Resumo: This work was to analyze the duration and rate of tuberization, number of tubers, top weight and flowering through the developmental stages of the potato (Solanum tuberosum L., cv. Baronesa) at Pelotas, RS, Brazil. The plant was harvested at seven days intervals after emergence, through the cycle. Ortogonal polynomial analyzis of the fresh weight of the tubers and canopy in relation to time was employed to determine the best adjusted equation. The tuberization rate was obtained by the first derivative of the equation adjusted. The cultivar showed that the tuberization started at 23 days. The maximum tuberization was gotten at 83 days after emergence with 2,890.6 g/m2 and maximum rate was recorded at 36 with 64,4 g/m2 /day. The maximum of the canopy weight was reached at 49 days and decreased rapidly. The average number of tubers per plant showed linear function in relation to time, while the canopy weight presented a quadratic function. The tubers weight showed a cubic function. There was no correlation between canopy weight and/or number of the tubers. However, there was positive correlation between weight and number.

A análise de regressão curvilinear das médias dos tubérculos e da parte aérea em relação às coletas, com emprego de polinômios ortogonais, foi efetuada para determinar o melhor ajustamento aos dados. A velocidade de tuberização foi obtida pela derivada primeira da equação ajustada. A cultivar apresentou o início médio de tuberização aos 23 dias após a emergência. A tuberização máxima foi alcançada aos 83 dias após a emergência, com 2.890,6 g/m2 e a velocidade máxima, aos 36 dias após a emergência, com 64,4 g/m2/dia. Aos 49 dias o peso da parte aérea atingiu o máximo e, a partir daí, decresceu. O número de tubérculos por planta teve uma tendência linear em relação ao tempo, enquanto o peso da parte aérea apresentou uma tendência quadrática, entretanto, a curva do peso dos tubérculos mostrou uma tendência cúbica. Não houve correlação entre peso da parte aérea e peso e número de tubérculos, mas houve correlação positiva entre peso e número de tubérculos.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCosta, Delorge Mota daLopes, Nei Fernandes2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16414Pesquisa Agropecuaria Brasileira; v.17, n.12, dez. 1982; 1737-1741Pesquisa Agropecuária Brasileira; v.17, n.12, dez. 1982; 1737-17411678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16414/10665info:eu-repo/semantics/openAccess2014-04-16T11:50:18Zoai:ojs.seer.sct.embrapa.br:article/16414Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T11:50:18Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
