Resumo: The aim of this study was to evaluate physiological quality in seeds of sweet sorghum grown under semi-arid conditions, and to determine the age of physiological maturity of the seeds as a function of the foliar application of potassium silicate. The experiment was carried out at the Curu Valley Experimental Farm, in Pentecoste in the state of Ceará, during the rainy seasons of 2014 and 2015. The BRS 506 and BRS 511 varieties were used, under foliar fertilisation with potassium silicate at doses of 500, 1000 and 1500 mL.ha-1, in addition to the control lots (with no application); harvesting was at four periods, 30, 37, 44 and 51 days after full bloom (DAB). The percentage and speed of germination were evaluated, together with the accelerated ageing test and seedling growth. The seeds presented greater than 90% germination from 37 DAB, reaching high seedling vigour at 51 DAB. Foliar fertilisation with potassium silicate under the conditions of the experiment resulted in an increase in the physiological quality of the seeds. The BRS 506 and BRS 511 cultivars displayed the highest physiological quality between 49 and 53 DAF.

O experimento foi conduzido na Fazenda Experimental Vale do Curu, Pentecoste – CE no período de chuvas dos anos de 2014 e 2015. Utilizaram-se as variedades BRS 506 e BRS 511 sob adubação foliar com silicato de potássio nas doses 500; 1000 e 1500 mL.ha-1, além das parcelas controle (sem aplicação) e com colheita realizada em quatro épocas (30, 37, 44 e 51 dias após a plena floração (DAF)). Foram avaliados as porcentagens e velocidade de germinação, o teste de envelhecimento acelerado e o crescimento de plântulas. As sementes obtiveram germinação acima de 90% a partir dos 37 dias DAF, atingindo alto vigor de plântulas aos 51 dias APF. A adubação foliar com silicato de potássio nas condições aplicadas promoveu acréscimo na qualidade fisiológica das sementes. As cultivares BRS 506 e BRS 511 apresentam o máximo de qualidade fisiológica entre 49 e 53 dias DAF.Universidade Federal Rural do Semi-Árido2017-03-21info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/641610.1590/1983-21252017v30n320rcREVISTA CAATINGA; Vol. 30 No. 3 (2017); 718-729Revista Caatinga; v. 30 n. 3 (2017); 718-7291983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/6416/pdfCopyright (c) 2017 Revista Caatingainfo:eu-repo/semantics/openAccessLessa, Bruno França da TrindadeDutra, Alek SandroSilva, Tatiana Maria daSantos, Camila CastroSousa, Wesley do Nascimento2023-07-20T11:18:01Zoai:ojs.periodicos.ufersa.edu.br:article/6416Revistahttps://periodicos.ufersa.edu.br/index.php/caatinga/indexPUBhttps://periodicos.ufersa.edu.br/index.php/caatinga/oaipatricio@ufersa.edu.br|| caatinga@ufersa.edu.br1983-21250100-316Xopendoar:2024-04-29T09:46:28.171392Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true
