Resumo: The influence of water on growth and development of fruits of bean plants Phaseolus vulgaris L. cv, Goiano Precoce was studied. The effect of water availability on the pre-flowering,flowering and fruiting stages received special attention. Plants under a twice a week irrigation regime showed the most rapid vegetative (relative growth rate = 0.1910 g/g/day and net assimilation rate = 0.243 mg/cm2/ day). Abscission of flower buds was associated with changes in water stress: 31.7%, 7.2% and 0% in stressed plants that had been under irrigation every day, once a week and twice a week, respectively. Flowers and fruit set ware also strongly affected by water availability; under water stress a higher percentage of abscission was observed in all the irrigation regimes studied (36% - 50%).

Goiano Precoce. A influência da disponibilidade de água nas fases de prefloração, floração e frutificação foi especialmente observada. As plantas que receberam irrigação duas vezes por semana apresentaram melhor desenvolvimento vegetativo, ou seja, da ordem de 0,1910 g/g/dia e em torno de 0,243 mg/cm2/dia, com base no peso seco. A perda de botões florais provocada pelo estresse hídrico foi da ordem de 31,7% em plantas irrigadas diariamente; de 7,2% em plantas irrigadas uma vez por semana; em plantas irrigadas duas vezes por semana, 0%. Tanto as flores como os frutos foram fortemente afetados pela disponibilidade de água. Dentre todos os tratamentos estudados, observou-se, nos tratamentos sob estresse hídrico, maior percentual de perda (36 - 50%).Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraHostalâcio, SarasvateVálio, Ivany F.M.2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15386Pesquisa Agropecuaria Brasileira; v.19, n.2, fev. 1984; 211-218Pesquisa Agropecuária Brasileira; v.19, n.2, fev. 1984; 211-2181678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15386/9274info:eu-repo/semantics/openAccess2014-04-16T19:16:05Zoai:ojs.seer.sct.embrapa.br:article/15386Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T19:16:05Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
