Resumo: | The species Bixa orellana L. is native to the Amazon and is in high demand due to the pharmacological properties of its fruits. However, research on germination and seedling production is incipient. The objective of this study was to evaluate the germination percentage with and without mechanical scarification of Bixa orellana L. seeds associated with commercial substrate or sand. The experiment was carried out in a completely randomized design, in a 2x2 factorial arrangement, with four treatments and four replications each. The germination rate and number of normal seedlings per treatment were determined. In addition to these parameters, the germination speed index, root and shoot length, and fresh and dry biomass of the seedlings were evaluated. The germination rate and normal and abnormal seedlings were expressed in percentage. In relation to the other parameters, the data were submitted to analysis of variance and the means were compared by the Scott-Knott test (p<0.01), with application of the Pearson correlation matrix (p<0.01) to the parameters. The germination rate showed higher values in sand (83%) and in commercial substrate (82%), and higher germination speed index when the seeds were scarified. The germination percentage was higher when sand was used and when the seeds were scarified. Thus, under nursery conditions, scarification was favorable to seed germination in both substrates. |

Porém, as pesquisas em relação a germinação e produção de mudas são incipientes. Objetivou-se avaliar a porcentagem de germinação com e sem escarificação mecânica de sementes de Bixa orellana L. associadas a substrato comercial ou areia. O ensaio foi conduzido em delineamento experimental inteiramente casualizado, em arranjo bifatorial 2x2, com quatro tratamentos e quatro repetições cada. Foram determinados a taxa de germinação e número de plântulas normais por tratamento. Além desses, foram avaliados o índice de velocidade de germinação, comprimento de raiz e de parte aérea, biomassa fresca e biomassa seca das mudas. A taxa de germinação e de plântulas normais e anormais foram expressos em porcentagem. Em relação aos demais parâmetros, os dados foram submetidos à análise de variância e as médias foram comparadas pelo teste de Scott-Knott (p<0,01), sendo aplicada a matriz de correlação de Pearson (p<0,01) aos parâmetros avaliados. A taxa de germinação apresentou valores superiores em areia (83%) e em substrato comercial (82%) e índice de velocidade de germinação superior quando as sementes foram escarificadas. Verificou-se que a porcentagem de germinação foi maior quando utilizada a areia e quando as sementes foram escarificadas. Dessa forma, em condições de viveiro a escarificação foi favorável à germinação das sementes em ambos os substratos.Universidade Federal Rural da Amazônia/UFRA2022-05-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionTextoinfo:eu-repo/semantics/otherapplication/pdfhttps://ajaes.ufra.edu.br/index.php/ajaes/article/view/3492Amazonian Journal of Agricultural Sciences Journal of Agricultural and Environmental Sciences; Vol 65 (2022): RCA AJAESRevista de Ciências Agrárias Amazonian Journal of Agricultural and Environmental Sciences; v. 65 (2022): RCA AJAES2177-87601517-591Xreponame:Revista de Ciências Agrárias (Belém.
