Influence of rootstocks on fruit physical and chemical properties of peach cv. UFSun

Abstract

The subtropical peach cultivar UFSun grafted on five different rootstocks ('Flordaguard', 'Barton', 'MP‐29', 'P‐22', and 'Okinawa') was investigated in terms of the pomological and biochemical parameters of the fruit. Significant differences in fruit weight and size, soluble solids content, titratable acidity, and firmness were found among some rootstocks. The fruit length and diameter were different between the 'MP‐29' and other rootstocks. It was also found that firmness of 'UFSun' fruit was affected by the rootstock. The highest firmness value was found when 'UFSun' was grafted on 'Flordaguard'.' 'MP‐29' fruit had the highest soluble solids content, but there were no differences among the other rootstocks. 'UFSun' fruit from trees grafted on 'MP‐29' were smaller and had the most intense color compared to 'UFSun' fruit from other rootstocks. Rootstock had a significant influence on total fruit phenolic compounds, anthocyanin content, and total antioxidant activity, with fruit from 'UFSun' on 'MP‐29' having the highest values in all of them. A high correlation between fruit total antioxidant activity and total phenolic content was found. Overall, the results showed that 'MP‐29' seems to induce the highest fruit quality, showing higher contents of total soluble solids, total titratable acidity, total phenolic compounds, total antioxidant activity, and total anthocyanin content. Selecting the right combination of the rootstock and cultivar is important for optimizing fruit quality parameters.

The Impact of Peach Rootstocks and Winter Cover Crops on Reproduction of Ring Nematode

“…Additionally, Beckerman et al [ 27 ] reported ‘MP-29’ to perform better than ‘Guardian’ not only for PTSL but also for another important root disease of peach called Armillaria root rot. Shahkoomahally et al [ 28 ] found ‘MP-29’ to induce higher soluble solids, titratable acidity, phenolic compounds, antioxidant activity, and anthocyanin content in fruits, suggesting peaches grafted on ‘MP-29’ have better fruit quality. Although ‘MP-29’ is considered to have some level of resistance against root-knot nematodes [ 27 ], studies are not available to prove its resistance against ring nematodes.…”

Influence of Scion/Rootstock reciprocal effects on post-harvest and metabolomics regulation in stored peaches

Cultivar-rootstock interactions on growth, yield and mineral nutrition of newly planted peach trees in a pot experiment

“…In the present experiment 'RP20' was the most dwarfing rootstock, with the rest of the rootstocks are considered invigorating ones. The differences found in the literature among rootstocks have been attributed, among others, to the genetic background of each rootstock (Zarrouk et al, 2005;Ben Yahmed et al, 2020;Shahkoomahally et al, 2021). It seems that peach-almond rootstocks, such as 'GF677' and 'Garnem', respond better to iron deficiency under calcareous soils (Zarrouk et al, 2005;Assimakopoulou et al, 2011;Mestre et al, 2015;Ben Yahmed et al, 2020), as well as some plum rootstocks (Mestre et al, 2015;Ben Yahmed et al, 2020), while peach cultivars grafted on all these rootstocks present high Ca concentration too (Ben Yahmed et al, 2020) Among the tested rootstocks, it seems that 'Andross' in 2018, as well as both cultivars in 2019, presented high leaf N concentration when budded on 'GF 677' (2018 and 2019 were the years when first fruit production occurred).…”

“…Therefore, nowadays, commercial peach trees consist of two different parts, i.e. the rootstock and the scion cultivar (Zarrouk et al, 2005;Zarrouk et al, 2006;Ben Yahmed et al, 2020;Shahkoomahally et al, 2021). The right choice of the rootstock and scion cultivar combination is probably the most important factor of the peach cultivation success (Reig et al, 2016;Özdemir et al, 2019;Santana et al, 2020;Shahkoomahally et al, 2020).…”
