Resumo: | The objective of this work was to assess the effect of solar radiation, air temperature and photoperiod, in plant development and yield of potato clones grown under spring and autumn conditions. The clones SMIJ461-1, SMINIA793101-3, SMINIA97145-2 and the cultivar Macaca were cultivated during spring 2006 and autumn 2007, in Santa Maria, RS, Brazil. Leaf number at tuber initiation and at final tuberization, phylochron, accumulated thermal sum from emergence to tuber initiation and from tuber initiation to beginning of senescence, and yield were determined. The conditions of temperature and photoperiod affected accumulated thermal sum of emergence–tuber initiation and tuber initiation–beginning of senescence, yield and leaf number at tuber initiation, but did not affect phylochron and final leaf number. The accumulated thermal sum necessary to new leaf appearance depended upon each clone. New potato clones with high yield potential, for both crop conditions, can be identified through leaf number at tuber initiation under spring and autumn conditions. Season conditions have little effect on development of potato plants. The availability of solar radiation is the major atmosphere factor that explains yield variations between spring and autumn conditions in Rio Grande do Sul. |

Foram avaliados os clones SMIJ461-1, SMINIA793101-3, SMINIA97145-2 e a cultivar Macaca, nos cultivos de primavera e outono, em Santa Maria, RS. Foram determinados: número de folhas no início da tuberização e no final, filocrono, soma térmica acumulada da emergência ao início da tuberização e do início da tuberização ao início da senescência, e rendimento. As condições de temperatura e fotoperíodo modificaram os valores de soma térmica acumulada nas fases emergência–início da tuberização e início da tuberização–início da senescência, o rendimento e o número de folhas no início da tuberização, porém, não afetaram o filocrono e o número de folhas final. A soma térmica acumulada necessária ao aparecimento de folhas variou entre os clones. A determinação do número de folhas no início da tuberização, na primavera e no outono, pode ser utilizada para a identificação de clones com potencial de cultivo, em ambas as estações. O desenvolvimento das plantas de batata é pouco afetado pelas condições de cultivo. A disponibilidade de radiação solar determina as diferenças de rendimento dos cultivos de primavera e outono, no Rio Grande do Sul.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFAPERGS, CNPQBisognin, Dilson AntônioMüller, Douglas RenatoStreck, Nereu AugustoAndriolo, Jerônimo LuizSausen, Darlene2008-10-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/365Pesquisa Agropecuaria Brasileira; v.43, n.6, jun. 2008; 699-705Pesquisa Agropecuária Brasileira; v.43, n.6, jun. 2008; 699-7051678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/365/5446info:eu-repo/semantics/openAccess2014-07-02T17:42:22Zoai:ojs.seer.sct.embrapa.br:article/365Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-07-02T17:42:22Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
