“…This demonstrates that the species has the potential to take root during colder periods, and, depending on the stock plant, with practically the same success rate compared to spring/ summer, a more favorable period for root production and growth (MARANGON and BIASI, 2013). According to Trueman et al (2013), the temperature is one of the most important factors for rooting of cuttings, especially in species of the genus Eucalyptus, which require temperatures between 25 and 30 °C.…”

Sequoia is a fast-growing, long-living species, producing durable timber. The aim of this study was to test different methods for the vegetative rescue of Sequoia sempervirens trees over 40 years old, made at different periods of the year, and, later, testing the rooting of individualized cuttings in planned arrays. Twenty-four individual sequoias were rescued, applying girdling and semi-girdling at three different heights (-10, 0, and 30 cm). The first collection was made 90 days after application of the treatments, being repeated at 150, 240, and 360 days. The percentage of budding trees and the number of shoots per array were registered. In all collections, shoots produced cuttings, which were placed for rooting in mini-tunnels. Cutting survival (%), rooting (%), and number of roots were registered, per array, and per collection. The species vegetative rescue proved to be efficient for the production of shoots for stem cuttings, especially with girdling at 30 cm and semi-girdling at -10 cm. However, it is difficult to define the best method, mainly because of the genetic effect among stock plants. The rooting of cuttings, of recovered material, presented good results (average >65%), also with great differences among stock plants. The potential for rooting of cuttings varied according to different planting periods, with high rooting rates in all seasons, especially in summer. Sequoia sempervirens shows the potential for vegetative rescue and cloning by rooting of cuttings, and this may lead to new studies, with a view towards fixing clones. RESGATE VEGETATIVO E ENRAIZAMENTO DE ESTACAS DE DIFERENTES MATRIZES DE Sequoia sempervirensRESUMO: Sequoia é uma espécie de rápido crescimento, longeva e de madeira durável. O objetivo do estudo foi testar diferentes métodos de resgate vegetativo em árvores com mais de 40 anos de idade de Sequoia sempervirens, realizados em distintas épocas do ano e posterior enraizamento de estacas individualizadas por planta matriz. Resgataram-se 24 indivíduos de sequoia, aplicando-se anelamento e semianelamento em três diferentes alturas (-10, 0 e 30 cm). A primeira coleta foi efetuada 90 dias após aplicação dos tratamentos, sendo repetida aos 150, 240 e 360 dias. Contabilizou-se a porcentagem de árvores com brotações e o número de brotações por matriz. Em todas as coletas as brotações originaram estacas que foram colocadas para enraizar em estufim. No enraizamento das estacas analisou-se a sobrevivência (%), enraizamento (%) e número de raízes por matriz por coleta. O resgate vegetativo da espécie mostrou-se eficiente na produção de brotações para a estaquia, destacando-se o anelamento a 30 cm e o semianelamento a -10 cm. Entretanto, há dificuldade em definir qual o melhor método, principalmente em função do efeito genético entre matrizes. O enraizamento de estacas do material resgatado apresentou bons resultados (média >65%), também com grande diferença entre as matrizes. Diferentes épocas de estaquia alteraram o potencial de enraizamento, contudo, com altos índices de enraiz...

“…In general, for semihardwood cuttings, the leaves must be cut in half to avoid water loss and to facilitate the management (Fischer et al, 2008;Trevisan et al, 2008;Ristow et al, 2009;Marangon & Biasi, 2013). An alternative to optimize the material available to nursery production is to use in vitro propagation protocols.…”

“…In addition, it is important to emphasize that some blueberries varieties or cultivars present difficulties on rooting, and the use of growth regulators as indolebutyric acid (IBA) are required Fischer et al, 2008Fischer et al, , 2013Penã et al, 2012;Marangon & Biasi, 2013). Associated to growth regulators, the collect cuttings season, stem types, substrates and other variables can affect the cuttings rooting and root development Yamamoto et al, 2013;Colombo et al, 2018).…”

The nursery plants supply is one of the most important factors that limites blueberries production in some areas, due to some propagation difficulties observed on this species. In this way, this study aimed to evaluate substrates and IBA application methods on 'Powderblue' blueberries (Vaccinium ashei) minicuttings rooting, as well as to verify the rooting development in different periods. The study was divided in two experiments. The first one aimed to evaluate 'Powderblue' blueberry minicuttings rooting in three substrates (pine bark, carbonized rice husk and vermiculite) in response to two indolebutyric acid (IBA) application methods: 50% alcohol solution and talc. The second experiment aimed to evaluate 'Powderblue' blueberry minicuttings rooting using the best substrate recorded in the first trial (pine bark) and two IBA application methods associated to three periods of rooting access, in order to obtain the ideal rooting period and root development. In the first experiment the rooting percentage presented significant difference among the substrates; the higher percentage of rooted minicuttings occurred in pine bark substrate (68%). Regarding the methods used to IBA application, the talc method was more efficient to promote minicuttings rooting. In the second experiment, it was observed an increase in cutting rooting percentage from 55 to 84%, according to the evaluated seasons; however, the IBA application method did not influence the rooting percentage. Therefore, to produce 'Powderblue' blueberry plants from minicuttings it is recommended to use pine bark as substrate and talc as method to IBA application, transplanting the nurseries at 110 days after planting.

“…há, conforme mencionado, diferenças nas respostas ao enraizamento, quando utilizado regulador de crescimento, em função da espécie com a qual se está trabalhando, evidenciado por Tofanelli et al (2003), que, comparando a forma de aplicação do regulador de crescimento (aiB) no enraizamento de pessegueiro, observaram que os melhores resultados são obtidos quando do uso da imersão rápida, diferente do verificado neste trabalho, e por Marangon et al (2013) que, em trabalho com aplicação de aiB visando ao enraizamento de mirtilo, verificaram que o aumento da concentração do regulador de crescimento foi acompanhado do aumento da percentagem de enraizamento até a maior concentração testada (2000 mg.l -1 ), também diferindo do encontrado no presente trabalho.…”

Realizou-se o presente trabalho objetivando avaliar a propagação de três variedades de caramboleira por estaquia em função da dose de regulador de crescimento (ácido indolbutírico - AIB), empregada no tratamento das estacas. Foram utilizadas estacas herbáceas apicais, sendo o experimento conduzido em câmara de nebulização intermitente, localizada em condições de ripado (50% de luminosidade). As estacas das variedades B10, Hart e Golden Star receberam o tratamento com AIB, nas doses de 100; 200 e 400 mg.L-1 (imersäo lenta) e nas doses de 1.000, 3.000 e 5.000 mg.L-1 (imersäo rápida), mais tratamento-testemunha (0 mg.L-1 de AIB). As avaliações, 90 dias após a estaquia, foram quanto: porcentagens de sobrevivência, calejamento e enraizamento; número médio de raízes por estaca e comprimento médio das raízes (cm). O delineamento experimental foi o inteiramente casualizado, com quatro repetições por tratamento, compostas por 10 estacas, analisado em fatorial 3 x 7 (variedades x AIB). Conforme resultados obtidos neste trabalho, näo há necessidade do tratamento das estacas de caramboleira com regulador de crescimento (AIB). A variedade Golden Star mostrou melhores resultados, seguida pela Hart e B10.
