Resumo: A limiting factor for wheat crop expansion or off-season crop in the Brazilian Cerrado is the occurrence of elevated temperatures during cropping cycle. This study aimed to evaluate the effects of temperature during the spikelet differentiation stage on biometric and productive parameters of wheat cultivars. A greenhouse experiment was carried out under a randomized blocks design, organized in a 2 x 4 factorial scheme, with four replicates. Two day/night thermo periods (16/9 ˚C and 25/16 ˚C) were applied in four wheat cultivars (BRS 394, BRS 331, BRS Parrudo and BRS Guamirim) during the spikelet differentiation stage. Yield components were determined for individual tillers and for the whole plant. Both thermo periods do not affect yield components of wheat, either morphological and productive uniformity of tillers, which show large variation among wheat cultivars.

O presente trabalho teve como objetivo avaliar o efeito da temperatura durante o estádio de diferenciação de espiguetas sobre parâmetros biométricos e componentes produtivos de cultivares de trigo. O experimento foi conduzido em cultivo protegido com delineamento experimental de blocos casualizados, em esquema fatorial 2 x 4, com quatro repetições. Dois regimes de temperatura diurna e noturna (16/9 ˚C e 25/16 ˚C) foram utilizados em quatro cultivares de trigo (BRS 394, BRS 331, BRS Parrudo e BRS Guamirim) durante o período de diferenciação das espiguetas. Os componentes de produção foram avaliados em perfilhos individuais e na planta inteira. Os regimes de temperatura testados não afetam os componentes de rendimento da cultura, tampouco a uniformidade morfológica e produtiva dos perfilhos, parâmetros que apresentaram grande variação entre as cultivares testadas.Universidade do Estado de Santa Catarina2019-02-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.udesc.br/index.php/agroveterinaria/article/view/1319610.5965/223811711812019024Revista de Ciências Agroveterinárias; Vol. 18 No. 1 (2019); 24-32Revista de Ciências Agroveterinárias; v. 18 n. 1 (2019); 24-322238-1171reponame:Revista de Ciências Agroveterinárias (Online)instname:Universidade do Estado de Santa Catarina (UDESC)instacron:UDESCporhttps://periodicos.udesc.br/index.php/agroveterinaria/article/view/13196/pdfCopyright (c) 2019 Revista de Ciências Agroveterinárias (Journal of Agroveterinary Sciences)info:eu-repo/semantics/openAccessFioreze, Samuel LuizVacari, JonathanTurek, Thais LemosMichelon, Luiz HenriqueDrun, Robson Pelissari2022-07-11T14:52:15Zoai::article/13196Revistahttps://periodicos.udesc.br/index.php/agroveterinaria/PUBhttps://periodicos.udesc.br/index.php/agroveterinaria/oairca.cav@udesc.br | portal.periodicos@udesc.brhttps://doi.org/10.5965/223811712238-11711676-9732opendoar:2022-07-11T14:52:15Revista de Ciências Agroveterinárias (Online) - Universidade do Estado de Santa Catarina (UDESC)false
