PERFORMANCE OF ROOTSTOCKS FOR PLUMS (PRUNUS SALICINA) ON DIFFERENT SOIL TYPES

During the past decade, the plum cultivars ‘Sapphire’, ‘Pioneer’, ‘Angeleno’, ‘Laetitia’ and ‘Fortune’ were tested on a range of available potential rootstocks in five diverse and representative soil types and conditions. ‘Sapphire’ planted on high pH soils performed well in terms of yield, yield efficiency and fruit mass on the rootstocks Maridon, Marianna, SAPO778 and Viking.
GF677 showed signs of incompatibility with the scion cultivar ‘Sapphire’. Under waterlogged conditions the rootstocks Maridon, Marianna, SAPO778, Viking and Akame performed well, but both Maridon and Marianna showed signs of incompatibility with the scion ‘Pioneer’. In coarse white sandy soils free from nematodes the rootstock GF677 gave high yield efficiency as well as good fruit mass.
On sandy soils heavily infested with ring nematodes (Criconemoides xenoplax), SAPO778, GF677, Viking, Marianna and Maridon gave good yield and fruit size with the scion cultivar Laetitia, although yield in general was lower on this site.
On high potential shale soil both ‘Sapphire’ and ‘Fortune’ trees on Atlas and Viking outperformed trees on Marianna.
