Abstract -      The objective of this work was to evaluate the rooting of herbaceous cuttings of CAMB-06 and APU-04 acerola cherry selections associated with the use of indolebutyric acid (IBA) and a concentration of aqueous extract of coco-grass. Cuttings were treated by immersion with different concentrations of IBA (0; 1,000; 2,000; 3,000; 4,000 mg L-1) and one application of aqueous extract of coco-grass in proportion 100% and placed to root in plastic boxes containing vermiculite. The experimental design was a completely randomized in a 2×6 factorial arrangement (two acerola cherry selections and six solutions for rooting) with four replicates of ten cuttings. After 90 days of cutting, the following variables were evaluated: cutting survival (%); leaf retention (%); rooted cuttings (%); sprouting (%); number of roots per cutting (%); length of roots (cm) and dry mass of roots per cutting (g). It was concluded that the application of IBA at 4,000 mg L-1 presented a better root development, resulting in a higher percentage of rooted cuttings and higher number and dry mass of roots in relation to IBA at 0 mg L-1 for CAMB-06 selection, while the APU-04 selection can be efficiently multiplied by herbaceous cuttings without the use of IBA. Under the conditions that the trials was conducted, the application of 100% aqueous extract of coco-grass was not effective in promoting the rooting of cuttings of CAMB-06 and APU-04 acerola cherry selections.

Resumo –      O objetivo deste trabalho foi avaliar o enraizamento de estacas herbáceas das seleções de acerolas CAMB-06 e APU-04 associadas ao uso de ácido indolbutírico (AIB) e uma concentração de extrato aquoso de tiririca. As estacas foram tratadas por imersão com diferentes concentrações de AIB (0; 1.000; 2.000; 3.000 e 4.000 mg L-1) e uma aplicação de extrato aquoso de tiririca, na proporção 100%, e dispostas para enraizar em caixas plásticas contendo vermiculita. O delineamento experimental foi inteiramente casualizado, em arranjo fatorial 2×6 (duas seleções e seis soluções para enraizamento) com quatro repetições de dez estacas. Após 90 dias da estaquia, foram avaliadas: sobrevivência das estacas (%); retenção foliar (%); estacas enraizadas (%); brotação (%); número de raízes por estaca (%); comprimento de raízes (cm) e massa seca de raízes por estaca (g). Concluiu-se que a aplicação de AIB na concentração 4.000 mg L-1 apresentou melhor desenvolvimento radicial, resultando em maior porcentagem de estacas enraizadas e maior número e massa seca de raízes em relação à concentração 0 mg L-1 de AIB para a seleção CAMB-06, enquanto a seleção APU-04 pode ser propagada por estaquia herbácea com eficiência, sem o uso de AIB. Nas condições em que o experimento foi conduzido, a aplicação de 100% de extrato aquoso de tiririca não foi efetiva na promoção do enraizamento de estacas das seleções de acerola CAMB-06 e APU-04.
