Resumo: The objective of this work was to evaluate the thermal requirement, obtained by different thermal time calculation methods, to characterize the grapevine (Vitis vinifera) phenology of 'Cabernet Sauvignon', 'Tannat', 'Ruby Cabernet', and 'Merlot' grown in the Fronteira Oeste region, of the state of Rio Grande do Sul, Brazil. The phenological development was followed for five seasons – 2005/2006 to 2009/2010. Minimum and maximum air temperatures were recorded daily, and the following eight thermal time methods were tested: M1.1, M1.2, and M1.3, which use only the down threshold temperature (10°C); M2.1 and M2.2, which also consider 25°C as the optimum temperature for development; and M3.1, M3.2, and M3.3, which, besides using the prior temperatures, consider 35°C as the upper threshold temperature of development. These methods were compared using the standard error (SE) estimates of accumulated heat. The SNK test was used to compare the thermal requirement between cultivars. M3.3 was the method that best simulated 'Tannat' and 'Merlot' development (1,823.1 and 1,780.8 degree‑day respectively). However, the least deviation was obtained in 'Cabernet Sauvignon' and 'Ruby Cabernet' using the M3.1 method (1,958.9 and 1,944.8 degree‑ day respectively). Methods employing the three cardinal temperatures showed greater accuracy. 'Tannat' and 'Merlot' are the cultivars that show the lowest thermal requirement to complete the cycle.

O desenvolvimento fenológico foi acompanhado durante cinco safras – 2005/2006 a 2009/2010. As temperaturas mínimas e máximas do ar foram coletadas diariamente e foram testados oito métodos de soma térmica: M1.1, M1.2 e M1.3, que utilizaram somente a temperatura base inferior (10°C); M2.1 e M2.2, que consideraram também a temperatura ótima de desenvolvimento de 25°C; e M3.1, M3.2 e M3.3 que, além das anteriores, utilizaram 35°C como temperatura base superior do desenvolvimento. Estes métodos foram comparados pelo erro‑padrão das estimativas de soma térmica. O teste SNK foi utilizado para a comparação da exigência térmica entre as cultivares. O método M3.3 foi o que melhor simulou o desenvolvimento em 'Tannat' e 'Merlot' (1.823,1 e 1.780,8 graus‑dia respectivamente). No entanto, o menor desvio foi obtido em 'Cabernet Sauvignon' e 'Ruby Cabernet', pelo método M3.1 (1.958,9 e 1.944,8 graus‑dia respectivamente). Os métodos que empregaram as três temperaturas cardinais apresentaram maior precisão. 'Tannat' e 'Merlot' são as cultivares de videira que apresentam a menor exigência térmica para completar o ciclo.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraTomazetti, Tiago CamponogaraRossarolla, Márcia DeniseZeist, André RicardoGiacobbo, Clevison LuizWelter, Leocir JoséAlberto, Cleber Maus2015-12-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/21331Pesquisa Agropecuaria Brasileira; v.50, n.11, nov. 2015; 1033-1041Pesquisa Agropecuária Brasileira; v.50, n.11, nov. 2015; 1033-10411678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/21331/13117Direitos autorais 2015 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2015-12-09T18:15:31Zoai:ojs.seer.sct.embrapa.br:article/21331Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2015-12-09T18:15:31Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
