“…According to the scientific literature, P. actinia stem cuttings root easily, achieving rooting rates of at least 40% without exogenously applied plant growth regulators (CHAVES et al, 2004;KOCH et al, 2004;ALBUQUERQUE JUNIOR et al, 2013). The present study corroborates these findings, with an average 51.27% rooting percentage ( Figures 1A and 2A).…”

Passiflora actinia Hook (common name: ‘maracujá do mato’) is an important medicinal species due to significant sedative and anxiolytic activities. In order to commercially exploit the plant, however, studies on propagation to improve rooting in stem cuttings are needed. The present study was designed to evaluate the effect of the brown seaweed (Ascophyllum nodosum (L.) Le Jol.) extract when applied on P. actinia stem cuttings bases. Five concentrations of the extract in distilled water were evaluated: 0% (pure distilled water), 10%, 20%, 30% and 40%. The experimental design was completely randomized with 4 repetitions and 12 cuttings per experimental unit. Cuttings were evaluated 45 days from planting. Data were analyzed through polynomial regression analysis and Pearson’s correlation coefficients were calculated for all the variables. On average, 51.27% rooting was achieved. Rooting percentage increased linearly according to the brown seaweed extract concentrations. When compared to the control treatment, about 10% increase in rooting was observed at the treatment with 40% seaweed extract. Leaf retention response to A. nodosum increasing concentrations was also adjusted in a positive linear model. A 15.6% increase in leaf retention was observed at the 40% seaweed concentration when compared to the control. Positive correlations were observed for leaf retention and rooting percentage and leaf retention and roots length. The immersion of P. actinia stem cuttings bases in A. nodosum extract at a concentration of 40% promote positive effects on rooting and facilitate the species propagation.

“…In this case, the epigenetic variation originated from the topophysis effect (effect of origin), that is, effect of position in the branch, is more evident as the physiological age advances. In Passiflora actinia there was greater rooting in basal cuttings with leaves (75%) than in middle cuttings with leaves (41.75%), while the apical cuttings died (Albuquerque Junior et al 2013).…”

Genetic diversity allows identification of potential intraspecific genotypes in the genus Passiflora. The objective of this study was to examine the morphological and genetic diversity of auxin-induced Passiflora mucronata. The experiments were arranged in a complete randomized block design, with a 9 x 2 factorial arrangement (nine genotypes x presence and absence of auxin, indole-3-butyric acid (IBA)), with four replicates of 16 cuttings. The rooting and vegetative growth responses were variable. Genotype 5 was more responsive in the absence of IBA and genotypes 3, 8 and 9 were more responsive in the presence of IBA. Auxin increased rooting rate and percentage, reducing the average time of root protrusion in eight days. IBA also contributed to increase photosynthesis and dry root and shoot mass in 55.55 and 44.44% of the genotypes, respectively. The highest relative contribution to phenotypic diversity in the absence of auxin was rate (38.75%) and percentage (20.27%) of rooting, whereas in the presence of auxin was stomatal conductance (23.19%) and root dry mass (20.91%). Similarity was found for phenotypic and molecular divergence in the presence of IBA, in which genotypes 1 and 6; genotypes 5, 8 and 9; and genotype 3 were clustered in distinct groups.

“…A determinação do volume de raízes foi realizada por diferença de volume, a partir de raízes colocadas no fundo de uma proveta de 20 mL e adicionado sobre as mesmas 5 mL de etanol 96%, de modo a não existirem bolhas de ar. Para a determinação da massa de matéria seca de raízes e brotações (g), estas foram secas em estufa à 65° C até a obtenção da massa constante (JUNIOR et al, 2013).…”

RESUMOO cipó-de-são-joão (Pyrostegia venusta (Ker-Gawl.) Miers) é uma trepadeira semilenhosa, vigorosa, nativa, com ocorrência em todos os biomas brasileiros e com potencial ornamental. Informações técnicas sobre a propagação desta espécie irão contribuir para a produção de mudas e com isso, o seu maior uso no paisagismo. O objetivo do trabalho foi avaliar a influência do número de folíolos e nós no enraizamento de estacas semilenhosas de cipó-de-são-joão. O experimento foi conduzido sob condições de câmara de nebulização intermitente. O delineamento experimental utilizado foi de blocos casualizados em fatorial 2 x 3, sendo respectivamente estacas com um ou dois nós, e zero, um ou dois folíolos. Utilizaram-se quatro repetições com parcelas experimentais constituídas por 12 estacas acondicionadas em substrato de casca de arroz carbonizada, em bandejas de poliestireno expandido com 72 células. Avaliou-se aos 84 dias: o percentual de estacas enraizadas; o comprimento de brotações, a massa seca de brotações, e, por estaca enraizada, a média de: número de raízes -de primeira ordem; comprimento máximo de cada raiz de primeira ordem, volume e a massa seca de raízes. Observou-se que estacas com dois folíolos possibilitaram 66% de enraizamento, maior comprimento e massa seca de brotações. A maior qualidade do sistema radicular ocorre com estacas com dois folíolos e dois nós. A propagação de cipó-de-são-joão é eficiente através do uso de estacas semilenhosas, contendo dois nós e dois folíolos, mantidas em casa de vegetação sob nebulização intermitente.

ABSTRACT Influence of leaf number and nodes on the rooting of semiwoody cuttings of flame vineThe flame vine (Pyrostegia venusta (Ker-Gawl.) Miers) is a semihardwood vine, vigorous, native, native, occurring in all Brazilian biomes and ornamental potential. Technical information about the propagation of this species will contribute to the production of seedlings and with that, their greatest use in landscaping. This study aimed to evaluate the influence of the number of leaves and nodes in rooting intermediate flame vine. The experiment was conducted under conditions of intermittent mist. The experimental design was a randomized block in factorial 2 x 3, being respectively cuttings with one or two nodes, and zero, one or two leaflets. We used four replicates with plots consisting of 12 cuttings placed in substrate of rice hulls in polystyrene trays with 72 cells. We evaluated at 84 days the porcentage of rooted cuttings, length of shoots, dry weight of shoots and, per cutting, average: number of roots -first order; maximum length of each root of the first order, volume and dry weight of roots. It was observed that cuttings with two leaflets enabled 66% of rooting, greater length and dry mass of shoots. The higher quality of the root system occurs with stakes with two leaflets and two nodes. The spread of flame vine is efficient with semi-hardwood cuttings with two nodes and two leaflets, kept in a ...
