Resumo: | Tuber quality and sprouting are affected by the environmental conditions that the potato plants are subjected to during their developmental cycle. Despite the different environmental conditions between seasons and places, the thermal sum has been used to simulate plant developmental stages. In the case of potato, plant development also affects tuber maturity and post harvest behavior during storage. The objectives of this work were to evaluate the effect of accumulated thermal sum at different developmental phases of potato clones on sprouting and processing quality of tubers, for spring and autumn growing conditions, on central region of Rio Grande do Sul (state of Brazil), in different locations, storage temperature and size os tuber. We evaluated the emergency (EM), the tuber initiation (IT) and the onset of senescence (IS) of four potato clones (SMIJ461-1, SMINIA793101-3, SMINIA97145-2 and Macaca) produced in Santa Maria and Júlio de Castilhos during the spring and autumn seasons. We calculated the accumulated thermal sum (STa) for each phase. The tubers were stored at 10 and 20°C and evaluated for sprouting and processing quality at 0, 30, 60 and 90 days after the curing period. The percentage of sprouted tubers and the number of sprouts per tuber were assessed to evaluate dormancy and apical dominance of different sized tubers. The processing quality was assessed as the content of reducing sugars, dry matter, and starch and the percentage of fresh weight loses. The environmental conditions of spring and Júlio de Castilhos resulted in greater accumulation of STa, higher percentage of sprouted tubers, number of sprouts per tuber, percentage of fresh weight loses, dry mass and starch contents and lower content of reducing sugars than tubers produced in other environmental conditions. Despite the different environmental conditions of seasons and places that affected tuber maturity and physiological age, the accumulated thermal sum of the phases EM-IS or IT-IS can be used as indicative of sprouting and the starch and reducing sugars content. However, the physiological age and maturity at tuber harvesting is also correlated with tuber size, since tubers with diameter smaller than 35mm showed higher dormancy and apical dominance period, when compared to those with diameter larger than 35mm. |

Apesar das diferentes condições ambientais entre cultivos e locais, a temperatura tem sido amplamante utilizada como referencial para a estimativa do desenvolvimento vegetal, afetando, no caso da batata, tanto no período de desenvolvimento dos tubérculos, como no pós colheita. Os objetivos deste trabalho foram avaliar o efeito da soma térmica acumulada em diferentes fases do ciclo de desenvolvimento de clones de batata, na brotação e na qualidade de processamento dos tubérculos, para as condições de cultivo de primavera e outono, da região central do Rio Grande do Sul, em diferentes locais, temperaturas de armazenamento e tamanho de tubérculo. Foi determinada a emergência (EM), o início da tuberização (IT) e da senescência (IS) de quatro clones de batata (SMIJ461-1, SMINIA793101-3, SMINIA97145-2 e Macaca) produzidos a campo em Santa Maria e Júlio de Castilhos, durante os cultivos de primavera e outono e calculada a soma térmica acumulada (STa) em cada fase. Os tubérculos foram armazenados a 10 e 20ºC e avaliada a brotação e a qualidade de processamento ao 0, 30, 60 e 90 dias após o período de cura. A avaliação da brotação foi realizada a partir da porcentagem de tubérculos brotados e do número de brotos por tubérculo, sendo ainda avaliado o período de dormência e de dominância apical de diferentes tamanhos de tubérculo. A qualidade de processamento foi avaliada a partir das determinações de açúcares redutores, massa seca, amido e porcentagem de perda de massa fresca. As condições ambientais na primavera e em Júlio de Castilhos favoreceram maior acúmulo térmico, porcentagem e número de brotos por tubérculo, porcentagem de perda de massa fresca, teores de amido e massa seca e menores teores de açúcares redutores comparados com aqueles produzidos em outras condições. Apesar das diferenças de condições ambientais de épocas e locais de cultivo, que afetaram a maturidade e a idade fisiológica dos tubérculos, a soma térmica acumulada nas fases EM-IS ou IT-IS pode ser utilizada como indicativo da brotação e dos teores de amido e de açúcares redutores. No entanto, a maturidade e a idade fisiológica alcançada pelos tubérculos é também correlacionada com o tamanho, uma vez que aqueles com menor diâmetro inferior a 35mm apresentaram maior período de dormência e de dominância apical, quando comparado aqueles com menor diâmetro superior a 35mm.Coordenação de Aperfeiçoamento de Pessoal de Nível Superiorapplication/pdfporUniversidade Federal de Santa MariaPrograma de Pós-Graduação em AgronomiaUFSMBRAgronomiaSolanum tuberosum L.Massa secaAçúcares redutoresAmidoDormênciaSolanum tuberosum L.Dry weightReducing sugarsStarchDormancyCNPQ::CIENCIAS AGRARIAS::AGRONOMIASoma térmica na brotação e qualidade de tubérculos de batataThermal sum on sprouting and quality of potato tubersinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisBisognin, Dilson Antôniohttp://lattes.cnpq.br/7298261913496737Pereira, Arione da Silvahttp://lattes.cnpq.br/0047397375411458Augustin, Lizetehttp://lattes.cnpq.br/7422546534635532Streck, Nereu Augustohttp://lattes.cnpq.br/8121082379157248Brackmann, Aurihttp://lattes.cnpq.br/1305840929832646http://lattes.cnpq.br/5949317232072091Müller, Douglas Renato500100000009400300300300300300300e6bf95b7-0734-4760-a7af-f141d82b8525e235d331-0e57-4b96-9aa6-9b69170fbbb101cd8cae-202a-4866-8e67-21122ed4cac81bdf72db-aabf-4d0c-bbea-166cb38e54633dff1171-8f03-420f-87fc-f9fb10e5d8a2e6d627e7-3660-4771-a64c-9e3da0e009e1info:eu-repo/semantics/openAccessreponame:Manancial - Repositório Digital da UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALTESE Douglas Renato Muller.pdfapplication/pdf739232http://repositorio.ufsm.br/bitstream/1/3204/1/TESE%20Douglas%20Renato%20Muller.pdf25bb026caf18d25adc2ec23a9117a256MD51TEXTTESE Douglas Renato Muller.pdf.txtTESE Douglas Renato Muller.pdf.txtExtracted texttext/plain185692http://repositorio.ufsm.br/bitstream/1/3204/2/TESE%20Douglas%20Renato%20Muller.pdf.txtdf9f78151294b0657cadbe017e384107MD52THUMBNAILTESE Douglas Renato Muller.pdf.jpgTESE Douglas Renato Muller.pdf.jpgIM Thumbnailimage/jpeg4378http://repositorio.ufsm.br/bitstream/1/3204/3/TESE%20Douglas%20Renato%20Muller.pdf.jpg78319950889042bfa279dbabb82f3941MD531/32042023-06-15 13:03:27.715oai:repositorio.ufsm.br:1/3204Repositório Institucionalhttp://repositorio.ufsm.br/PUBhttp://repositorio.ufsm.br/oai/requestopendoar:39132023-06-15T16:03:27Manancial - Repositório Digital da UFSM - Universidade Federal de Santa Maria (UFSM)false |
