Resumo: The objective of this work was to evaluate growth and dry matter accumulation and distribution of potato cultivars (Solanum tuberosum) Ágata, Asterix, Atlantic, Markies, and Mondial, during the winter crop season. The experiment was carried out in Itaí, São Paulo state, Brazil, from June to October 2008. A randomized complete block design with split-plots and four replications was used. Plots comprised the potato cultivars and subplots were established by plant sampling times: at planting and every seven days after emergence. All the cultivars show slow growth until the onset of the tuber bulking stage. However, Asterix, Atlantic and Markies are earlier than Mondial in obtaining the maximum rates of dry matter accumulation. The Asterix and Mondial cultivars have more leaves per plant, higher tuber yield, higher maximum accumulation rates and dry matter production, but Mondial is less efficient in dry matter alocation to the tubers than the other cultivars. The cultivars with higher maximum accumulation rates provided higher amounts of dry matter, even with shorter terms of the maximum accumulation rate.

O experimento foi conduzido de junho a outubro de 2008, no munícipio de Itaí, SP. Utilizou-se o delineamento experimental de blocos ao acaso, em parcelas subdivididas, com quatro repetições. As parcelas foram constituídas pelas cultivares, e as subparcelas por épocas de coletas de plantas para avaliação: no plantio e a cada sete dias após a emergência. Todas as cultivares têm crescimento lento até o início da fase de enchimento de tubérculos. Porém, as cultivares Asterix, Atlantic e Markies são mais precoces do que a Mondial no estabelecimento de taxas máximas de acúmulo de matéria seca. As cultivares Asterix e Mondial apresentam maior número de folhas por planta, produtividade de tubérculos, taxa de acúmulo e produção de MS, mas a cultivar Mondial é menos eficiente na alocação de MS nos tubérculos que as demais cultivares. As cultivares com maior taxa máxima de acúmulo produzem maior quantidade de MS, mesmo apresentando menor período de duração da taxa máxima de acúmulo.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFernandes, Adalton MazettiSoratto, Rogério PeresSilva, Beatrice LucianaSouza-Schlick, Genivaldo David de2011-01-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/8196Pesquisa Agropecuaria Brasileira; v.45, n.8, ago. 2010; 826-835Pesquisa Agropecuária Brasileira; v.45, n.8, ago. 2010; 826-8351678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/8196/6079https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/8196/3850info:eu-repo/semantics/openAccess2014-11-07T19:18:30Zoai:ojs.seer.sct.embrapa.br:article/8196Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-11-07T19:18:30Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
