Etiolation and indolbutyric acid in the Olea europaea cv. Maria da Fé minicuttings

Abstract: This study aims to evaluate the effect of etiolation and the usage of indolbutyric acid (IBA) in the propagation of Olea europaea cv. Maria da Fé minicuttings. The experimental outline is a completely randomized design, with a 2 x 3 bifactorial scheme [minicuttings from plants with and without etiolation and three concentrations of indolbutyric acid (0, 1,000, and 2,000 mg L -1 )]. After 110 days, the following has been evaluated: percentage of survival, foliar retention and rooting, number of roots, length of… Show more

“…The 30×30TS and 10×10 plantations produced the least fresh matter of sprout (12.1 g and 10.2 g in season 1, 10.5 g and 9.2 g in season 2, respectively) and leaf matter per sprout (9.7 g and 7.1 g in season 1, 8.1 g and 6.0 g in season 2, respectively) (Table 1); probably the denser canopy and higher stand of these respective cultivation systems induced etiolation on sprouts that were elongated with thinner stems and smaller leaves as result of higher competition for light (Frölech et al, 2020). We also have to consider here source-sink relationship, seeing that stronger sink from planting systems was expected, which had higher density of plants or no thinning, because in these cases sprouting of them was higher; consequently, they produced higher number of sprouts, which means higher strong sink and lower strong source in comparison with the other planting systems.…”

“…Assim como, Koyama et al (2019) observaram maior enraizamento de estacas de mirtileiro com lesão na base e coletadas no verão. A realização da lesão na base das permite que haja rompimento de barreira física causada pelos anéis de esclerênquima (Fachinello et al 1995), deixando o tecido parenquimático exposto. Por ser constituído de células potencialmente meristemáticas, o mesmo apresenta grande importância no processo de regeneração e formação celular (Apezzato-da-Glória e Carmello-Guerreiro, 2006), podendo assim, favorecer a emissão de raízes.…”

“…De acordo com a literatura, o espinafre da Amazônia é facilmente propagado por meio de estacas da planta, possui rápido enraizamento, principalmente em locais favoráveis para o seu desenvolvimento (KINUPP; LORENZI, 2014). A técnica de estaquia, principalmente utilizada no setor agrícola, no cultivo de frutíferas e espécies florestais, como o eucalipto, que consiste na manutenção de cepas produzidas a partir de propagação da planta matriz, após a poda apical das mudas, confeccionados de estacas (FISS et al, 2017;MOREIRA et al, 2017;SILVA et al, 2022).…”

“…Alguns estudos com a utilização estacas de pequenas dimensões e com presença de gemas já foram realizados em espécies de importância comercial, como a oliveira (Olea europaea L.) (FRÖLECH et al, 2020), erva-mate (Ilex paraguariensis A. St.-Hil) (PIMENTEL et al, 2020), o pessegueiro (Prunus persica L.) (FISS et al, 2017); a batatadoce (Ipomoea batatas L.) (NASSER et al, 2020), assim como também, plantas alimentícias não-convencionais como o fisalis (Physalis peruviana L.) (OLIVEIRA et al, 2020), e ora-pro-nobis (TOFANELLI; MOGOR, 2021), entre outras espécies que tiveram resultados promissores com esse tipo de método de propagação vegetativa.…”
