Resumo: | The objective of this research was to evaluate the effect of the caryopsis classification, the acid scarification and the treatment with potassium nitrate in the seed germination of a Paspalum notatum Flügge ecotype from the Guarapuava region, Paraná State. The experimental design was the completely randomized in a factorial arrangement with three factors: caryopsis classes (three classes gotten in a seed blower in openings four, five and six), sulfuric acid concentrated treatment period (0, 7.5 and 15 minutes) and potassium nitrate concentration (0 and 0.2 %). The seed germination was evaluated after 7, 14, 21 and 28 days. The germination percentage, the germination speed index and the average time to germination were evaluated. The best germination obtained was 12.2% for the seeds of class six scarified for 15 minutes. Seeds from class four and not treated with sulfuric acid did not germinate. There was no interference of potassium nitrate treatment on seed germination. The classification and the acid scarification of the caryopsis were favorable to increase P. notatum seed germination. |

Adotou-se o delineamento experimental completamente casualizado em arranjo fatorial com três fatores: classe das cariopses (três classes obtidas em soprador de sementes nas aberturas quatro, cinco e seis), tempo de tratamento com ácido sulfúrico concentrado (0, 7,5 e 15 minutos) e concentração de nitrato de potássio (0 e 0,2%). Foram avaliados a germinação após 7, 14, 21 e 28 dias, o índice de velocidade de germinação e o tempo médio para germinação. A maior germinação obtida foi de 12,2% para as sementes da classe seis do soprador e escarificadas por 15 minutos. Não ocorreu germinação das sementes da classe quatro que não receberam escarificação ácida e não houve interferência do nitrato de potássio. Concluiu-se que a classificação e a escarificação ácida das cariopses favoreceram a germinação das sementes de P. notatum.UEL2009-12-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/465510.5433/1679-0359.2009v30n4Sup1p1187Semina: Ciências Agrárias; Vol. 30 No. 4Sup1 (2009); 1187-1194Semina: Ciências Agrárias; v. 30 n. 4Sup1 (2009); 1187-11941679-03591676-546Xreponame:Semina.
