“…dipping with the concentration of 2000, 3000 and 4000 ppm IBA increased in the number of roots. Sedaghathoor et al, (2016) had also studied the effect of planting substrate and concentrations of IBA and NAA hormones on the rooting of mugo pine cuttings in which both hormones IBA and NAA were applied at four concentrations of 0, 1000, 2000 and 4000 mg/l and highest rooting 55% was obtained under the treatment 4000 mg/l NAA+ 1000 mg/l IBA was found to be the best. So, we can say that IBA and NAA might be the good plant growth regulators for root initiation.…”

Background: Avocado (Persea americana Mill.) family, Lauraceae, sub-tropical evergreen tree, which is very nutritious fruit having large oil fraction which is one of the unique features and has good medicinal properties. The vegetative propagation of avocado has become increasingly important to produce a large amount of planting material. Methods: The present study was conducted in the research field at the Department of Horticulture, Sikkim University, Gangtok during 2016-2017 to evaluate the effect of different concentration plant growth regulators on the rooting of two cultivars. Hass and Fuerte Avocado (Persea americana Mill.) cuttings were investigated at the mist chamber. The experiment was laid in a completely randomized design for avocado cuttings of cvs. Hass and Fuerte with eighteen treatments comprising of different concentrations of IBA (control, 200 ppm, 400 ppm, 800 ppm, 1000 ppm) and NAA (control, 200 ppm, 400 ppm, 800 ppm, 1000 ppm). In all the treatments the cuttings were dipped in the plant growth regulators for 10 seconds. Rooting medium for planting the avocado cutting used was fine coarse vermiculite 80%, soil 10% and well rotten cow dung manure 10% in the ratio of 8:1:1 respectively for all the treatments. Result: In general, the results showed a significant increase for root initiation under treatment (IBA 800 ppm + Fuerte) followed by (IBA 400 ppm + Fuerte) which took 105.67 days for root initiation as compared to control at 5% level of significance. The avocado cuttings exhibited significant results for root initiation was 99.33 days which was recorded under treatment IBA 800 ppm + Fuerte as compared to treatment Fuerte (control) which was 121 days observed in root initiation. The maximum number of 14.05 roots at the time of transplanting in cuttings under treatment IBA 400 ppm + Fuerte and minimum was 2.00, 2.11, 2.22, 2.66 and 2.89 observed in treatment control + Hass, NAA 200 ppm + Hass, IBA 1000 ppm + Hass, IBA 200 ppm + Hass and IBA 400 ppm + Hass respectively. The maximum length of 1.53 cm root at the time of transplanting was found with treatment IBA 400 ppm + Fuerte and the minimum was 0.17 cm observed in treatment Hass (control). The rooting 72.22 percentage at the time of transplanting in cuttings was observed treatment IBA 400 ppm + Fuerte and minimum was 11.11 percentage observed in Hass (control). Fuerte with IBA 400 ppm was better in rooting capacity as compared to others.

“…La formación de raíces adventicias, parte esencial en la propagación vegetativa por estacas de especies maderables (Legué et al, 2014), es regulada por factores ambientales y reguladores de crecimiento (de-Klerk et al, 1999), y es promovida por altas concentraciones de auxinas y bajas de citocininas (Steffens y Rasmussen, 2016). Las auxinas tienen el efecto mayor en la formación de raíces adventicias; de manera endógena, el ácido indolacético (AIA) se encuentra en las ramas y hojas jóvenes (Sedaghathoor, Kayghobadi y Tajvar, 2016); aplicado de manera exógena, el ácido indol-3-butírico (AIB) es la auxina más utilizada para este propósito (de-Klerk et al, 1999). Guan et al (2015) mencionan que la formación de raíces se divide en tres etapas: 1) inducción, que incluye los eventos químicos y moleculares que preceden a los cambios morfológicos, 2) iniciación, donde la división y diferenciación celular permiten la formación de primordios y meristemos y 3) extensión, donde las raíces adventicias continúan su crecimiento y emergen.…”

