Resumo: | The objective of this work was to estimate cardinal temperatures and phyllochron for the leaf development of the eucalyptus species Corymbia citriodora and Eucalyptus urophylla, in the seedling phase. A field experiment was carried out in a completely randomized design, in a 2x11 factorial arrangement, with the two eucalyptus species, 11 sowing dates, and five replicates, in the municipality of Itajubá, in the state of Minas Gerais, Brazil. The cardinal temperatures – base, optimum, and maximum – for leaf development were, respectively, 8.7, 17.1, and 41.3°C, for C. citriodora, and 11.5, 17.1, and 40.5°C for E. urophylla. The phyllochron of C. citriodora was 62.95°C day per leaf, and that of E. urophylla was 46.03°C day per leaf, which indicates that E. urophylla requires less energy accumulation than C. citriodora for leaf emission in the main stem. |

Um experimento de campo foi realizado em delineamento inteiramente casualizado, em arranjo fatorial 2x11, com as duas espécies de eucalipto, 11 épocas de semeadura e cinco repetições, em Itajubá, MG. As temperaturas cardinais – basal inferior, ótima e basal superior – para o desenvolvimento foliar foram, respectivamente, 8,7, 17,1 e 41,3°C, para C. citriodora, e 11,5, 17,1 e 40,5°C, para E. urophylla. O filocrono de C.citriodora foi de 62,95°C dia por folha, e o de E. urophylla, de 46,03°C dia por folha, o que é indício de que E. urophylla necessita de menor acúmulo energético do que C. citriodora para a emissão de folhas na haste principal.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCoordenação de Aperfeiçoamento de Pessoal de Nível Superior (Capes, process No. 1115820)Freitas, Cleverson Henrique deMartins, Fabrina BolzanAbreu, Marcel Carvalho2017-06-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/23446Pesquisa Agropecuaria Brasileira; v.52, n.5, maio 2017; 283-292Pesquisa Agropecuária Brasileira; v.52, n.5, maio 2017; 283-2921678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/23446/13757https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/23446/15408Direitos autorais 2017 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2017-06-22T19:52:08Zoai:ojs.seer.sct.embrapa.br:article/23446Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2017-06-22T19:52:08Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
