“…Similar results were also observed in juvenile cuttings of some species. Rickli et al (2015), Ferriani et al (2011) andFerreira et al (2010), found high rooting percentages in the absence of the synthetic plant regulator for these species minicuts of Vochysia bifalcata, Sapium glandulatum and Piptocarpha angustifolia, respectively. The authors observed that as the concentration of IBA was increased, there was a slight decrease in the rooting rate, pointing this result to the high degree of youthfulness of the material, as the endogenous hormonal balance in these stakes favored rooting.…”

The propagation of S. amazonicum by seeds can result in uneven seedlings that are subject to poor quality, which is detrimental to uniformity and productivity. The absence of an efficient method of vegetative propagation of the species may be a limitation for genetic improvement, and consequently the increase in productivity of plantation. This study aimed to evaluate the effect of indole-3-butyric acid (IBA) in the rooting of cuttings of paricá -Schizolobium parahyba var. amazonicum (Huber ex Ducke) Barneby. The cuttings obtained from the stems of the seedlings then were treated with IBA in the hydro-alcoholic solutions at 1000, 2000, 3000 and 4000 ppm; commercial product with 2000 ppm IBA powder; commercial product composed of IBA and nutrients; and treatment control (0 ppm). The cuttings were planted in plastic trays with vermiculite and coconut fiber (1:1 v/v) and placed in a box lined with plastic to control moisture. The experimental design was completely randomized with five replications and 10 cuttings per plot. After 60 days, the percentage of rooted cuttings, living and dead, and number and length of roots were analyzed. The analysis of variance at 5% of probability indicated statistical differences for all variables. The best results were observed when we used IBA at 2000 and 3000 ppm, diluted in hydro-alcoholic solutions. These treatments showed statistically equal and produced the highest percentage of rooting, average number and length of roots and lowest percentage of dead cuttings. The polynomial regression analysis indicated that higher rooting rates can be obtained in 2550 ppm of IBA diluted in hydro-alcoholic solutions.Keywords: auxin, adventitious roots, fabaceae, vegetative propagation.

“…The coppicing and girdling techniques have been effective in breaking the relation between auxins and cytokinins, as used in practice to justify epicormic shoots induction in several tree species (SANTIN et al, 2008;DIAS et al, 2015;RICKLI et al, 2015). Among these, coppicing has shown greater effi cacy in terms of vegetative rescue in Ilex paraguariensis (WENDLING et al, 2013;STUEPP et al, 2015a;, Araucaria angustifolia (WENDLING et al, 2009), Anadenanthera macrocarpa (DIAS et al, 2015) and Toona ciliata (PEREIRA et al, 2015).…”

ABSTRAT:Calophyllum brasiliense is present in a wide natural distribution range in Brazil and its monopodial growth, with a rectilinear stem and a moderately dense timber has attracted the attention from the logging industry in recent decades. In the meantime, the lack of efficient rescue and vegetative propagation methods of adult plants has been a narrowing condition for the selection of superior genotypes in breeding programs of the species. Therefore, we evaluate epicormic shoots induction methods and the rooting cuttings of 14 year-old Calophyllum brasiliense trees. From this scope, three methods of epicormic shoots induction were evaluated: coppicing, girdling and partial girdling. We evaluate the number of produced sprouts and the percentage of sprouted trees at 06, 12 and 15 months' after the experiment installation. Results have indicated the feasibility of Calophyllum brasiliense vegetative rescue by cuttings method using epicormic shoots induced by coppicing and girdling. In contrast, partial girdling was not effective in epicormic shoots emission. Concerning adventitious roots, the sprouting technique had no influence in the rooting of cuttings, showing variation among the different stock plants. INDUÇÃO DE BROTAÇÕES EPICÓRMICAS E ESTAQUIA DE Calophyllum brasiliense RESUMO:Calophyllum brasiliense apresenta ampla distribuição natural no Brasil e seu crescimento monopodial, fuste retilíneo e madeira moderadamente densa tem atraído o interesse da indústria madeireira nas últimas décadas. Entretanto, a carência em métodos eficientes de resgate e propagação vegetativa de material adulto tem sido um fator limitante na seleção de genótipos superiores em programas de melhoramento da espécie. Assim, objetivou-se avaliar métodos de indução de brotações epicórmicas e o enraizamento de estacas em árvores de Calophyllum brasiliense com 14 anos de idade. Para tanto, três métodos de indução de brotações epicórmicas foram implantados: decepa, anelamento e semianelamento. Avaliou-se o número de brotos produzidos e a porcentagem de matrizes brotadas aos 6, 12 e 15 meses após a instalação do experimento. Com as brotações resultantes, foram instalados três experimentos de estaquia, comparando o enraizamento adventício entre as diferentes matrizes e métodos de indução de brotações epicórmicas. Os resultados demonstraram a viabilidade do resgate vegetativo de Calophyllum brasiliense por estaquia utilizando brotações epicórmicas induzidas por decepa e anelamento do tronco. Em contrapartida, o semianelamento não foi eficiente na indução de brotações epicórmicas. Em relação ao enraizamento adventício, a técnica de indução não influenciou o enraizamento de estacas, apresentando variação entre as diferentes matrizes.

“…In cutting technique, rejuvenated plants can be achieved with clear cutting or through a drastic pruning in mature trees for induction of epicormic shoots (STUEPP et al, 2014;RICKLI et al, 2015). However, the mini-cutting presents some advantages over cuttings, as size reduction of cuttings and increased shoots productivity per area, and youth use of propagules (DIAS et al, 2012).…”

“…Among the factors that influenced the content of endogenous auxin are the age (OSTERC & STAMPAR, 2011) and physiological conditions (WENDLING et al, 2014). Cuttings obtained from epicormic shoots, with more youthful and vigor material (RICKLI et al, 2015) in relation to the currentyear shoots, possibly possessed sufficient endogenous auxin that induced rooting. In this case, the addition of exogenous auxin generated a phytotoxic effect on the propagule, as has been observed for other species, and the concentration of IBA became harmful (NIENOW et al, 2010;FRAGOSO et al, 2015).…”

We aimed to evaluate the rooting potential of Tibouchina sellowiana through the experiments: I - Cuttings from current-year shoots and epicormic shoots were submitted to IBA concentrations: 0, 500, 1000, 1500 and 2000mg L-1, in a factorial arrangement 2 x 5 (two types of cuttings x five IBA concentrations), with four replicates and 20 cuttings each; II - mini-stumps of Tibouchina sellowiana were submitted to successive shoots collecting during the four seasons, in a split-plot design, with five replications of ten mini-stumps per experimental unit. From the shoots of mini-stumps, mini-cuttings were produced, which were initially kept in greenhouse and later transferred to full sun, in a 4 x 5 factorial arrangement (four seasons x five collections per season), with four replicates of 12 mini-cuttings. Superiority of epicormic shoots cuttings was reported when compared to the current-year shoots, which showed the highest rooting and leaves maintenance (42.50% and 55.00%, respectively), eliminating the use of IBA. High survival of mini-stumps (over 80%) and the mini-cuttings production (170mini-cuttings m-2 month-1) in clonal mini-garden and the mini-cuttings survival (above 80%) in the greenhouse demonstrated the technical feasibility, with summer as the most appropriate time to collect mini-cuttings.
