Resumo: | Mate (Ilex paraguariensis A. St.-Hil) is an arboreal species of great economic and socio-environmental importance, which presents difficulties in the adventitious rooting process. The rhizogenic competence of vegetative propagules of mate can be attained by coppicing, but the factors that influence the success of this technique have not yet been elucidated. Therefore, the aim of this study was to evaluate the effects of the stock plant, time of shoot collection, treatment with indolebutyric acid (IBA) and diameter of vegetative propagules in the adventitious rooting of cuttings from shoots induced by coppicing of selected adult plants of mate. Shoots produced from coppiced 13SM01 and 13SM05 stock plants were collected at different times of the year to prepare single-bud cuttings. The cuttings were measured as their diameter in the central portion and treated with 0 and 3000 mg L-1 of IBA. After 60 days, cuttings were evaluated to determine survival and rooting percentages, number of roots, and length of the three largest roots. A completely randomized design was used in a 4 × 2 × 2 × 13 (collection times x stock plants x IBA treatment x diameter classes) factorial scheme with 15 replications. Competence for adventitious rooting was highest for stock plant 13SM05. Cuttings collected in November and February had the highest rooting percentages, without the need of IBA treatment. Cuttings from 13SM01 and 13SM05 with diameters smaller than 0.636 cm (classes 1 to 6) and smaller than 0.712 cm (classes 1 to 7), respectively, had the highest rooting percentages and differed significantly from cuttings with larger diameters. Thus, the results of the present study indicate that stock plants, time of shoot collection, and diameter of vegetative propagules influence adventitious rooting competence of mate cuttings from coppicing adult plants. Rooting of mate cuttings with lower rhizogenic competence is influenced by the application of 3000 mg L-1 of IBA. |

St.-Hil) é uma espécie arbórea de grande importância econômica e socioambiental, que apresenta dificuldades no processo de enraizamento adventício. A competência rizogênica dos propágulos vegetativos de erva-mate pode ser obtida pelo decepa, mas os fatores que influenciam no sucesso dessa técnica ainda não foram elucidados. Assim sendo, o presente estudo objetivou avaliar a influência das características genéticas das plantas matrizes, das épocas de coleta, do tratamento com ácido indol-butírico (AIB) e do diâmetro de propágulos vegetativos no enraizamento adventício de estacas de brotações provenientes da decepa de plantas adultas selecionadas de erva-mate. Brotações produzidas a partir da decepa das plantas matrizes 13SM01 e 13SM05 foram coletadas em diferentes épocas e seccionadas em estacas de gema única. As estacas tiveram os diâmetros medidos na porção central e foram tratadas com 0 e 3000 mg L-1 de AIB. Aos 60 dias de cultivo, as estacas foram avaliadas quanto às porcentagens de sobrevivência e enraizamento, número de raízes e comprimento médio das três maiores raízes. O experimento foi um fatorial 4 × 2 × 2 × 13 (época de coleta x planta matriz x tratamento com AIB x classe de diâmetro das estacas) no delineamento inteiramente casualizado, com 15 repetições. A competência ao enraizamento adventício foi maior nas estacas coletadas da planta matriz 13SM05. As estacas coletadas em novembro e fevereiro apresentaram as maiores porcentagens de enraizamento, sem a necessidade de tratamento com AIB. Estacas oriundas de 13SM01 e 13SM05 com diâmetros menores que 0,636 cm (classes 1 a 6) e 0,712 cm (classes 1 a 7), respectivamente, apresentaram os maiores percentuais de enraizamento e diferiram significativamente das estacas com maiores diâmetros. Assim, os resultados do presente estudo indicam que as plantas matrizes, a época de coleta das brotações e o diâmetro dos propágulos vegetativos influenciam na competência ao enraizamento adventício de estacas de erva-mate oriundas da decepa de plantas adultas. O enraizamento de estacas com menor competência rizogênica é influenciado pela aplicação de 3000 mg L-1 de AIB.UEL2020-08-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Empírica de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3645410.5433/1679-0359.2020v41n5supl1p1849Semina: Ciências Agrárias; Vol. 41 No. 5supl1 (2020); 1849-1860Semina: Ciências Agrárias; v. 41 n. 5supl1 (2020); 1849-18601679-03591676-546Xreponame:Semina.
