Resumo: | The objective of the present work was to study the effect of plant growth regulators on cassava productivity (Manihot esculenta Crantz cv Branca de Santa Catarina). The experiment was carried out on the Fazenda Experimental São Manuel, Faculdade de Ciências Agronômicas, Campus de Botucatu, UNESP. The soil was prepared as usual, and cassava stem segments were treated with PGR and copper sulfate 20 g/l, planted with density 1,0 x 0,5. The treatments were: 1) IBA 100 mg.L-1; 2) 2,4-D 50 mg.L-1; 3) GA3 50 mg.L-1; 4( Kinetin 50 mg.L-1; 5) SADH 50 mg.L.-1; 6) CEPA 50 mg.L-1; 7) CCC 50 ml/l; 8) Water. The dry-weight percentage, amido percentage, soluble carbohydrate content (mg/g od dry-matter - DM), nitrogen content (% DM), ohosphorus content (% DM), potassium content (% DM), calcium content (% DM), magnesium content (% DM), sulfur content (% DM), boron content (ppm), copper content (ppm), iron content (ppm), Mn content (ppm) and zinc content (ppm) were measured. The plant-growth regulator application, under the conditions of the experiment, did not increase the quality of Manihot esculenta. Application of 2,4-D resulted in higher accumulation of phosphorus and magnesium, and application of CCC increased dry-matter percentage and amido percentage. |

As manivas foram plantadas após tratamento com fitorreguladores e sulfato de cobre 20 g/l, com espaçamento de 1,0 x 0,5 m. Os tratamentos empregados foram: 1) Ácido indol-butírico (AIB) 100 mg.L-1; 2) Ácido 2,4-Diclorofenoxiacético (2,4-D) 50 mg.L-1; 3) Ácido giberélico (GA3) 50 mg.L-1; 4) Furfurilaminopurina 50 mg.L-1; 5) Ácido succínico-2, 2-dimetilhidrazina (SADH) 50 mg.L-1; 6) Ácido (2-cloroetil) fosfônico (CEPA) 50 mg.L-1; 7) Cloreto de 2-cloroetil-trimetilamônio (CCC) 50 ml/l; 8) Testemunha. Observaram-se os seguintes parâmetros nas raízes tuberosas formadas; % de peso seco; % de amido; teor de carboidratos solúveis (mg/g de matéria seca - MS); teor de nitrogênio, fosforo, potássio, cálcio, magnésio e enxofre (em % MS); teor de boro, cobre, ferro, manganês e zinco (em ppm). A aplicação de fitorreguladores, nas condições do experimento, não levou a uma melhoria na qualidade da mandioca. A aplicação de 2,4-D levou ao maior acúmulo de fósforo e magnésio nas raízes e a aplicação de CCC a maior porcentagem de peso seco e amido.Universidade Federal de Santa Catarina1998-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/21928Biotemas; v. 11 n. 1 (1998); 17-312175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/biotemas/article/view/21928/19889Copyright (c) 1998 Selma Dzimidas Rodrigues, João Domingos Rodrigues, Elizabeth Orika Ono, José Figueiredo Pedrashttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessRodrigues, Selma DzimidasRodrigues, João DomingosOno, Elizabeth OrikaPedras, José Figueiredo2022-11-18T13:09:57Zoai:periodicos.ufsc.br:article/21928Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2022-11-18T13:09:57Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false |
