Resumo: The effect of temperature and leaf wetness duration on the development of Glomerella leaf spot disease was characterized in greenhouse study. Potted apple plants of cv. Gala were inoculated with C. gloeosporioides (106 conidia/ ml), and submitted to 12, 14, 16, 18, 20, 22, 24 and 26°C under continuous wetness (8, 10, 12, 18, 24, 30, 36, 42, 48, 54, 60,66, 72 and 96h). The best equation to explain the interaction between leaf wetness duration (LWD, h) and temperature (T,ºC) on the severity of Glomerella leaf spot was Y = -91,497 + (7,851 x T) + (0,243 x LWD) + (-0,177 x T x T) + (0,021 x T x LWD) + (-0,002 x LWD x LWD).

Potted apple plants of cv.

The best equation to explain the interaction between leaf wetness duration (LWD, h) and temperature (T,ºC) on the severity of Glomerella leaf spot was Y = -91,497 + (7,851 x T) + (0,243 x LWD) + (-0,177 x T x T) + (0,021 x T x LWD) + (-0,002 x LWD x LWD). Visando desenvolver um modelo de previsão da mancha da gala (Colletotrichum gloeosporioides), em casa de vegetação, em mudas de macieira com apenas uma haste, da cultivar Gala, foram inoculadas com suspensão de 1 x 106 conídios/ml de C. gloeosporioides e depois mantidas em câmara de inoculação a 12, 14, 16, 18, 20, 22, 24 e 26ºC (> 98% de umidade relativa do ar, no escuro) durante 8, 10, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72 e 96h. Foram, então, transferidas para uma sala de crescimento (14h de fotófase) nas mesmas temperaturas da inoculação. Pela interação entre o período de molhamento foliar e as diferentes temperaturas foi possível estabelecer uma superfície de resposta como modelo para estimar a severidade da mancha da gala, cuja equação resultante é: Y = -91,497 + (7,851 x T) + (0,243 x PMF) + (-0,177 x T x T) + (0,021 x T x PMF) + (-0,002 x PMF x PMF), onde T = temperatura (ºC) e PMF = período de molhamento foliar (h).Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina - Epagri2020-04-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://publicacoes.epagri.sc.gov.br/rac/article/view/748Agropecuária Catarinense Journal; Vol. 23 No. 3 (2010); 82-84Agropecuária Catarinense; v. 23 n. 3 (2010); 82-842525-60760103-0779reponame: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/748/646Copyright (c) 2020 Revista Agropecuária Catarinenseinfo:eu-repo/semantics/openAccessKatsurayama, YoshinoriBoneti, José Itamar da Silva2021-06-23T14:36:45Zoai:ojs.publicacoes.epagri.sc.gov.br:article/748Revistahttps://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:2021-06-23T14:36:45Agropecuária Catarinense (Online) - Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)false
