Resumo: Brazil imports almost all pear fruits necessary to supply it's need. The insufficient local pear production is due to the lack of climatic adaptation of the currently planted cultivars. Most of them are from colder climates compared to that of Southern Brazil. It is supposed that the lack of chilling hours and the daily temperature fluctuation during the winter are the main factors involved on biochemical and physiological process changes. This results inreduction of floral buds/tree, low number of flowers/floral bud, necrosis and even drop of buds. These symptoms are known as ‘bud abortion' or ‘bud necrosis'. This paper discusses this subject and suggests to carry out more research and to breed new high fruit quality pear cultivars that have lower chilling requirement and tolerance to dailytemperature fluctuations, very common in Southern of Brazil.

O Brasil praticamente importa a totalidade da pêra consumida in natura devido à falta de cultivares adaptadas às suas condições edafoclimáticas. Isso se deve ao fato de a pereira ser originária de regiões muito frias e as cultivares de alta qualidade terem sido selecionadas para essas condições. Acredita-se que a pouca quantidade de frio hibernal e a alternância diária da temperatura no inverno, existentes no Sul do Brasil, são os principais fatores que induzem as pereiras a alterar os processos bioquímicos/fisiológicos, resultando em menor quantidade de gemas florais/planta, baixo número de flores/gema, necrose e até queda da gema, sintomas designados como "abortamento" ou "necrose" de gemas. Este artigo comenta esse assunto e sugere a realização de pesquisas e a obtenção de cultivaresde alta qualidade comercial, com menor exigência em frio hibernal e tolerantes às alterações climáticas diárias.Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina - Epagri2004-07-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://publicacoes.epagri.sc.gov.br/rac/article/view/1000Agropecuária Catarinense Journal; Vol. 17 No. 2 (2004); 54-57Agropecuária Catarinense; v. 17 n. 2 (2004); 54-572525-60760103-0779reponame: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/1000/897Copyright (c) 2004 Agropecuaria catarinensehttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessFaoro, Ivan dagberto2021-07-28T17:17:00Zoai:ojs.publicacoes.epagri.sc.gov.br:article/1000Revistahttps://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:2021-07-28T17:17Agropecuária Catarinense (Online) - Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)false
