Resumo: | The objective of this work was to estimate the base temperature for node emission and plastochron determination in wild species of tomato, in the Redenção cultivar, and in their respective interspecific F1 hybrids. The wild accessions Solanum pimpinellifolium AF 26970, Solanum galapagense LA-1401, Solanum peruvianum AF 19684, Solanum habrochaites var. hirsutum PI-127826, Solanum habrochaites var. glabratum PI-134417, and Solanum pennellii LA-716; the cultivar Redenção (Solanum lycopersicum); and their respective interspecific hybrids were evaluated, on the transplanting dates 12/22/2015, 2/12/2016, and 4/6/2016. The base temperature was estimated using the least mean squared error of the linear regression between the number of nodes and the accumulated thermal sum. The plastochron for the main stem and the first three lateral stems was estimated using the base temperature. The base temperature for node emission and plastochron determination varied from 4.5 to 14.8°C. The species S. habrochaites var. hirsutum accession PI-127826, S. habrochaites var. glabratum accession PI-134417, and their hybrids with the Redenção cultivar showed the lowest base temperatures and plastochron for the main stem, whereas the remaining wild species and interspecific hybrids had a base temperature near that of cultivated tomato. Wild species and interspecific hybrids of tomato show a great variation in base temperature for node emission and plastochron determination. |

Avaliaram-se os acessos silvestres Solanum pimpinellifolium AF 26970, Solanum galapagense LA-1401, Solanum peruvianum AF 19684, Solanum habrochaites var. hirsutum PI-127826, Solanum habrochaites var. glabratum PI-134417 e Solanum pennellii LA-716; a cultivar Redenção (Solanum lycopersicum); e os seus respectivos híbridos interespecíficos, nas datas de transplantio 22/12/2015, 12/2/2016 e 6/4/2016. A temperatura-base foi estimada com o método do menor quadrado médio do erro da regressão linear entre o número de nós e a soma térmica acumulada. O plastocrono para a haste principal e as três primeiras hastes laterais foi estimado com uso da temperatura-base. A temperatura base para emissão de nós e determinação do plastocrono variou entre 4,5 e 14,8°C. As espécies S. habrochaites var. hirsutum acesso PI-127826, S. habrochaites var. glabratum acesso PI-134417 e os respectivos híbridos com a cultivar Redenção apresentaram os menores valores de temperatura‑base e plastocrono da haste principal, enquanto as demais espécies silvestres e os híbridos interespecíficos tiveram temperatura-base próxima à do tomateiro cultivado. As espécies silvestres e os híbridos interespecíficos de tomate mostram grande variação na temperatura-base para emissão de nós e determinação do plastocrono.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCoordenação de Aperfeiçoamento de Pessoal de Nível Superior (Capes)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Centro de Investigación Científica de Yucatán (CICY)Zeist, André RicardoResende, Juliano Tadeu Vilela deFaria, Marcos VenturaGabriel, AndréSilva, Israel Felipe Lustosa daLima Filho, Renato Barros de2018-05-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/25573Pesquisa Agropecuaria Brasileira; v.53, n.3, mar. 2018; 307-315Pesquisa Agropecuária Brasileira; v.53, n.3, mar. 2018; 307-3151678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/25573/14149https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/25573/17300Direitos autorais 2018 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2018-05-08T11:31:42Zoai:ojs.seer.sct.embrapa.br:article/25573Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2018-05-08T11:31:42Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
