e fisiológicaTreatment melon seeds and the effects on health and physiological qualityinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisMuniz, Marlove Fatima Briãohttp://lattes.cnpq.br/3148312031889388Silva, Magnolia Aparecida Silva dahttp://lattes.cnpq.br/8227973991742116Nunes, Ubirajara Russihttp://lattes.cnpq.br/8937125213120268http://lattes.cnpq.br/9775777422791792Müller, Juceli500100000009400500300300500e8de5014-a63f-4739-8254-6b23c08bcd5994edbab7-934b-4bc5-b74f-668251ada99af0eedded-89d6-4b02-a895-0c845c33eaf75d1edb2d-76d4-497a-946f-d4ba747059f3info:eu-repo/semantics/openAccessreponame:Manancial - Repositório Digital da UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALMULLER, JUCELI.pdfapplication/pdf1421893http://repositorio.ufsm.br/bitstream/1/5101/1/MULLER%2c%20JUCELI.pdf879cb0122071522571b4cd9f3036c639MD51TEXTMULLER, JUCELI.pdf.txtMULLER, JUCELI.pdf.txtExtracted texttext/plain203710http://repositorio.ufsm.br/bitstream/1/5101/2/MULLER%2c%20JUCELI.pdf.txt746976877d5d16e0b341d9f21869a0e9MD52THUMBNAILMULLER, JUCELI.pdf.jpgMULLER, JUCELI.pdf.jpgIM Thumbnailimage/jpeg4812http://repositorio.ufsm.br/bitstream/1/5101/3/MULLER%2c%20JUCELI.pdf.jpgbd7221a24bb2db0b2583f2a94f9b5134MD531/51012022-07-12 11:02:01.165oai:repositorio.ufsm.br:1/5101Repositório Institucionalhttp://repositorio.ufsm.br/PUBhttp://repositorio.ufsm.br/oai/requestopendoar:39132022-07-12T14:02:01Manancial - Repositório Digital da UFSM - Universidade Federal de Santa Maria (UFSM)false |
