“…De acordo com Villa et al (2003), os cultivares Brazos e Guarani apresentaram diferentes potenciais de enraizamento e de desenvolvimento da parte aérea. Dias et al (2011) descrevem uma possível relação do teor de açúcar na parte aérea com o processo de enraizamento em estacas de amoreira-preta.…”

“…(2009), também estão relacionados com o N. Eles, em si, não aumentam a resposta ao enraizamento, mas, são fonte de energia e de carbono para a síntese de substâncias essenciais para a formação de raízes (Klopotek et al, 2012). O aumento dos teores de açúcares da parte aérea com relação aos das raízes pode indicar que a parte aérea atua como fonte de fotoassimilados e, dentre eles, de açúcares solúveis, para promover o enraizamento das brotações (Dias et al, 2011).…”

O objetivo deste trabalho foi avaliar o efeito da adubação nitrogenada, de plantas matrizes, no enraizamento de estacas de amoreira-preta. O experimento foi realizado na Embrapa Clima Temperado, Pelotas, RS. O delineamento experimental foi o inteiramente casualizado, em fatorial 2x5, ou seja, dois cultivares ('Tupy' e 'Xavante') e cinco doses de nitrogênio (N) (0,0; 7,5; 15,0; 22,5 e 30,0 g planta-1). Avaliaram-se a percentagem (%) de estacas enraizadas, com calo, vivas, brotadas, o comprimento da maior raiz e da maior brotação (cm), o número de raízes e de brotações por estaca. Quanto ao enraizamento e ao número de raízes por estaca verificou-se aumento linear com o acréscimo da dose de N aplicada na planta matriz, efeito contrário ao observado na variável calo. O comprimento da maior brotação, o número de raízes e de brotações, além da percentagem de estacas brotadas foram maiores no cultivar ''Xavante'' (2,68, 3,02, 1,22 e 52,08, respectivamente). Quanto à percentagem de estacas vivas destacou-se o cultivar 'Tupy' (98,55%). Por essa razão, conclui-se que o uso do nitrogênio em plantas matrizes pode ser benéfico ao enraizamento de estacas de amoreira-preta, bem como ao desenvolvimento inicial do sistema radicular e da parte aérea das novas plantas, porém com efeitos negativos aos parâmetros comprimento da maior raiz e percentagem de calo.

“…Larger and longer cuttings presented higher reserves amounts, which are used for sprouting and roots (Pizzatto et al, 2011). The presence of leaves is also a great influence factor for shoot sprouting, as they produce photoassimilates, among them soluble sugars, which are essential as an energy source for budding (Dias et al, 2011). to have more reserves, which are used after adventitious rhizogenesis, root system emission, as well as in aerial structures (Pizzatto et al, 2011).…”

Stem cuttings and substrates in Dovyalis asexual propagation

et al. 2018

The objective of this study was to evaluate the asexual propagation of Dovyalis, through the use of substrates and cuttings. Three experiments were conducted in Marechal Cândido Rondon, Paraná State, Brazil, and the first experiment consisted of three removal positions of the cuttings (apical, middle and basal) x 4 Indole butyric acid (IBA) concentrations (0 mg L-1, 1000 mg L-1, 2000 mg L-1 and 3000 mg L-1); the second experiment evaluated the number of leaves in the cuttings (2, 4 and 6) x 3 cutting sizes (10, 15 and 20 cm); and the third experiment evaluated four substrates for rooting. The experiment was carried out in a randomized blocks design, with the first in a 3x4 and the second in a 3x3 factorial, respectively, containing 4 repetitions of 15 cuttings. The third experiment consisted of 5 repetitions of 15 cuttings. After the IBA treatment, the cuttings were taken to rooting in sandy beds during 70 days. The agronomical variables were evaluated. Basal and middle cuttings resulted in root systems with better development. The use of 1666 mg L-1 of IBA favors the Dovyalis cuttings rooting. Cuttings with 15 and 20 cm with four leaves favors the Dovyalis vegetative propagation. Dovyalis cuttings develop better on substrates containing latosol and vermiculite.

“…Thus, the sprouting of shoots may be a source of photo-assimilates and/or substances that induce the rooting process and can be used for the formation of adventitious roots. However, the occurrence of sprouts before rooted cuttings can negatively affect the rooting since the reserves that would be used for it can be deviated to the sprouting process (Dias et al, 2011).…”

Umbuzeiro (Spondias tuberosa Arr. Cam.) is a plant native to Brazilian semi-arid regions. Currently, there is no protocol for propagation for this species. In this sense, the aim of this study was to evaluate the propagation of Umbuzeiro by cuttings, using ethephon and indolebutyric acid (IBA). In this study, a completely randomized statistical design was used with the doses of ethephon (0, 14.5, 50, 85.5, 100 mg L -1 ) and IBA (0, 872.35, 3000, 5127.65, 6000 mg L -1 ) combined by the matrix "Central Compound Box" in 4 replicates. After application of ethephon and IBA on plants, cuttings with 20 cm length were prepared and planted in tubes with sand and organic compound (1:1 v/v) and placed in a greenhouse at 50% light under misting. The percentage of sprouted cuttings, length and diameter of the shoots, the percentage of rooted cuttings, live cuttings with and without calyx, dead cuttings, number of roots and length, dry matter of roots, leaf and total dry matter were evaluated. A combination of the doses of 100 mg L -1 of ethephon and 6000 mg L -1 of IBA increased the percentage of sprouted cuttings, number of shoots per cutting, number of roots per cuttings and promoted the rooting of 47.20% of the Umbuzeiro cuttings. The shoot formation and dry matter of Umbuzeiro cuttings were not influenced by the doses of ethephon. The IBA doses increased shoot formation and dry matter production of the umbuzeiro cuttings under greenhouse conditions.
