Production of self-rooted peach seedlings

Abstract

The use of mini-cuttings in the production of peach seedlings may prevent the inconvenience of grafting and make possible the fast, simple and low-cost production of a great number of seedlings, in a shorter period of time. Seedlings collection from self-rooted scion cultivars may be an option for locations where the use of rootstock does not offer any specific advantage. The objective of the present experiment was to evaluate the growth and survival of self-rooted peach scion cultivars cloned through mini-cutting under the soilless cultivation system and in packages with commercial substrate, in a greenhouse. The experimente used rooted herbaceous mini-cuttings from the Maciel and Bonão scion cultivars transplanted to a package with commercial substrate and to a soilless cultivation system as vegetal material. The Maciel cultivar showed greater rooting and survival percentages after transplantation when compared to Bonão. At 120 days after transplantation to the cultivation systems, self-rooted seedlings from the Maciel and Bonão cultivars reached half the length of a commercially ready seedling. The soilless cultivation system improves self-rooted peach seedlings development in relation to production in packages.

Rooting dynamics of Prunus minicuttings

“…Among the vegetative propagation processes, minicutting is an improvement of cutting technique and has been used in the multiplication of several plant species, such as eucalyptus (Eucalyptus benthamii) (Brondani, Baccarin, Ondas, Gonçalves, & Almeida, 2012), Australian cedar (Toona ciliata) (Silva, Barroso, Souza, Ferreira, & Carneiro, 2012), and also in several fruit trees, such as guava tree (Psidium guajava) (Marinho, Milhem, Altoé, Barroso, & Pommer, 2009;Altoé & Marinho, 2012), araçá (Psidium cattleianum) (Altoé, Marinho, Terra, & Barroso, 2011), soursop (Annona muricata) (Figueirêdo, Vilasboas, Oliveira, Sodré, & Sacramento, 2013), blueberry tree (Vaccinium spp.) (Fischer, Fachinello, Antunes, Fischer, & Giacobbo, 2013;Yamamoto et al, 2017;Koyama et al, 2018), peach tree (Prunus persica) (Timm, Schuch, Tomaz & Mayer, 2015a;Tomaz, Schuch, Peil, & Timm, 2014;Tomaz, Schuch, Peil, & Pereira, 2016;Ramm, Schuch, Fagundes, Silva, & Moreira, 2017), cherry (Ozelame, Affonso, Cappellaro, Schuch, &Tomaz, 2018, blackberry andraspberry (Sommer et al, 2016;Fagundes et al, 2016), and more recently the olive tree (Olea europaea) (Casarin, Moreira, Raasch, Timm, & Schuch, 2018;Moreira & Schuch, 2018).…”
