Resumo: Abstract - Burrknots are aerial root nodules that obstruct the vascularization of apple plants, which can cause depletion of the fruit tree. Usually, the evaluation of the occurrence of this disorder is restricted to the rootstock region. The objective of the study was to develop a scale for the evaluation of the occurrence of burrknots in the apple trees, and to present a practical application of the developed scale. Plants with different intensities of burrknots along the stem and branches were observed, which were classified into five phenotypically distinct groups for this disorder (scale 1 to 5). In the practical application of the scale, 12 segregating populations of apple trees were phenotypically evaluated, which allowed to characterize the individual and average behavior of the progenies, and to identify the parents with greater potential of transmitting this character to their hybrids. The suggested scale was efficient in the evaluation of the occurrence of burrknots in apple trees, demonstrating their applicability in studies with different purposes.

Comumente a avaliação da ocorrência desse distúrbio se restringe à região do porta-enxerto. O objetvo do trabalho foi desenvolver uma escala de avaliação da ocorrência de burrknots em plantas copa de macieira, e apresentar uma aplicação prátca da escala desenvolvida. Foram observadas plantas com diferentes intensidades de burrknots ao longo do caule e dos ramos, sendo classifcadas em cinco grupos distntos fenotpicamente (escala de 1 a 5). Na aplicação prátca da escala foram avaliadas fenotpicamente 12 populações segregantes de macieira que permitram caracterizar o comportamento individual e médio das progênies e identfcar os genitores com maior potencial de transmitr esse caráter aos seus híbridos. A escala sugerida foi efciente na avaliação da ocorrência deburrknots em macieira, demonstrando a sua aplicabilidade em estudos com diferentes fnalidades.  Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina - Epagri2018-06-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://publicacoes.epagri.sc.gov.br/rac/article/view/262Agropecuária Catarinense Journal; Vol. 31 No. 2 (2018); 63-67Agropecuária Catarinense; v. 31 n. 2 (2018); 63-672525-60760103-0779reponame:Agropecuária Catarinense (Online)instname:Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)instacron:EPAGRIporhttps://publicacoes.epagri.sc.gov.br/rac/article/view/262/230Copyright (c) 2018 Revista Agropecuária Catarinensehttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessBrancher, Thyana LaysCrestani Hawerroth, MaraisaKvitschal, Marcus ViníciusHawerroth, Fernando JoséCouto, Marcelo2018-07-18T17:45:12Zoai:ojs.publicacoes.epagri.sc.gov.br:article/262Revistahttps://publicacoes.epagri.sc.gov.br/RAC/indexPUBhttps://publicacoes.epagri.sc.gov.br/index.php/RAC/oaieditoriarac@epagri.sc.gov.br || lamperuch@epagri.sc.gov.br2525-60760103-0779opendoar:2018-07-18T17:45:12Agropecuária Catarinense (Online) - Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)false
