Resumo: | This work aimed to evaluate the rooting of guarana genotypes immersed in IBA, 2,4-D and NAA rooting solutions. The experiment was carried out in Experimental Farm of Embrapa Western Amazon, in a randomized block design, with a factorial arrangement of 16 genotypes x three growth regulators + 01 additional controls, with 2 replicates and 10 plants per plot. Percentage of rooted cuttings, cuttings with callus and dead cuttings, the number of roots, length of the longest root (cm), root volume (mL), fresh weight of roots (g) and root dry mass (g) were assessed after 90 days. IBA and NAA treatment improved the quality of the root system of cuttings from all guarana genotypes. The highest mortality was observed in the treatment with 2,4-D. All other characteristics were influenced by the different rooting solutions, except the percentage of cuttings with callus. The genotypes showed great variability regarding rooting, especially the CMU 1004, CMU 1005, CMU 1006 and CMU 1014 with the highest percentages of rooted cuttings, while CMU 1016 and CMU 1022 showed the lowest rooting rates. There was a significant interaction between genotypes x rooting solutions for volume, fresh weight and dry weight of roots. However, the factorial versus control contrast was not significant; thus, the use of rooting solutions does not influence the rooting of guarana cuttings. |

O experimento foi conduzido no Campo Experimental da Embrapa Amazônia Ocidental em Manaus, no delineamento de blocos ao acaso em arranjo fatorial com 16 genótipos x três reguladores de crescimento + 01 testemunha adicional, com 2 repetições e 10 plantas por parcela. Após 90 dias, foi avaliada a porcentagem de estacas enraizadas, estacas com calos e estacas mortas, número de raízes, comprimento da maior raiz (cm), volume de raízes (mL), massa fresca de raízes (g) e massa seca de raízes (g). Os tratamentos com AIB e ANA melhoraram a qualidade do sistema radicular das estacas. A maior mortalidade foi observada nas estacas com 2,4-D. Todas as outras caraterísticas foram influenciadas pelas soluções enraizadoras, exceto a porcentagem de estacas com calos. Os genótipos apresentaram grande variabilidade quanto ao enraizamento, destacando-se os genótipos CMU 1004, CMU 1005, CMU 1006 e CMU 1014 com maiores porcentagens de estacas enraizadas, enquanto os genótipos CMU 1016 e CMU 1022 apresentaram as menores taxas de enraizamento. Houve interação significativa entre genótipos x soluções enraizadoras para volume, peso fresco e peso seco de raízes. O contraste fatorial versus controle foi não significativo, assim, o uso de soluções enraizadoras não influencia no enraizamento de estacas de guaranazeiro.Universidade Federal Rural da Amazônia/UFRA2023-12-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontextoapplication/pdfhttps://ajaes.ufra.edu.br/index.php/ajaes/article/view/3513Amazonian Journal of Agricultural Sciences Journal of Agricultural and Environmental Sciences; Vol 66 (2023): RCA AJAES; 1-19Revista de Ciências Agrárias Amazonian Journal of Agricultural and Environmental Sciences; v. 66 (2023): RCA AJAES; 1-192177-87601517-591Xreponame:Revista de Ciências Agrárias (Belém.

There was a significant interaction between genotypes x rooting solutions for volume, fresh weight and dry weight of roots. However, the factorial versus control contrast was not significant; thus, the use of rooting solutions does not influence the rooting of guarana cuttings. |
