“…cuttings is influenced by genetic factors, management of the mother tree and of the rooting environment, collection season and degree of lignification of the cuttings. Due to all these factors, the results have been quite variable; however, it is possible to obtain rooting percentages higher than 70% with herbaceous, semi-hardwood or woody cuttings of scion peach tree cultivars (DUTRA et al, 2002;MINDÊLLO NETO et al, 2008), scion plum trees (MINDÊLLO NETO et al, 2006), of P. persica rootstocks (NACHTIGAL, 1999;TOFANELLI et al, 2005) and rootstocks of other species or interspecific hybrids of Prunus spp. (MAYER et al, 2001;MAYER et al, 2013;RADMANN et al, 2014a;MAYER et al, 2015).…”

Nursery trees of stone fruits (Prunus spp.) are traditionally produced by union of two distinct genotypes - the rootstock and the scion - which, by grafting, form a composite plant that will be maintained throughout of all plant life. In Brazil, the rootstocks are predominantly seed propagated and therefore usually results in heterogeneous trees for vigor and edaphic adaptation. However, with advances in rootstock breeding programs that released cultivars and certification in several countries (notably in Europe), the system will come gradually evolving for vegetative propagation (cuttings and tissue culture) and use of seeds of selected rootstocks with specific characteristics and potted nursery trees production. For scion cultivar propagation, the budding system (with its many variations) has predominantly been adopted in major producing countries. This review had as objective to comment main propagation methods adopted for rootstocks and scion in peach, nectarine and plum, and recent technical progress obtained as well as the needs of improvement for nursery tree production.

“…Chalfun e Hoffmann (1997) descreveram que um dos fatores a ser considerado visando o aumento na produtividade do pessegueiro é a utilização de mudas de qualidade na implantação do pomar e, dentre os métodos de propagação, pode-se utilizar a enxertia de borbulhas em porta-enxertos oriundos de sementes (TOFANELLI; RODRIGUES; ONO, 2005). No entanto, um dos inconvenientes da propagação sexuada é a variabilidade genética devido à polinização cruzada, que pode acarretar a perda de características genéticas desejáveis, como a resistência a nematóides do gênero Meloidogyne apresentada pelo porta-enxerto 'Okinawa' (PEREIRA; NACHTIGAL; ROBERTO, 2002).…”

A propagação de porta-enxertos de pessegueiro é feita normalmente por meio de sementes, mas esse processo pode levar à perda de características genéticas desejáveis, como a resistência a nematóides do gênero Meloidogyne apresentada pelo porta-enxerto 'Okinawa'. O objetivo deste trabalho foi avaliar o enraizamento de estacas de pessegueiro 'Okinawa' tratadas com ácido indolbutírico (AIB) em diferentes substratos, no outono. As estacas foram submetidas à aplicação de AIB em três concentrações (0; 1.000 e 2.000 mg L -1 ) por imersão rápida da base das estacas, em três substratos (areia, vermiculita e casca de arroz carbonizada). A estaquia foi realizada em caixas plásticas contendo os substratos, em câmara de nebulização. O delineamento experimental foi o inteiramente casualizado, com 5 repetições em arranjo fatorial 3 x 3, sendo cada parcela composta por 10 estacas. Após 108 dias verificou-se que a aplicação de AIB na concentração de 2.000 mg L -1 mostrou-se mais eficiente no enraizamento das estacas de pessegueiro nos substratos casca de arroz carbonizada e vermiculita, com enraizamento de 58 a 68%. Palavras-chave: Prunus persica (L.) batsch, raízes, propagação, vermiculita, casca de arroz carbonizada AbstractThe propagation of peach rooststocks is mainly done by seeds, but this method can result in the loose of interesting characteristics, like the resistance of 'Okinawa' rootstock to Meloidogyne spp. nematodes. The aim of this study was to evaluate the rooting of 'Okinawa' peach cuttings treated with different concentrations of indole butyric acid (IBA) on different substrates, in the fall. Cuttings of peach trees were subjected to application of IBA at three concentrations (0, 1000, and 2000 mg L -1 ) by rapid immersion of the cuttings in three substrates (sand, vermiculite, rice hulls). Cutting was performed in plastic boxes containing the substrates in a mist chamber. The experiment was randomized with 5 replications in a 3x3 factorial arrangement, where each plot was composed by 10 cuttings. After 108 days it was found that application of IBA at a concentration of 2000 mg L -1 was more effective on rooting of peach cuttings in the substrates carbonized hulls and vermiculite, with 58-68% of rooting.

“…The production of peach seedlings, Prunus persica, in Brazil is mainly achieved by vegetative bud grafting, where the rootstocks are obtained from seeds (TOFANELLI et al, 2005). This rootstock propagation method, however, may result in the loss of desirable genetic traits, resulting in trees distinct from the mother tree.…”

Does propagation method affect the field performance of peach trees?

Worldwide, peach propagation has been performed mainly by grafting scions of desirable cultivars on rootstocks obtained from seeds. There are, however, other potential propagation methods not widely adopted due to the limited reports on the field performance of the resultant trees. This study addressed this knowledge gap and investigated the field performance of peach trees of the cultivar Maciel that were established in an orchard (5.0 m × 1.4 m spacing) in 2011. The trees were trained in a "Y" system, with seedlings from three propagation techniques: 1) Conventional System (CS) -vegetative bud grafting of the scion on the rootstock of the Okinawa cultivar obtained from seed; 2) Rootstock by Minicutting (RM) -vegetative bud grafting of the scion on the rootstock of the Okinawa cultivar obtained by minicutting in a semi-hydroponic system; 3) Self-Rooting (SR) -self-rooting of the scion in a semihydroponic system. The vegetative, productive, and fruit quality parameters were assessed during 2012 and 2013. The Maciel peach trees that were propagated by the SR technique were found to have similar or even superior field performance to those propagated by the CS. The RM propagation method was also found to be an important potential alternative to peach propagation, since this it combines two techniques (cutting and grafting) to reduce tree vigor, especially if the goal is high-density planting. Key words: Prunus persica. Cloning. Self-rooting. Minicutting. ResumoEm todo o mundo, a propagação de pessegueiro tem sido realizada principalmente por enxertia de cultivares copa em porta-enxertos obtidos a partir de sementes. No entanto, existem outros métodos de propagação potenciais que não são amplamente adotados devido à pouca informação em relação ao desempenho a campo das plantas. A fim de responder a esta pergunta, em 2011, pessegueiros da cultivar Maciel foram plantados (5,0m ×
