Performance of Adafuel and Adarcias as Peach Rootstocks

Abstract

<jats:p>Field performance of several peach × almond hybrid [<jats:italic>Prunus amygdalo-persica</jats:italic> (West) Redh.] rootstocks grafted with different peach cultivars [<jats:italic>Prunus persica</jats:italic> (L.) Batsch] were tested for 11 to 12 years in three experiments. `Loadel' scions were grafted on Adafuel, Adarcias, Albatarrech, Calanda, and GF 677 hybrids. `Catherina' and `Flavortop' scions were grafted on Adafuel, Adarcias, and GF 677 hybrids. Adafuel was the most invigorating rootstock for `Loadel', after the 12 years of scion growth, but Adarcias also promoted higher scion productivity than other peach × almond hybrid rootstocks. Although there were no differences in `Catherina' productivity when grafted on different rootstocks, this cultivar and `Flavortop' grafted on Adarcias showed the least vigor. `Flavortop' on Adafuel had more vigor than on the other rootstocks. According to our results, Adafuel (a vigorous rootstock) seems to be suitable for peach production in low nutrient and calcareous soils unfavorable for peach seedling rootstocks. Adarcias seems promising as a peach rootstock for avoiding excessive scion growth, and it may be useful where tree size needs to be controlled.</jats:p>

Influence of rootstock on orchard productivity and fruit quality in peach cv. ‘Redhaven’

“…In the first bearing year (1999), and in 2003, we did not find any statistically significant differences between the different rootstocks in yield per tree and yield ha -1 , which agrees with results reported by Moreno et al (1994) in 'Catherina'. The lowest yield per tree and yield ha -1 were attained by trees grafted on P. pumila in 2000, 2001, 2002 and 2004.…”

Agronomic and physicochemical fruit properties of ‘Big Top’ nectarine budded on peach and plum based rootstocks in Mediterranean conditions

“…However, this has led growers to have no choice but to use replant soils, meaning soil and disease problems like root asphyxia, iron-chlorosis deficiency, waterlogging and soil-borne pathogens (Font i Forcada et al, 2014a;Mestre et al, 2015;Zarrouk et al, 2005), which affect the normal development of the tree. In order to solve that, and because the rootstock represents an important consideration for a productive orchard, particularly in orchard replanting situation (Bussi et al, 2002), breeding programs are very active in the release of new rootstocks, improving peach adaptability to the soil (Felipe, 2009;Pinochet, 2010;Moreno et al, 1994;1995) and to different training systems, and improving peach fruit quality (Monet and Bassi, 2008). Therefore, the accurate evaluation of rootstocks responses to different growth conditions and the identification of the best scionrootstock combination are of major importance to obtain high quality crops (Rato et al, 2008).…”

Changes in Cell/Tissue Organization and Peroxidase Activity as Markers for Early Detection of Graft Incompatibility in Peach/Plum Combinations

“…In the Mediterranean area, there is a widespread use of peach • almond hybrids (Prunus persica • Prunus dulcis) as peach rootstocks because they are tolerant and/or resistant to variety of biotic and abiotic stresses (Byrne et al, 1990;Felipe, 2009;Kester and Asay, 1986;Pinochet, 2009) and are generally graftcompatible with peach cultivars (Cambra, 1990;Moreno and Cambra, 1994;Moreno et al, 1994b). However, these rootstocks are known to be extremely vigorous (Wertheim and Webster, 2005;Zarrouk et al, 2005) and relatively sensitive to waterlogging (Okie and Weinberger, 1996).…”
