Resumo: Temperature can exert great influence on germination, being considered optimal the temperature in which seed expresses its maximum germination potential in the shortest period of time. The germination of parsley seeds is slow, irregular and uneven. The aim of this study was to determine whether there is occurrence of thermodormancy or thermoinhibition of parsley seeds as a function of temperature variations. The experimental design of the first stage was completely randomized (CRD) consisting of 7 temperatures and 4 replicates and the second stage in a 3x3 factorial scheme consisting of 3 parsley cultivars and 3 germination temperatures with 4 replicates. Seeds of the different cultivars did not germinate at temperature of 35°C. Parsley seeds showed thermoinhibition at high temperatures, being necessary to elucidate the mechanisms involved in this process.

A germinação das sementes de salsa é lenta, irregular e desuniforme. O objetivo do trabalho foi determinar se há ocorrência de termodormência ou de termoinibição em sementes de salsa em função da variação da temperatura. O delineamento experimental da primeira etapa foi inteiramente casualizado (DIC), constituído por 7 temperaturas, com 4 repetições e a segunda etapa em esquema fatorial 3x3, constituído por 3 cultivares de salsa e 3 temperaturas para germinação com 4 repetições. As sementes das cultivares estudadas não germinaram em temperaturas de 35°C. Sementes de salsa apresentam termoinibição em temperaturas elevadas, sendo necessário elucidar os mecanismos que estão envolvidos nesse processo.EDUFU2017-11-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/3719210.14393/BJ-v33n6a2017-37192Bioscience Journal ; Vol. 33 No. 6 (2017): Nov./Dec.; 1412-1418Bioscience Journal ; v. 33 n. 6 (2017): Nov./Dec.; 1412-14181981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/37192/21151Brazil; ContemporaryCopyright (c) 2017 Tiago Alexandre da Silva, Luiz Felipe Guedes Baldini, Gisela Ferreira, João Nakagawa, Edvaldo Aparecido Amaral da Silvahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSilva, Tiago Alexandre daBaldini, Luiz Felipe GuedesFerreira, GiselaNakagawa, Joãoda Silva, Edvaldo Aparecido Amaral2022-02-11T17:48:45Zoai:ojs.www.seer.ufu.br:article/37192Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-02-11T17:48:45Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false
