“…The mini-cuttings technique aiming propagation of ecological interest species has generated satisfactory results, such as those observed in the works developed for Calophyllum brasiliense (SILVA et al, 2010), Liquidambar styraciflua (WENDLING et al, 2010) and Piptocarpha angustifolia (STUEPP et al, 2017). According to Xavier et al (2003) the mini-cuttings technique provides higher quality, higher velocity and higher rooting percentages for propagules when compared to the conventional cuttings technique.…”

“…According to Dias et al (2011), increased stem sugar content may indicate that it acted as a source of photoassimilates and, including soluble sugars, to promote sprouting (HARTMANN et al, 2011). It should be emphasized that the mini-cuttings technique favors the juvenility maintenance of these propagules, thus reducing the effects generated by maturation in woody species (FRAGOSO et al, 2016;STUEPP et al, 2017).…”

“…In these cases, if applied consistently, vegetative propagation could be an excellent alternative for plants production for environmental purposes, supplanting the lowest genetic variability by using a larger number of matrices to produce initial propagules (WENDLING et al, 2005;CARPANEZZI, 2006). The challenges for vegetative propagation include overcoming the effects of maturation in woody species, which are seen in physiological and biochemical alterations of donor plants (OSTERC; ŠTAMPAR, 2011), with consequent losses in rooting capacity (OSTERC;ŠTAMPAR, 2011;WENDLING et al, 2014) and root vigor (STUEPP et al, 2017).…”

“…Using plantlet production techniques such as mini-cuttings has evolved the vegetative propagation of woody species, especially by reducing the effects generated by maturation in those species with high ontogenetic age (STUEPP et al, 2017). The mini-cuttings technique has not yet been reported for F. enormis, however, cuttings were efficient in rooting and producing quality plantlets for the species (FRAGOSO et al, 2016).…”

Ficus enormis is a native species with great ecological potential, especially for ecosystems restoration. The present study aimed to evaluate the rooting, root and vegetative vigor of Ficus enormis mini-cuttings and to determine its best length for the formation of seedlings. Mini-cuttings were collected from clonal mini-garden, prepared with 2 ± 0.2 cm, 4 ± 0.2 cm, 6 ± 0.2 cm, 8 ± 0.2 cm and 10 ± 0.2 cm of length and diameter of 0.5 ± 0.2 cm. The planting was carried out in plastic boxes filled with commercial substrate based on carbonized rice hulls and coconut fiber, conditioned in a greenhouse. After 45 days, were avaluated the rooting percentage, original leaf maintenance, mini-cuttings with roots and callus percentage, length of the three largest roots/mini-cutting, shoot emission percentage, number of root/mini-cutting and mortality percentage. The results showed that the mini-cuting length did not influenced the rooting percentage, callus and root formation, and root length mean. However, shoot emission, number of root and mortality were influenced by the mini-cutting length.

Piptocarpha angustifolia is a potential native species for Brazilian forestry. However, a lot of challenges and technical constraints persist, hindering its expansion as a species for forest plantations, among them, the lack of evaluation of their survival and growth in field conditions. Thus, we evaluated the survival and growth vigor of Piptocarpha angustifolia according to two initial heights of mini-cuttings at planting. Plants from mini-cuttings with 20 ± 5 cm and 40 ± 5 cm were planted in field using 3 × 2 m spacing. In these, we evaluated the survival, base diameter and total height during 24 months. The experiment was implemented in a completely randomized design in a split plot model. Plants of 20 ± 5 cm are superior in survival to 40 ± 5 cm ones. The growth in height and diameter remained constant up to 24 months, reaching 64.1 cm and 13.5 mm, independently of the plants expedition time. In general, the establishment of clonal plantation of Piptocarpha angustifolia was limited by the attack of pests, mainly cutting ants. For this reason, plantation of this species must take into account the possibility of greater pest control. SILVICULTURA CLONAL DE Piptocarpha angustifolia: SOBREVIVËNCIA E VIGOR DE CRESCIMENTO A CAMPORESUMO: Piptocarpha angustifolia (vassourão-branco) é uma espécie nativa potencial para a silvicultura brasileira. No entanto, uma série de desafios e limitações técnicas ainda persistem, dificultando sua expansão como espécie para plantios florestais, dentre eles, a falta de avaliação de sua sobrevivência e crescimento em condições de plantio a campo. Assim, o presente estudo objetivou avaliar a sobrevivência e o vigor de crescimento em condições de pleno sol a campo de mudas clonais de Piptocarpha angustifolia em função da altura inicial das mudas, no momento do plantio. Mudas provenientes de miniestaquia com 20 ± 5 cm e 40 ± 5 cm de altura foram plantadas a campo em espaçamento 3 × 2 m. Nestas, foram avaliadas a sobrevivência, o diâmetro da base e a altura total ao longo de 24 meses. O experimento foi conduzido num delineamento inteiramente casualizado, em parcelas subdivididas no tempo. Mudas de 20 ± 5 cm mostraram-se superiores em sobrevivência às de 40 ± 5 cm. O crescimento em altura e diâmetro manteve-se constante até os 24 meses, alcançando 64,1 cm e 13,5 mm, independente da altura de expedição das mudas. De modo geral, o estabelecimento de plantios clonais de Piptocarpha angustifolia foi limitado pelo ataque de pragas, principalmente formigas cortadeiras. Por essa razão, a recomendação de plantios desta espécie precisa levar em conta a possibilidade de um maior controle de pragas.

The objective of this study was to evaluate the viability of the Ginkgo biloba mini-cutting technique, as well as the influence of substrates and different concentrations of indole butyric acid (IBA) on adventitious rooting in addition to the protein and sugar content in the mini-cutting. Mini-cuttings were 4 ± 1 cm in length, with the bases immersed in solutions of 0, 1000, 2000, and 3000 mg L-1 IBA. They were then planted in polypropylene tubes using two substrates (vermiculite and Tropstrato®) and maintained under greenhouse conditions for 60 d. The experiment was carried out with a 2 × 4 factorial scheme (substrates × IBA). There was no influence of IBA application on the promotion of rhizogenesis in Ginkgo biloba mini-cuttings. The rooting percentages were higher than 55% regardless of the treatment used. The vermiculite substrate showed a higher number of roots (4.94) and lower mortality (11.60) of mini-cuttings than Tropstrato®. We conclude that the mini-cutting technique is feasible for Ginkgo biloba, and the use of IBA is not necessary. We found that the induction ofadventitious rooting depended on the biochemical composition of the mother plants, due to the translocation of non-reducing sugars and leaf proteins for root formation.
