Horticultural, leaf mineral and fruit quality traits of two ‘Greengage’ plum cultivars budded on plum based rootstocks in Mediterranean conditions

Abstract

Field performance, leaf mineral content and fruit quality of two 'Greengage' plum cvs. 'R.C. Bavay' and 'R.C. GF 1119' budded on two plum based rootstocks (Ishtara and P.8-13) were studied in the network of an international European plum trial, promoted by the Fruit Research Station of the INRA of Bordeaux (France) and other European Research Centers. Trees were established in the winter of 1993-1994 in a heavy and calcareous soil with climate conditions typical of the Mediterranean area. Trees of 'R.C. GF 1119' were more vigorous than those from 'R.C. Bavay'. The highest yield was observed on the P.8-13 rootstock for both cultivars. In contrast, the highest cumulative yield and yield efficiency were induced by 'R.C. Bavay', independently of the rootstock. All trees budded on Ishtara survived well, whereas tree mortality was reported in trees budded on P.8-13 for each cultivar. Leaf chlorophyll content varied depending of the rootstock-scion combination. Most of the mineral nutrient concentrations were not affected by the rootstock-scion combination, with the exception of Mn, which was significantly lower on Ishtara for both cultivars. Overall, Ishtara resulted the best adapted rootstock to soil waterlogging and calcareous soil conditions showing a good tree survival and best leaf Fe mineral content. Further studies with plum varieties budded onto P.8-13 rootstock should be carried out to in order to recommend their use on soils with no waterlogging and/or associated diseases. Comparing the two cultivars, 'R.C. Bavay' showed better agronomic performance than 'R.C. GF 1119', in terms of cumulative yield and yield efficiency, and similar good fruit quality.

Long-term graft compatibility study of peach-almond hybrid and plum based rootstocks budded with European and Japanese plums

“…Nevertheless, it has lower expected peach (up to 25%) and no almond in its genetic background as compared with peach-almond hybrids. Similarly, Reig et al (2018a) reported a good agronomic performance of Isthara with 'R.C. Bavay' and 'R.C.…”

“…The hexaploid European plums (Prunus domestica L.) and the diploid Japanese plums (Prunus salicina Lindl.) are among the most widely cultivated fruit species in temperate climates (Ferlito et al, 2015;Reig et al, 2018a). The commonly used rootstocks for European plum cultivars include different Prunus species such as Prunus cerasifera (Myrobalan or cherry plums, 2n=16), P. cerasifera x P. munsoniana hybrids (Marianna), P. spinosa (Sloe or blackthorn plums, 2n=32), P. insititia (Damson plums, 2n=48), and P. domestica (common plums, 2n=48).…”

The influence of rootstocks on the growth, yield and fruit quality of the plum cultivar Cacanska rana

“…U literaturi se sreću različiti podaci o uticaju podloge na krupnoću ploda sorti šljive. U nekim istraživanjima dobijene su značajne razlike između podloga (Grzyb i Sitarek, 2006;Rato et al, 2008), dok u drugim te razlike nisu bile značajne (Hrotkó et al, 2002;Sosna, 2002;Kosina, 2004;Meland, 2010;Reig et al, 2018). Naša proučavanja su pokazala da je samo podloga Fereley ispoljila statistički značajan uticaj na povećanje krupnoće ploda u odnosu na džanariku, što potvrđuje rezultate koje su dobili Grzyb i Sitarek (2006).…”

“…U našem istraživanju nisu utvrđene značajne razlike u pogledu uticaja podloga na sadržaj rastvorljive suve materije i ukupnih kiselina. To je u saglasnosti sa prethodnim istraživanjima kod šljive (Meland, 2010;Milošević i Milošević, 2012;Reig et al, 2018).…”

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

“…(Caruso et al, 1996;Bouhadida et al, 2009;Font i Forcada et al, 2012;Jimenes et al, 2018;Iglesias et al, 2019;Seker et al, 2017;Santana et al, 2020). The rootstock affects also the tree vigor, tree precocity, yield efficiency, fruit size and quality, as well (Boyhan et al, 1995;Reig et al, 2018;Reig et al, 2020;Seker et al, 2017;Shahkoomahally et al, 2020). The effects of rootstock on the grafted cultivar characteristics are mainly attributed to the change in the hormone balance induced by the rootstock, the uptake and the translocation of nutrients and water (Zarrouk et al, 2005;Mestre et al, 2015;Ben Yahmed et al, 2020;Reig et al, 2020;Shahkoomahally et al, 2020).…”