“…de plantas de 12 meses, mientras que en plantas de mayor edad la favoreció. La aplicación de 4000 mg de AIB por litro de solución líquida, durante 10 segundos, en combinación con ácido 1-naftanelacético (ANA) en un sustrato de arena permitió 55% de enraizado en Pinus mugo Turra (Sedaghathoor et al, 2016). Otro estudio indica que en P. pinaster Ait., AIB en solución, por 10 segundos, a una temperatura de enraizado de 25 °C generó más de 90% de enraizado (Majada et al, 2011); mientras que en P. caribeae Morelet se observaron resultados favorables con 4000 mg L -1 de AIB aplicados en solución por dos segundos (Henrique et al, 2006).…”

El enraizado de estacas es una alternativa para la clonación masiva de árboles seleccionados, con características deseables y superiores para plantaciones comerciales. Sin embargo, la capacidad de enraizado disminuye rápidamente a los 2 o 3 años de edad en especies de coníferas. El objetivo de este trabajo fue evaluar la capacidad de enraizamiento de estacas de plantas madre de Pinus patula de 15 y 18 meses de edad, con diferente dosis de fertilización y condición de crecimiento (manejo), y con la aplicación de 5000 × 10-6 (5000 ppm) de ácido indol-3-butírico (AIB) en solución líquida o con el producto comercial Radix® en pasta. A las 14 semanas de establecido el ensayo se evaluó el porcentaje de supervivencia, estacas con callo y raíces, así como el número, longitud de raíces primarias y presencia de raíces secundarias. Se encontraron efectos significativos (p ≤ 0.05) en los factores evaluados y en su interacción. La aplicación de AIB en solución durante 10 s o 20 s ocasionó el mayor porcentaje de enraizamiento (> 25%), 2-3 veces más que el testigo (8.5%). La fertilización de la planta madre con 7 g L-1 de Osmocote® bajo malla sombra provocó una mortalidad elevada de las estacas (30%). No se encontraron diferencias en longitud de raíz más larga, ni en longitud promedio de raíces primarias. La combinación de planta madre de 18 meses con fertilización de 5 g L-1 de Osmocote® en invernadero y la aplicación de AIB en solución líquida por 20 s produjo 73.8% de enraizado, valor aceptable en un programa operativo de clonación de Pinus patula.

“…(d) Cold storage of cuttings before rooting -pine cuttings stored at 4°C for several weeks exhibited significantly higher rooting rates than cuttings that were rooted immediately after collection (Whitehill and Schwabe 1975). (e) Auxin treatment -there is a large number of studies showing improvement of rooting by auxin application in various pine species (Whitehill and Schwabe 1975;Ragonezi et al 2010;Sedaghathoor et al 2016). These studies included various auxins, such as indole-3-butyric acid (IBA), indole-3-acetic acid (IAA), and 1-naphthaleneacetic acid (NAA), different application methods, such as powder and solution, and for the latter treatment combinations of treatment duration and hormone concentration.…”

Forest trees possess high genetic diversity and high heterozygosity which allow adaptation to changing environmental conditions. There is a tendency to propagate successful and unique genotypes, which are identified at their mature stage in the forests, for future improvement programs and conservation purposes. However, vegetative propagation of mature forest trees is still a challenge in many conifers. In this study, we focused on improving the rooting of cuttings of mature and old Pinus halepensis and its hybrids. We observed that storage of cuttings before rooting at 4°C for 4 weeks and prolong immersion of cuttings in a solution containing 400 mg/l of indole-3-butyric acid, 5 mg/l of the auxin conjugate 2-(2,4-dichlorophenoxy)propanoic acid-glycine methyl ester, and 0.01% of Amistar fungicide significantly improved rooting of mature cuttings. The active ingredient in Amistar is azoxystrobin, an uncoupler of respiration, which seems to directly promote rooting. Rooted cuttings of selected clones demonstrated unique and uniform growth performance, most likely delivering the intrinsic growth parameters of the mother trees. It was also observed that trees growing under drought stress possess improved rooting ability. By using rooted cuttings, it will be possible to study the relationship between growth rate and adaptation to semi-arid climate conditions. The ability to clonal propagate mature and old P. halepensis trees not only enables vegetative propagation of elite trees for improvement programs, but also provides an opportunity to preserve unique naturally occurring old P. halepensis genotypes.
