Resumo: In order to study the effects of gibberellic acid (GA3) on the growth of citrus rootstocks and the possibility of shortening the period of time for plant formation on nursery, four - month – old seedlings were sprayed with 0.50, 100, 150 and 200 ppm of GA3 solutions. Plant height increased significantly with the treatments which was positively correlated with GA3 level. The increases in plant height were 8, 37, 59 and 63%, respectively for 50, 100, 150 and 200 ppm. Stem girth was not affected by the different treatments. The higher concentrations (150 and 200 ppm) showed a tendency to promote dieback of the apex of the plants.

O AG3 nas doses mais elevadas aumentou significativamente a altura das plantas e houve correlação positiva com o nível da dose empregada. Verificou-se que as doses de 50, 100, 150 e 200 ppm promoveram aumentos da ordem de 8, 37, 59 e 63%, respectivamente. O diâmetro do caule não foi influenciado pelos distintos tratamentos. Nas doses maiores, 150 e 200 ppm, o crescimento excessivo das plantas tomou-as extremamente sensíveis, tendo-se verificado morte da parte apical de muitas plantas.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCoelho, Ygor da SilvaOliveira, Antonio Alberto RochaCaldas, Ranulfo Correa2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15466Pesquisa Agropecuaria Brasileira; v.18, n.11, nov. 1983; 1229 - 1232Pesquisa Agropecuária Brasileira; v.18, n.11, nov. 1983; 1229 - 12321678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15466/9398info:eu-repo/semantics/openAccess2014-04-16T18:43:23Zoai:ojs.seer.sct.embrapa.br:article/15466Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T18:43:23Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
