Resumo: | The objective of this work was to evaluate the fruiting and vegetative growth of 'Starkrimson' pear in response to the application of prohexadione calcium (P-Ca). P-Ca (250 mg L-1) was sprayed to scaffold limbs and to whole trees in commercial orchards. A randomized complete block design was used to minimize declivity effects. Vegetative growth (length and number of shoots, increment in limb and trunk cross-sectional area, number of nodes, and internode length), production (fruit number, yield, yield efficiency, and fruit size), and return bloom were evaluated from 2010 to 2013. P-Ca efficiently controlled shoot growth in all growing seasons, when applied early in the season, due to the reduction in internode length. Production was not negatively affected by the application of P-Ca in all years and at both sites, and fruit size and return bloom were not reduced. Fruit quality attributes were also little affected by P-Ca, except for total soluble solids content, which was lower than that of the control. This shows that P-Ca is efficient to manage tree vigor in high-density 'Starkrimson' pear orchards. |

Aplicou-se P-Ca (250 mg L-1) em ramificações laterais e em plantas inteiras, em pomares comerciais. Utilizou-se o delineamento experimental de blocos ao acaso, para minimizar os efeitos da declividade do terreno. O crescimento vegetativo (comprimento e número de ramos, incremento da área da secção transversal dos ramos laterais e do tronco, número de nós e comprimento de entrenós), a produção (número de frutos, produtividade, eficiência produtiva e tamanho de fruto) e o retorno da floração foram avaliados de 2010 a 2013. P-Ca foi eficiente no controle do crescimento de ramos em todas as safras, quando aplicada no início do ciclo de crescimento, devido à redução no comprimento dos entrenós. A produção não foi afetada negativamente pela aplicação de P-Ca em todos os anos e em ambos os locais, e o tamanho de fruto e o retorno da floração não foram reduzidos. Os atributos de qualidade dos frutos também foram pouco afetados por P-Ca, exceto o teor de sólidos solúveis totais, que foi menor que o do controle. Assim, P-Ca é eficiente no manejo do vigor em pomares de alta densidade de peras 'Starkrimson'.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraPasa, Mateus da SilveiraEinhorn, Todd2017-03-24info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/23172Pesquisa Agropecuaria Brasileira; v.52, n.2, fev. 2017; 75-83Pesquisa Agropecuária Brasileira; v.52, n.2, fev. 2017; 75-831678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/23172/13709https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/23172/15165https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/23172/15166https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/23172/15167Direitos autorais 2017 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2017-03-24T19:50:52Zoai:ojs.seer.sct.embrapa.br:article/23172Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2017-03-24T19:50:52Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
