“…This could explain the increase in rooting percentage, number of roots and length of the three largest roots when 3000 mg L -1 of IBA was applied. These results are in agreement with those obtained from Langerstroemia indica L. cuttings, for which the number of roots increased by up to 47 % when treated with 3000 mg L -1 of IBA (D. M. L. Lima, Klein, Salla, Moura, & Danner, 2016). The application of 3000 mg L -1 of IBA also promoted adventitious rooting of cuttings collected from different positions in the same stock plants used in the present study (Bisognin et al, 2018).…”

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.

“…Além das características adequadas apresentadas pelos substratos, é importante salientar que o desenvolvimento de brotações em estacas também sofre variações entre as diferentes concentrações de ácido indolbutírico, podendo o maior crescimento de brotações estar relacionado, também, com o enraizamento (LIMA et al, 2016). Neste sentido, temse que pontos de crescimento radicular em formação constituem locais de síntese de citocininas, que são translocadas aos pontos de crescimento na parte área, estimulando a multiplicação celular (TAIZ; ZEIGER, 2013).…”

Presente em todas as regiões, a mandioca, tem importância fundamental na alimentação humana e animal, seja como matéria-prima para a obtenção de produtos industriais e/ou na geração de emprego e renda no campo. Em meio à relevância desta cultura para o atual cenário econômico nacional, objetivou-se com este estudo avaliar os efeitos de diferentes composições de substratos sobre o desenvolvimento de estruturas vegetativas de mandioca do tipo mesa mediante a adaptação da técnica de propagação rápida, como alternativa à oferta de mudas de melhor qualidade para comunidades tradicionais inseridas no semiárido piauiense. O experimento foi desenvolvido em ambiente protegido no Instituto Federal do Piauí, Campus Oeiras. Obedecendo ao delineamento em blocos casualizados, sendo testadas 12 composições de substratos formulados a partir da mistura de areia lavada, solo e esterco bovino. A mistura de substratos Solo + Areia lavada + Esterco bovino (1:1:2) e Areia lavada + Esterco bovino (1:2) são eficientes para o desenvolvimento vegetativo das brotações de mandioca do tipo mesa, permitem a obtenção de mudas de melhor qualidade para estabelecimento em campo e, portanto, são recomendados para produção de mudas da cultura no processo de propagação rápida.

“…A oxidação do AIA pode ocorrer por um processo de foto-oxidação e através de reações de oxidação catalisadas por enzimas (AIA-oxidase). Quando a concentração de auxina no meio é excessiva, ocorre formação de calo na base para que posteriormente inicie a formação das raízes adventícias (LIMA et al, 2016;SOUZA et al, 2018).…”

The serigueleira is a fruit that is little explored commercially in several regions of Brazil, having little work regarding the feasibility of seedling production by cuttings with and without plant regulators. Due to this lack of technical information, the present work has as main objective to evaluate the rooting of herbaceous and woody cuttings of the serigueleira (Spondias purpurea L.) treated with indolbutyric acid (AIB). Herbaceous and woody cuttings were obtained from a matrix plant with approximately fifteen years of age, with 12 cm in length the cuttings were cut in bevel and then immersed in a commercial fungicide solution of 0.2%. The cuttings were treated with AIB in the form of talc, 0, 1%, 2%, 3% and 5%, planted in beds containing vermiculite, rice straw and construction sand. The experimental design used was completely randomized, with four replications, each plot consisting of 10 cuttings. Cuttings were evaluated over 90 days, recording the following parameters: percentage of rooted cuttings, percentage of live cuttings and calluses, number of cuttings with buds, average length of the largest root and number of roots. Among the results obtained, the best concentration was 3% of 5% IBA in the rooting of herbaceous cuttings (17,25% in 17,75%) and 5% of IBA in the rooting of woody cuttings (22,25% e 22,55%). Herbaceous cuttings showed higher percentages of cuttings with calluses when compared to woody cuttings.
