“…Os autores ainda relatam que diversas espécies da família Myrtaceae apresentam dificuldades de enraizamento, tais como jabuticabeiras e goiabeiras. No entanto, a literatura apresenta eficientes resultados de enraizamento de estacas de espécies desta família com o uso de reguladores vegetais, em especial com aplicação de AIB (COSTA JUNIOR; SCARPARE FILHO; BASTOS, 2003;DELgADO;YUYAMA, 2010).

ResumoA Melaleuca alternifolia é uma árvore da família Myrtaceae, de grande importância medicinal. Seu óleo essencial é muito utilizado tanto na medicina humana quanto na medicina veterinária, tendo grande poder antiséptico. É uma planta de difícil enraizamento no processo de estaquia. Assim, o presente trabalho teve como objetivo avaliar a eficiência de diferentes concentrações de ANA e AIB, no enraizamento de estacas de M. alternifolia. Foram utilizadas estacas com 10 cm de comprimento, submetidas ao tratamento para enraizamento com dois reguladores vegetais ANA e AIB, nas seguintes concentrações: 0 (testemunha); 1000; 2000 e 4000 mg L -1 . Aos 97 dias foram avaliados a porcentagem de estacas enraizadas, vivas e mortas, o comprimento, o volume e a massa seca de raízes. O regulador vegetal ANA na concentração de 4000 mg L -1 demonstrou ser fitotóxico para as estacas de melaleuca e o uso de AIB em relação ao ANA, na concentração de 4000 mg L -1 , proporcionou maior porcentagem de estacas enraizadas e maior comprimento radicial. Palavras-chave: Myrtaceae, estaquia, AIB; ANA AbstractThe Melaleuca alternifolia is a Myrtaceae tree of great medicinal importance. Its essential oil is widely used both in human and in veterinary medicine, having great antiseptic power. It is a difficult plant in the process of rooting cuttings. This study aimed to evaluate the efficacy of different concentrations of NAA and IBA on the rooting of M. alternifolia. Melaleuca cuttings with 10 cm in length were submitted to treatments with two regulators, NAA and IBA, in the following concentrations: 0 (control), 1000, 2000 and 4000 mg L -1 . Evaluation occurred at 97 days throughout the live and dead cuttings rooted, medium length, volume and mass of roots. The growth regulator NAA at a concentration of 4000 mg L -1 showed to be phytotoxic to the cuttings of melaleuca; the use of IBA in comparable with NAA at concentration of 4000 mg L -1 provided a higher percentage of rooting and root length increases.

“…However, other species from the family Myrtaceae have shown a positive effect related to the application of IBA. For example, cuttings from camu camu trees (Myrciaria dubia) have shown 58% rooting at 200 mg L -1 (Delgado & Yuyama, 2010) and the highest rooting rate (41%) in cuttings from Blepharocalyx cruckshanksii was observed at 2,000 mg L -1 (Vidal et al, 2010).…”

Campomanesia aurea is a potentially ornamental native species of the Pampa Biome and its vegetative propagation may be an alternative for producing seedlings on a commercial scale. Thus, the goal of this study was to verify the feasibility of vegetative propagation of C. aurea collected at different times under the use of IBA. Cuttings were collected in an in situ in the Municipality of Barão do Triunfo, RS, Brazil, in autumn, winter and spring. IBA at concentrations of zero, 2,000, 4,000, 6,000 and 8,000 mg L-1 were tested. Rooting, callogenesis, leaf retention, mortality and root dry matter were analyzed. There was interaction between the doses of IBA and the collection time of cuttings in relation to rooting. In autumn, there was quadratic behavior with a maximum of 28% rooting with curve inflection at IBA doses above 6,500 mg L-1. The highest callogenesis and leaf retention rates and the lowest mortality rate have been observed in autumn. However, the highest rooting rate and the best root system quality have been observed in spring. We have therefore concluded that the vegetative propagation of C. aurea is feasible and the effects of IBA are dependent on the collection time of propagules.

“…At 116 days from planting, no statistically significant difference was observed for cutting sprouting (maximum 60%). In a study with Myrciaria dubia stem cuttings, Delgado and Yuyama (2010) showed that the species presents high rooting rates due to the fact that root formation occurs before sprouting. This behavior, according to the authors, allows the cuttings to allocate their reserves for root formation instead of sprouting.…”

Buxus sempervirens L., popularly known as boxwood, is a woody shrub widely used in gardening and landscaping. One of the most important factors for B. sempervirens commercial production is its propagation. The objective of this study was to evaluate the effect of indolebutyric acid (IBA) concentrations on the adventitious rooting of semihardwood stem cuttings of the species. Branches with new shoots were collected from stock plants with approximately 17 years of growth. Stem cuttings of six centimeters in length with two leaves in the upper region were made with a straight cut at the apex and a bevel cut at the base. Cuttings bases were immersed for 10 seconds in hydroalcoholic solutions (50% v v-1) with IBA at 0, 1500, 3,000 or 6,000 mg L-1. The cuttings were evaluated at 64 and 116 days after planting. Rooting, mortality, callus formation and sprouting percentages as well as root number and root length were measured. At 64 days, no significant percentage of rooting was observed in B. sempervirens stem cuttings and sprouting and callus formation were not significantly affected by the treatments. Keeping the cuttings in the greenhouse for 116 days led to rooting rates up to a 97.5%, with no statistical difference among treatments. Root lengths and root numbers did not differ as a function of treatments. The required period for B. sempervirens stem cuttings rooting is around 116 days; IBA application does not affect rooting, survival or sprouting of B. sempervirens stem cuttings.
