“…A diferencia de los resultados obtenidos por Latsague et al (2010), en este estudio se observa el efecto significativo de la auxina sobre el enraizamiento, siendo más evidente en estacas juveniles, situación también descrita para D. melanoxylon (Amri et al 2010). Al aplicar AIB también se mejora la calidad del sistema radical, porque aumenta el número de raíces y la longitud de estas, aunque sin efectos significativos, este comportamiento coincide con lo reportado para U. molinae (Rodríguez et al 2015) y B. corallina (Uribe et al 2011).…”

SUMMARYAmong the species that live in wetlands Myrceugenia exsucca is a highly important tree for the protection of areas with frequent flooding, edges in watercourses and streams. This study therefore is aimed at evaluating the effect of the application of indole butyric acid (IBA) and the age of the material on rooting in the M. exsucca cuttings. A completely randomized design, factorial, with two types of cutting: juvenile and mature, and six concentrations of IBA (0, 1,000, 2,000, 3,000, 4,000 and 5,000 mg L -1 ) were tested. Six replications; each replicate consisted of 10 cuttings. The trial was conducted in a warm bed, with temperatures between 20 and 25 °C. The variables studied were: survival (%), callus formation (%), rooting (%), root number, root length (cm) and new leaves. The age of cuttings had significant effects on all variables. The application of IBA had significant effects on the survival and rooting cuttings. The best results, over 85 % of rooting were obtained with cuttings from juvenile material and with the two higher doses of IBA.Key words: Myrceugenia exsucca, vegetative propagation, swamp forest. RESUMENEntre las especies que habitan humedales se encuentra Myrceugenia exsucca, árbol de gran importancia para la protección de áreas con frecuente anegamiento, orillas en cursos de agua y quebradas. El objetivo del estudio fue evaluar el enraizamiento de M. exsucca al usar dos tipos de esquejes y aplicar distintas concentraciones de ácido indolbutírico (AIB). Se usó un diseño completamente aleatorizado, factorial, con estacas juveniles y maduras y se probaron diferentes concentraciones de AIB (0, 1.000, 2.000, 3.000, 4.000 y 5.000 mg L -1 ). Se hicieron seis repeticiones, cada una de ellas con 10 estacas. El ensayo se realizó en cama caliente, con temperaturas entre 20 y 25 °C. Las variables estudiadas fueron: sobrevivencia (%), estacas con callo (%), enraizamiento (%), número de raíces, longitud de raíces (cm) y número de hojas nuevas. La edad de la estaca influyó significativamente en todas las variables evaluadas. La aplicación de AIB afectó significativamente la sobrevivencia y enraizamiento de esquejes. Los mejores resultados, sobre 85 % de estacas enraizadas, se lograron con esquejes provenientes de material juvenil y con las dos mayores dosis de AIB.Palabras clave: Myrceugenia exsucca, propagación vegetativa, bosques higrófilos.

Currently there is a great demand for food products containing functional properties and/or bioactive compounds. One of the fruits that has been widely studied is the murta (Ugni molinae), which appears to contain various beneficial health properties. This review compiles scientific information on the functional and beneficial properties of murta for human health, such as the main components associated with anti-inflammatory activity, antimicrobial activity, antioxidant activity, nutritional composition, other uses of murta, economic aspects, and current and future challenges of murta, all based on updated scientific work.

“…Shoots cultured in NAA supplied medium formed three times more roots than those cultured in the absence of NAA; the response even increased when compared to previous arrow cane in vitro rooting studies Suárez et al, 2009). Good quality in vitro rooting is not only the formation and proliferation of adventitious root but also root characteristics such as length and width (Benavides et al, 2016;Rodríguez et al, 2015;Zakavi et al, 2016). During the transfer to ex vitro conditions, shoots with shorter roots are easy to handle and do not require trimming, which produces stress and open wounds (Kane, 1996).…”

To evaluate the micropropagation response of arrow cane, Gynerium sagittatum (Aubl.), plants using a double-phase medium in the multiplication stage, explants consisting of stem sections with axillary meristems from cultivars Criolla, Criolla 1, and Martinera were established in vitro in a semisolid medium. Then, they were multiplied using a double-phase medium supplied at several Benzylaminopurine (BAP) concentrations (0.0, 0.5, 1.0, 1.5, and 2.0 mg/L), followed by rooting in a culture medium supplied at several Naphthaleneacetic acid (NAA) concentrations (0.0, 0.5, 1.0, 1.5, and 20 mg/L). Both multiplied unrooted and rooted microshoots were transferred ex vitro. Treatments were distributed with a completely randomized design; data were analyzed with an ANOVA and means separated with Tukey’s test. Explants from Criolla and Martinera cultured with 0.5 mg/L BAP resulted in higher multiplication rates. All microshoots transferred to the rooting medium rooted, although NAA significantly increased the number of roots and reduced root length. Plants from all three cultivars, in vitro rooted or unrooted transferred to ex vitro conditions, showed 100 % survival and adaptation. For Criolla and Martinera, 0.5 mg/L BAP statistically increased shoot multiplication rates and NAA increased adventitious root formation and reduced root length. Plants of all cultivars survived and adapted 100 % to ex vitro conditions.
