Resumo: | Buds of lAN 717 rubber tree clone were treated with a solution of colchicine plus dimethyl sulfoxide (DMSO) to induce polyploidy in plants with 2n = 36 chromosomes. Sprouts from five treated buds showed morphological variation and were vegetatively multiplied as clones. Mitotic studies of the leaf tip confirmed a high degree of mixoploidy. Morphologically, the polyploidy clones differed from the control diploid in having shorter height, greater stem diameter, smaller L/B ratio of the stomata, larger petiole and larger stomata. Quantitative characters of the polyploid clones with respect to cytology, bark characters, foliage characters, stomata parameters and yield by the Mendes early test are presented. In addition, a study of the occurrence of correlation between yield and various yield determining factors of the bark was carried out. More studies on the new polyploidy clones are recommended. |

Brotações de cinco gemas tratadas apresentaram variações morfológicas e foram multiplicadas assexuadamente como novos clones. Estudos mitóticos do ápice foliar confirmaram um alto grau de mixoploidia. Morfologicamente, os clones poliplóides diferiram dos clones diplóides-testemunha em menor altura, maior diâmetro da haste, menor, relação do comprimento e largura do estômato, maior pecíolo e maior estômato. Caracteres quantitativos dos clones poliplóides, no que diz respeito à citologia, casca, folha, estômato e produção pelo teste de Mendes, são apresentados no trabalho. Foi verificada a possível ocorrência de correlações entre produção e os parâmetros determinantes da produção da casca. Recomenda-se fazer estudos adicionais referentes aos novos poliplóides obtidos.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraGonçalves, Paulo de SouzaValois, Afonso Celso C.Paiva, João Rodrigues de2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15368Pesquisa Agropecuaria Brasileira; v.18, n.7, jul. 1983; 789-796Pesquisa Agropecuária Brasileira; v.18, n.7, jul. 1983; 789-7961678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/15368/9240info:eu-repo/semantics/openAccess2014-04-16T18:59:42Zoai:ojs.seer.sct.embrapa.br:article/15368Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T18:59:42Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
